A fast static analysis approach to detect exploit code inside network flowsUltraUploader
This document proposes a static analysis approach to detect exploit code within network flows. It aims to distinguish between data and executable code by looking for evidence of meaningful data and control flow patterns within binary code fragments recovered through disassembly, without knowing the exact location of the code. The approach is evaluated on real network trace data and is shown to detect a variety of exploit code, including polymorphic and metamorphic variants. It also automatically generates precise signatures to complement signature-based detection systems.

A Survey on Cloud-Based IP Trace Back FrameworkIRJET Journal
This document summarizes a survey of cloud-based IP traceback frameworks. It proposes a cloud-based traceback architecture with three layers: an intra-AS layer where traceback servers in each Autonomous System (AS) collect and store traffic flow data; a traceback as a service layer where ASes expose their traceback capabilities; and an inter-AS logical links layer to facilitate efficient traceback across ASes. It then focuses on access control to prevent unauthorized users from requesting traceback information. To address this, it proposes a temporal token-based authentication framework called FACT that embeds tokens in traffic flows and delivers them to end hosts to authenticate traceback queries. The framework aims to ensure only actual recipients of packets can initiate traceback for those packets.
ANALYSIS OF THE SECURITY OF BB84 BY MODEL CHECKINGIJNSA Journal
Quantum Cryptography or Quantum key distribution (QKD) is a technique that allows the secure distribution of a bit string, used as key in cryptographic protocols. When it was noted that quantum computers could break public key cryptosystems based on number theory extensive studies have been undertaken on QKD. Based on quantum mechanics, QKD offers unconditionally secure communication. Now, the progress of research in this field allows the anticipation of QKD to be available outside of laboratories within the next few years. Efforts are made to improve the performance and reliability of the implemented technologies. But several challenges remain despite this big progress. The task of how to test the apparatuses of QKD For example did not yet receive enough attention. These devises become complex and demand a big verification effort. In this paper we are interested in an approach based on the technique of probabilistic model checking for studying quantum information. Precisely, we use the PRISM tool to analyze the security of BB84 protocol and we are focused on the specific security property
of eavesdropping detection. We show that this property is affected by the parameters of quantum channel and the power of eavesdropper.

The presented thesis in this paper is another discussion on the problem or problem-
complex: What is Web 2.0? How it works? Is it vulnerable to its security scope? How can
one utilize and share Web 2.0, knowing in this interactive collaboration, how to protect
himself?
In this bachelor work the reader will find history information, discussion on the evolu-
tion of the Web standards and most common Web 2.0 attacking classes. Two examples of
important Web 2.0 attacking vectors shall be discussed in depth, in such manner as an ana-
lysis and examples on the attacking techniques, deliberation on the trends in attack preven-
tion methods, discussion on the tools according to these.
This paper should give a good classification on the proposed examples of Web 2.0 at-
tacks, make a conclusion on behalf of the Life Cycle and security standards for the modern
Web 2.0 implementations, and perhaps offer some interesting proposals.
This document is the final honors project report submitted by Antony Law comparing the security of simple versus complex passwords when implemented in WLAN security frameworks WPA and WPA2. The project aims to evaluate the impact of password complexity on resistance to password cracking attacks. An experiment will be conducted using the aircrack-ng and oclHashcat password cracking tools against various simple and complex password scenarios to determine differences in success rates and cracking times. The results will help understand how password complexity affects security and provide guidance to users on creating more secure passwords.

This project aims to analyze and emulate anomaly detection techniques for low-rate TCP denial of service attacks using the DETERLab testbed. The researchers plan to design an extensive anomaly checkpoint detection methodology. They propose a modified likelihood ratio algorithm to detect changes in network traffic statistics. The algorithm will be tested on legitimate and attack traffic in DETERLab while analyzing detection statistics and congestion windows. Results will help evaluate the ability to rapidly detect attacks while limiting false alarms.
The document discusses covert channels and steganography. It defines a covert channel as a means for processes or users to exchange information in violation of security policy. It also defines the goal of steganography as hiding the very existence of secret messages, unlike encryption which hides only the content. The proposed system focuses on how two entities can securely communicate secretly over a public channel without being detected by a third party. It gives definitions for secure steganography and constructions that have optimal bandwidth and security against passive adversaries.
Automatic static unpacking of malware binariesUltraUploader
This document discusses an approach to automatically unpacking malware binaries through static analysis techniques. It begins by explaining the problem with relying solely on dynamic analysis for unpacking malware, as dynamic techniques are susceptible to anti-monitoring defenses. The document then presents its approach, which first uses program analysis to identify potential self-modifying code that could indicate unpacking. It focuses on finding "transition points" where control flow moves from unmodified to modified code. The code between these transition points represents the static unpacker that can be analyzed to perform unpacking without prior knowledge of the packing algorithm. Control and data flow analysis are then used to identify and potentially neutralize any dynamic defenses in the unpacker.

Abstract:
The AVISPA Model Checker is a tool for automated validation and verification of security
protocols. It provides a push-button web-based software- and hardware-independent interface and
installation binaries for UNIX-based Operating Systems.
It belongs to the group of the state-of-the-art Model Checkers and uses a modular and descriptive
formal language for specifying industrial-scale security protocols.
The different back-ends of the AVISPA tool implement new optimized analysing techniques for
automated protocol verification.
Therefore the researcher/scientist can prove even bigger in their specification protocols in a short
time and in a user-friendly way.
New cryptographic attacks are explored using the AVISPA tool and the Model-Checker covers
widest range of the modern authentication internet protocols, regarding their security validation.
In protocol tunnelling, one application protocol is encapsulated within another carrier protocol possibly to circumvent firewall policy. Application-layer tunnels are a significant security and resource abuse threat for networks. The existing techniques for identification of applications running across the network, for example packet data analysis techniques are not always successful, especially for applications which use encrypted tunnels. This work describes a statistical approach to detect applications which are running using application layer tunnels. A fast machine learning algorithm, k-Nearest Neighbours is demonstrated to be able to perform the detection of tunnelled applications based on statistical features obtained from the network applications running inside protocol tunnels. The scalability of the mechanism is also investigated.
This document provides an overview of network sniffing and packet analysis using Wireshark. It discusses why sniffing is useful for understanding network activity, troubleshooting issues, and performing computer forensics. The document outlines topics like the basic techniques of sniffing, an introduction to Wireshark and its features, analyzing common network protocols, and examples of case studies sniffing could be used for. It emphasizes that patience is a prerequisite and encourages interactive discussion.
Formal Modeling and Verification of Trusted OLSR Protocol Using I-SPIN Model...IOSR Journals
The document describes formal modeling and verification of the Trusted Optimized Link State Routing Protocol (TOLSR) using the I-SPIN model checker and PROMELA language. It summarizes that the basic OLSR protocol has vulnerabilities to attacks from malicious nodes. To address this, a trust-based framework is proposed where trust values between nodes are incorporated into the protocol's functioning. The TOLSR protocol is formally modeled and verified in PROMELA at different levels of complexity. The model checking results show the TOLSR protocol specifications are validated and memory usage increases with complexity, demonstrating the effectiveness of formal modeling for developing secure and reliable ad hoc network routing protocols.
This document summarizes a research paper that presents a scheme called Hydan for steganographically embedding information in x86 program binaries. The scheme defines sets of functionally equivalent instructions and uses a key-derived selection process to encode bits by choosing the appropriate instructions from each set. Testing showed an encoding rate of about 1 bit for every 110 bits of program code. This capacity could be used for watermarking, fingerprinting executables, or encoding a digital signature in the program binaries. The document reviews related work in classical and code steganography and information hiding.
Survey of universal authentication protocol for mobile communicationAhmad Sharifi
This document provides a survey of universal authentication protocols. It begins with an introduction to authentication protocols and some examples of protocols that were later found to have flaws. It then discusses the cryptographic prerequisites for authentication protocols, including symmetric key cryptography, classical cryptography, and modern cryptography. The document describes several block cipher algorithms and modes of using block ciphers. The overall purpose is to provide an overview of authentication protocols and related cryptographic concepts.
A Modified Technique For Performing Data Encryption & Data DecryptionIJERA Editor
In this age of universal electronic connectivity of viruses and hackers of electronic eavesdropping and electronic fraud, there is indeed needed to store the information securely. This, in turn, led to a heightened awareness to protect data and resources from disclosure, to guarantee the authenticity of data and messages and to protect systems from network-based attacks. Information security via encryption decryption techniques is a very popular research area for many people’s over the years. This paper elaborates the basic concept of the cryptography, specially public and private cryptography. It also contains a review of some popular encryption decryption algorithms. A modified method is also proposed. This method is fast in comparison to the existing methods.
Finding Bad Code Smells with Neural Network Models IJECEIAES
Code smell refers to any symptom introduced in design or implementation phases in the source code of a program. Such a code smell can potentially cause deeper and serious problems during software maintenance. The existing approaches to detect bad smells use detection rules or standards using a combination of different object-oriented metrics. Although a variety of software detection tools have been developed, they still have limitations and constraints in their capabilities. In this paper, a code smell detection system is presented with the neural network model that delivers the relationship between bad smells and object-oriented metrics by taking a corpus of Java projects as experimental dataset. The most well-known objectoriented metrics are considered to identify the presence of bad smells. The code smell detection system uses the twenty Java projects which are shared by many users in the GitHub repositories. The dataset of these Java projects is partitioned into mutually exclusive training and test sets. The training dataset is used to learn the network model which will predict smelly classes in this study. The optimized network model will be chosen to be evaluated on the test dataset. The experimental results show when the modelis highly trained with more dataset, the prediction outcomes are improved more and more. In addition, the accuracy of the model increases when it performs with higher epochs and many hidden layers.
Quantum Cryptography Approach for Resolving Cyber Threatsijtsrd
The research work focused on the future of the internet security transaction without allowing unauthorized user from accessing the secret document. The system was implemented with python flask framework been the lightest micro framework. The quantum key distribution generator model used is the BB84. Users can create account one the sender and other receiver then peered together in single communication channel. The sender attach file and send it in an encrypted manner to be received by receiver on presenting the same quantum key used for encrypting it. Once the eavesdropper click the link of the protocol, an alarm is raised and the system quantum key is change instantly and committed into the database. The other application is the Quantum Simulator, this application is used for generating a simulation for a quantum cryptography. Madubuezi Christian Okoronkwo | Onwuzo J. C | Gregory E.

The document provides details about a project report on security extensibility in steganography. It discusses existing steganography techniques like the Least Significant Bit (LSB) algorithm and their drawbacks. It proposes developing a new Security Extensibility Algorithm (SRM algorithm) to provide better security for steganography compared to the LSB algorithm. The SRM algorithm would be used for steganography, cryptography, password authentication, and digital watermarking. The report outlines the system analysis, design, and testing of the proposed SRM algorithms to enhance security when embedding secret messages within digital files.

The Mayas lived in scattered cities across Mesoamerica and developed powerful city-states like Tikal and Calakmul through agriculture and trade. They had a complex society led by rulers and priests and built towering temples and pyramids. The Mayas developed advanced mathematics, astronomy, and a hieroglyphic writing system to record their history and culture. While the exact reasons are unknown, the Maya civilization eventually declined, though their culture and descendants still exist today.

Shane Bowers wrote a speech essay about planning a Parent's Night Out event at his church. He struggled with budgeting for the event due to issues distributing flyers on time. This led to low registration numbers initially. On the night of the event, an unregistered child with allergies arrived, which caused last minute changes. Despite challenges, the event was a success that taught Shane he is better working with a team and that event planning is not a good career fit for him. He will instead pursue becoming an ultrasound technician.
This document describes a dream had by Abraham Lincoln in which he saw a catafalque with a corpse wrapped in funeral vestments surrounded by mourning crowds and guards in the White House. When Lincoln demands who has died, a soldier answers "The President, he was killed by an assassin." The crowd then bursts into loud grief, awakening Lincoln from the dream.

Factors Contributing to the Decline of the Anchovy Fisheries in Krueng Raya B...Zulhamsyah Imran
This document summarizes a study on factors contributing to the decline of anchovy fisheries in Krueng Raya Bay, Indonesia. The study found that anchovy production peaked at 2,072 tons in 1999 but declined sharply to 171 tons after the 2004 tsunami. While production fluctuated between 126-279 tons from 2006-2012, it remained well below pre-tsunami and predicted maximum sustainable yield levels. The decline is attributed to increasing fishing effort through more lift net boats, destructive fishing gears, and degradation of coral reefs and mangroves from pollution and other human impacts. The tsunami exacerbated the decline but other anthropogenic factors likely had a greater long-term impact on depleting the anchovy stocks.

Virtual Labs SniffingConsider what you have learned so far AlleneMcclendon878
Virtual Labs: Sniffing
Consider what you have learned so far about Sniffing as you review the objectives and scenario below. Complete the lab that follows on EC-Council's website using the link below.
Objective
Sniffing is performed to collect basic information from the target and its network. It helps to find vulnerabilities and select exploits for an attack. It determines the network, system, and organizational information.
The objective of this lab is to make students learn to sniff a network and analyze packets for any attacks on the network. The primary objectives of this lab are to:
Sniff the network
Analyze incoming and outgoing packets
Troubleshoot the network for performance
Secure the network from attacks
Scenario
“Sniffing” is the process of monitoring and capturing data packets passing through a given network using software or hardware devices. There are two types of sniffing: passive and active.
Passive sniffing refers to sniffing on a hub-based network; active sniffing refers to sniffing on a switch-based network.
Although passive sniffing was predominant in earlier days, proper network-securing architecture has been implemented (switch-based network) to mitigate this kind of attack. However, it contains a few loopholes in switch-based network implementation that can open doors for an attacker to sniff network traffic.
Attackers hack the network using sniffers, where he/she mainly targets the protocols vulnerable to sniffing. Some of the protocols vulnerable to sniffing include HTTP, FTP, SMTP, POP, and so on. The sniffed traffic comprises FTP and Telnet passwords, chat sessions, email and web traffic, DNS traffic, and so on. Once attackers obtain such sensitive information, they might attempt to impersonate target user sessions.
Thus, it is essential to assess the security of the network’s infrastructure, find the loopholes in it and patch them up to ensure a secure network environment. So, as an ethical hacker/penetration tester, your duties include:
Implementing network auditing tools such as Wireshark, and Cain & Abel, etc. in an attempt to find loopholes in the network.
Using security tools such as PromqryUI to detect attacks on the network, and so on.
The lab this week will provide you with real-time experience in sniffing.

Lab Description:
Data traversing an HTTP channel is prone to MITM attacks, as it flows in plain-text format. Network administrators can use sniffers to troubleshoot network problems, examine security problems, and debug protocol implementations. However, an attacker can use tools such as Wireshark and sniffs the traffic flowing between the clien ...
THE METHOD OF DETECTING ONLINE PASSWORD ATTACKS BASED ON HIGH-LEVEL PROTOCOL ...IJCNCJournal
Although there have been many solutions applied, the safety challenges related to the password security mechanism are not reduced. The reason for this is that while the means and tools to support password attacks are becoming more and more abundant, the number of transaction systems through the Internet is increasing, and new services systems appear. For example, IoT also uses password-based authentication.
In this context, consolidating password-based authentication mechanisms is critical, but monitoring measures for timely detection of attacks also play an important role in this battle. The password attack detection solutions being used need to be supplemented and improved to meet the new situation. In this
paper we propose a solution that automatically detects online password attacks in a way that is based solely on the network, using unsupervised learning techniques and protected application orientation. Our solution therefore minimizes dependence on the factors encountered by host-based or supervised learning solutions. The certainty of the solution comes from using the results of in-depth analysis of attack
characteristics to build the detection capacity of the mechanism. The solution was implemented experimentally on the real system and gave positive results.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

Title :Robust Video Data Hiding using Forbidden Zone Data Hiding and Selective Embedding
Language : C#
Project Link :
http://kasanpro.com/p/c-sharp/robust-video-data-hiding-forbidden-zone-data-hiding-selective-embedding
Abstract : Video data hiding is still an important research topic due to the design complexities involved. We propose
a new video data hiding method that makes use of erasure correction capa- bility of repeat accumulate codes and
superiority of forbidden zone data hiding. Selective embedding is utilized in the proposed method to determine host
signal samples suitable for data hiding. This method also contains a temporal synchronization scheme in order to
withstand frame drop and insert attacks. The proposed framework is tested by typical broadcast material against
MPEG- 2, H.264 compression, frame-rate conversion attacks, as well as other well-known video data hiding methods.
The decoding error values are reported for typical system parameters. The simulation results indicate that the
framework can be successfully utilized in video data hiding applications.

Title :Safeguarding Quantum Key Distribution Through Detection Randomization
Language : Java
Project Link : http://kasanpro.com/p/java/safeguarding-quantum-key-distribution-through-detection-randomization
Abstract : We propose and experimentally demonstrate a scheme to render the detection apparatus of a quantum
key distribution system immune to the main classes of hacking attacks in which the eavesdropper explores the
back-door opened by the single-photon detectors. The countermeasure is based on the creation of modes that are not
deterministically accessible to the eavesdropper. We experimentally show that the use of beamsplitters and extra
single-photon detectors at the receiver station passively creates randomized spatial modes that erase any knowledge
the eavesdropper might have gained when using bright-light faked states. Additionally, we experimentally show a
detectorscrambling approach where the random selection of the detector used for each measurement--equivalent to
an active spatial mode randomization--hashes out the side-channel open by the detection efficiency mismatch-based
attacks. The proposed combined countermeasure represents a practical and readily implementable solution against
the main classes of quantum hacking attacks aimed on the single-photon detector so far, without intervening on the
inner working of the devices.

Title :Postprocessing of the Oblivious Key in Quantum Private Query
Language : C#
Project Link : http://kasanpro.com/p/c-sharp/postprocessing-oblivious-key-quantum-private-query
Abstract : Private query is a kind of cryptographic protocols to protect both users' privacies in their communication.
For instance, Alice wants to buy one item from Bob's database. The aim of private query is to ensure that Alice can
get only one item from Bob, and simultaneously, Bob cannot know which one was taken by Alice. In pursuing high
security and efficiency, some quantum private query protocols were proposed. As a practical model, Quantum-
Oblivious-Key-Transfer (QOKT)-based private query, which utilizes a QOKT protocol to distribute oblivious key
between Alice and Bob and then applies the key to achieve the aim of private query, has drawn much attention. Here,
we focus on postprocessing of the oblivious key, and the following two contributions are achieved. 1) We analyze
three recently proposed dilution methods and find two of them have serious security loophole. That is, Alice can
illegally obtain much additional information about Bob's database by multiple queries. For example, Alice can obtain
the whole database, which contains 104 items, by only 53.4 queries averagely. 2) We present an effective
error-correction method for the oblivious key, which can address the realistic scenario with channel noises and make
QOKT-based private query more practical.

Title :Encryption and Multiplexing of Fingerprints for Enhanced Security
Language : Matlab
Project Link : http://kasanpro.com/p/matlab/encryption-multiplexing-fingerprints-enhanced-security
Abstract : A novel cryptographic technique is proposed for enhanced security of fingerprint information. An
orthogonal coding scheme is developed to encrypt the given fingerprint image. Multiple encrypted fingerprint images
are then mixed together by using a multiplexing process. The proposed encryption and multiplexing technique not
only enhances the security of confidential fingerprint information by making the information inaccessible to any
intruder having a random code, but also improves the system resource utilization by reducing the storage and/or
transmission bandwidth requirement. The salient features of the technique is that any authorized user can retrieve the
corresponding fingerprint information from the complex encrypted and multiplexed image by a single decryption
process with the authentic key. The proposed cryptographic technique involves a simple architecture by not requiring
any mathematical transformation. Performance of the technique is investigated through computer simulation
employing real-life fingerprint images.
Title :Steganography Using the Twelve Square Substitution Cipher and an Index Variable
4. Language : Matlab
Project Link : http://kasanpro.com/p/matlab/steganography-using-twelve-square-substitution-cipher-index-variable
Abstract : In this paper we are proposing a technique for secret communication between Alice and Bob. We are
using both cryptography and steganography. Firstly, we encrypt the secret message using our new cipher algorithm
called twelve square substitution cipher algorithm, and then embed the cipher text in the carrier image in 6th and 7th
bit locations or 7th and 8th bit locations or 6th and 8th bit locations of the different pixels (bytes) of the carrier image
depending on the value of an index variable. Here the 8th bit means the least significant bit (LSB) location, the 7th bit
means the LSB minus one location and the 6th bit means the LSB minus two location. The index variable value can
be 0 or 1 or 2. The index variable value will change from 0 to 1 or 1 to 2 or 2 to 0 after each embedding. The initial
value of the index variable depends upon the length of the cipher text. After embedding the resultant image should be
sent to the receiver and receiver should retrieve the cipher text from the said locations and then decrypt by using the
twelve square cipher algorithm to get the secret message. The embedding locations are not same in all pixels, so it is
a stronger approach. The algorithm is implemented using Java programming language. The experimental results says
that the algorithm performs well.
