Due to vast development of information technology the need of the protection of data also increases for that purpose encryption is done. The security requirements include four major aspect data confidentiality, data integrity, data authentication and data freshness. WSNs have produced enormous enthusiasm among analysts these years in view of their potential utilization in a wide assortment of uses. Sensor hubs are cheap compact gadgets with restricted handling force and vitality assets. Sensor hubs can be utilized to gather data from the earth, locally process this information and transmit the detected information back to the client. For securing that data from attack many algorithms came in existence for cryptography purpose. Be that as it may, the outstanding amongst other existing symmetric security calculation to give information security utilized these days is Advanced encryption standard (AES).

REAL-TIME INTRUSION DETECTION SYSTEM FOR BIG DATAijp2p
The objective of the proposed system is to integrate the high volume of data along with the important
considerations like monitoring a wide array of heterogeneous security. When a real time cyber attack
occurred, the Intrusion Detection System automatically store the log in distributed environment and
monitor the log with existing intrusion dictionary. At the same time the system will check and categorize the
severity of the log to high, medium, and low respectively. After the categorization, the system will
automatically take necessary action against the user-unit with respect to the severity of the log. The
advantage of the system is that it utilize anomaly detection, evaluates data and issue alert message or
reports based on abnormal behaviour.

HIERARCHICAL DESIGN BASED INTRUSION DETECTION SYSTEM FOR WIRELESS AD HOC SENS...IJNSA Journal
In recent years, wireless ad hoc sensor network becomes popular both in civil and military jobs. However, security is one of the significant challenges for sensor network because of their deployment in open and unprotected environment. As cryptographic mechanism is not enough to protect sensor network from external attacks, intrusion detection system needs to be introduced. Though intrusion prevention mechanism is one of the major and efficient methods against attacks, but there might be some attacks for which prevention method is not known. Besides preventing the system from some known attacks, intrusion detection system gather necessary information related to attack technique and help in the development of intrusion prevention system. In addition to reviewing the present attacks available in wireless sensor network this paper examines the current efforts to intrusion detection
system against wireless sensor network. In this paper we propose a hierarchical architectural design based intrusion detection system that fits the current demands and restrictions of wireless ad hoc sensor network. In this proposed intrusion detection system architecture we followed clustering mechanism to build a four level hierarchical network which enhances network scalability to large geographical area and use both anomaly and misuse detection techniques for intrusion detection. We introduce policy based detection mechanism as well as intrusion response together with GSM cell concept for intrusion detection architecture.

CERTIFICATELESS SCHEME BASED NTRU CRYPTOSYSTEM FOR AD-HOC UWB-IR NETWORKijwmn
From the radar and military research world’s, the Ultra-WideBand Impulse Radio (UWB-IR) was
adopted in the telecommunications world in the 1990’. Currently, the UWB-IR technology is an
interesting candidate for close range Wireless Sensors Networks (WSNs). It is particularly attractive
for industrial sensor networks due to its resilience to multipath interference, simple transceiver
circuitry, accurate ranging ability, and low transmission power. In order to secure data and communications
in the Ad-Hoc UWB-IR networks, UWB-IR requires suitable encryption protocols. In
this paper, we review and summarize the IEEE 802.15.4 security sub-layer protocol of UWB-IR
based Symmetric Key Cryptography scheme. Then, we highlight the different vulnerabilities and
weaknesses present in this type of scheme. Finally, we prove, after a deep examination of multiple
Public Key Cryptography (PKC) schemes, that the certificateless one is the most suitable for Ad-Hoc
UWB-IR networks characterized by nodes mobility. Indeed, we have also evaluated and analyzed the
different public key cryptosystems (PKCS) and concluded that NTRU is the most optimum public
key cryptosystem to be used with the certificateless scheme in order to secure data and communications
in Ad-Hoc UWB-IR Networks. This is due to the fact that it is the fastest PKCS to provide
different security levels at a high speed with very constrained resources.
Secure and privacy preserving data centric sensor networks with multi query o...eSAT Journals
Abstract
In large-scale Wireless Sensor Networks the effective use of the vast amounts of data gathered will require scalable, self-organizing, and energy-efficient data dissemination and data retrieval techniques. Data Centric Sensor (DCS) networks is a better approach in which the sensor nodes send the sensed data to a designated sensor node whose name is associated with sensed data. However, due to unattended nature of Wireless Sensor Networks, these sensor nodes are susceptible to different types of attacks. The attacker may compromise these storage nodes and get data of his interest. In this paper we propose a Secure and Privacy Preserving Data Centric Sensor Networks that includes security and privacy support to DCS networks. We use multi level key structure and cryptographic algorithms to provide security. In addition, we propose a multi-query optimization technique that aggregates similar queries for a small periodic time and construct a query message. This reduces the number of messages required to serve multiple similar queries. Simulation and experimental results show that our work provides a secure privacy preserving data centric sensor network based on cryptographic keys and reduces the message overhead and incurs a minimum communication cost compared to previous works

he Wireless Sensor Networks (WSNs) have spread its roots in almost every application. Owing to their scattered nature of sensor nodes, they are more prone to attacks. There are certain applications e.g. military, where sensor data‟s confidentiality requirement during transmission is essential. Cryptography has a vital role for achieving security in WSNs.WSN has resource constraints like memory size, processing speed and energy consumption which bounds the applicability of existing cryptographic algorithms for WSN. Any good security algorithms has higher energy consumption by the nodes, so it‟s a need to choose most energy-efficient cryptographic encryption algorithms for WSNs. This paper surveys different asymmetric algorithms such as RSA, Diffie-Hellman, DSA, ECC, hybrid and DNA cryptography. These algorithms are compared based on their key size, strength, weakness, attacks and possible countermeasures in the form of table.

As sensor networks edge closer towards wide-spread placement, security issues become a central concern. So far, much research has concentrated on making sensor networks feasible and useful, and has not focused on security.
We present a set of security building blocks optimized for resource constrained environments and wireless communication. SPINS has two secure building blocks: SNEP and TESLA. SNEP provides the following important baseline security primitives: Data confidentiality, two-party data authentication, and data freshness. A particularly hard problem is to provide effective broadcast authentication, which is an important mechanism for sensor networks. TESLA is a new protocol which provides authenticated broadcast for severely resource-constrained surroundings. We realized the above protocols, and show that they are practical straighly on minimal hardware: the performance of the protocol suite easily matches the data rate of our network. Additionally, we prove that the suite can be used for building higher level protocols

Transferring the secure data becomes vital for the important data of every days life. The system is a secure data transferring, combining the two techniques, Advance Encryption Standard AES and RSA. The data file is encrypted by using AES with the randomly generated key. This key is also encrypted by RSA using the receivers public key. The encrypted data file and encrypted key file are combined to form an output file to send to the receiver. The file at the receivers side is separated into two files, the encrypted data file and encrypted key file. The encrypted key file is decrypted by RSA method using the receivers private key. The AES key is acquired, the encrypted data file is then decrypted by AES method using the acquired AES key. The system includes file transferring process based on the Java socket technology.

A dynamic data encryption method based on addressing the data importance on ...IJECEIAES
The rapid growth of internet of things (IoT) in multiple areas brings research challenges closely linked to the nature of IoT technology. Therefore, there has been a need to secure the collected data from IoT sensors in an efficient and dynamic way taking into consideration the nature of collected data due to its importance. So, in this paper, a dynamic algorithm has been developed to distinguish the importance of data collected and apply the suitable security approach for each type of data collected. This was done by using hybrid system that combines block cipher and stream cipher systems. After data classification using machine learning classifiers the less important data are encrypted using stream cipher (SC) that use rivest cipher 4 algorithm, and more important data encrypted using block cipher (BC) that use advanced encryption standard algorithm. By applying a performance evaluation using simulation, the proposed method guarantees that it encrypts the data with less central processing unit (CPU) time with improvement in the security over the data by using the proposed hybrid system.

Certain Investigations on Security Issues in Smart Grid over Wireless Communi...IJTET Journal
Smart Grid (SG) communication has recently received significant attentions to facilitate intelligent and distributed electric power transmission systems. The advent of the smart grid promises to user in an era that will bring intelligence, efficiency, and optimality to the power grid. Most of these challenges will occur as an Internet-like communications network is super imposed on top of the current power grid using wireless mesh network technologies with the 802.15.4, 802.11 and WiMAX Standards. Each of these will expose the power grid to security threats. Wireless communication offers the benefits of low cost, rapid deployment, shared communication medium, and mobility. It causes many security and privacy challenges. The concept of dynamic secret is applied to design an encryption scheme for smart grid in wireless communication. Between two parties of communication, the previous packets are coded as retransmission sequence, where retransmitted packet is marked as ―1‖ and the other is marked as ―0‖.During the communication, the retransmission sequence is generated at both sides to update the dynamic encryption key. Any missing or misjudging sequence would prevent the adversary from achieving key. A Smart Grid platform is built, employing the ZigBee protocol for wireless communication. The Simulation results show that the retransmission and packet loss in ZigBee communication are inevitable and unpredictable and it is impossible of the adversary to track the updating of dynamic encryption key. Even though the DES scheme can protect the encryption key from attackers, the hackers can obtain the keys some time, due to the block size 64 bits used by DES that makes the adversary (hacker) to hack the data. It introduces vulnerabilities and liner crypt analysis; this can be achieved by using AES scheme. The AES uses 128 bits block size for a single encryption key a data of 256 billion gigabytes can be transmitted thus its provide much more safety to user from hacker and it reduces the end to end delay and increases packet transmission rate.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

Abstract— Due to vast development of information
technology the need of the protection of data also increases
for that purpose encryption is done. The security
requirements include four major aspect data confidentiality,
data integrity, data authentication and data freshness.
WSNs have produced enormous enthusiasm among analysts
these years in view of their potential utilization in a wide
assortment of uses. Sensor hubs are cheap compact gadgets
with restricted handling force and vitality assets. Sensor
hubs can be utilized to gather data from the earth, locally
process this information and transmit the detected
information back to the client. For securing that data from
attack many algorithms came in existence for cryptography
purpose. Be that as it may, the outstanding amongst other
existing symmetric security calculation to give information
security utilized these days is Advanced encryption standard
(AES).

I. INTRODUCTION:
Wireless sensor networks (WSN) consists of autonomous
sensor nodes attached to one or base stations. One of the
main goals of wireless sensor networks is to carry reliable
information from one node to another node in a network. As
Wireless sensor systems keeps on developing, they wind up
powerless against attacks and thus the requirement for
effective security components. ID of reasonable
cryptography for remote sensor systems is an imperative
test because of limitation of energy, computation capability
and storage resources of the sensor nodes. In this paper we
have implemented Encryption algorithm AES (Advanced
Encryption Standard) to provide sufficient levels of security
for WSN. Advanced encryption standard has favorable
position of being actualized on both hardware and software.
Advanced encryption standard depends on "substitution-
permutation network". It uses 10, 12, or 14 rounds in
algorithm and the key size, can be 128, 192, or 256 bits
depending on the number of rounds. The AES is widely
used to encrypt the confidential data for security purposes.
1.1 AUTHENTICATION: The process of proving one's
identity. It is another part of data security that we encounter
with everyday computer usage. Just think when you log into
your email, or blog account. The simple sign-in process is a
form of authentication that allows you to log into
applications, files, folders and even an entire computer
system. Once signed in, you have different given benefits
until the point when logging out. Some system will cancel a
session if your machine has been idle for a certain amount
of time, requiring that you prove authentication once again
to re-enter. The straightforward sign-on plot is likewise
executed into solid client authentication systems. Be that as
it may, it expects people to login utilizing various
components of authentication. Non-repudiation: In this, the
recipient should know whether the sender isn't faking.For
example, if suppose when one purchases something online,
one should be sure that the person whom one pays is not
faking.
1.2 INTEGRITY: Many a times information should be
refreshed yet this must be finished by authenticated people.
1.3 Privacy/confidentiality: Ensuring that nobody can read
the message aside from the expected receiver. Encryption is
the way toward clouding data to make it mixed up without
extraordinary learning. Encryption has been utilized to
ensure correspondences for a considerable length of time,
however just associations and people with an uncommon
requirement for mystery had made utilization of it. In the
mid-1970s, in number encryption rose up out of the sole
safeguard of cryptic government organizations into people
in general space, and is presently utilized as a part of
securing broadly utilized frameworks, for example, Internet

online business, cell phone systems and bank programmed
teller machines.
II. AES ALGORITHM
NIST started its push to build up the AES, a symmetric key
encryption algorithm, and made an overall open require the
calculation to succeed DES. At first 15 algorithms were
chosen, which was then decreased down to 4 algorithms,
RC6, Rijndael, Serpent and Two-angle, which were all
iterated square figures. The four finalists were altogether
resolved to be qualified as the AES. The calculation must be
reasonable over an extensive variety of hardware and
software systems. The calculation must be moderately basic
also. After broad audit the Rijndael calculation was been the
AES calculation.

2.1 THE RIJNDAEL ALGORITHM:
For Rijndael, the length of both the square to be encoded
and the encryption key are not settled. They can be
autonomously indicated to 128, 192 or 256 bits. The
quantity of rounds, nonetheless, differs as indicated by the
key length. It can be equivalent to 10, 12 and 14 when the
key length is 128bits, 192 bits and 256 bits, individually.
The fundamental parts of Rijndael are basic scientific,
legitimate, and table query tasks. The last is really a
composite capacity of a reversal over Galois Field (GF)
with a relative mapping. Such structure makes Rijndael
appropriate for equipment execution.
III. WIRELESS SENSOR NETWORK:
In a typical WSN we see following network components –
Sensor motes (Field devices) – Field devices are mounted in
the process and must be capable of routing packets on
behalf of other devices. In most cases they characterize or
control the process or process equipment. A router is a
special type of field device that does not have process
sensor or control equipment and as such does not interface
with the process itself.
Gateway or Access points – A Gateway enables
communication between Host application and field devices.
Network manager – A Network Manager is responsible for
configuration of the network, scheduling communication
between devices (i.e., configuring super frames),
management of the routing tables and monitoring and
reporting the health of the network.
Security manager – The Security Manager is responsible for
the generation, storage, and management of keys[5,18,19].
IV. WSN SECURITY ANALYSIS
Effortlessness in Wireless Sensor Network with asset
obliged hubs makes them greatly defenseless against
assortment of assaults. Aggressors can listen in on our radio
transmissions, infuse bits in the channel, replay already
heard bundles and some more. Securing the Remote Sensor
Network needs to make the system bolster all security
properties: privacy, uprightness, credibility and
accessibility. Aggressors may send a scarcely any
malevolent hubs with comparable equipment abilities as the
honest to goodness hubs that may conspire to assault the
framework helpfully. The aggressor may happen upon these
malevolent hubs by buying them independently, or by
"turning" a couple of honest to goodness hubs by catching
them furthermore, physically overwriting their memory.
Likewise, in a few cases plotting hubs may have high
caliber
interchanges joins accessible for planning their assault.
Sensor center points may not be change safe and if a foe
deals a center point, she can remove all key material, data,
and code set away on that center point. While change
security might be a viable obstruction for physical node
bargain for a few systems, we don't see it as a broadly

useful arrangement. To a great degree compelling alter
protection tends to include critical per-unit cost, also, sensor
hubs are proposed to be exceptionally economical.
4.1 AES (RIJNDAEL) OVERVIEW
Rijndael (articulated as in "rain doll" or "rhine dahl") is a
piece figure outlined by Joan Daemen and Vincent Rijmen,
the two cryptographers in Belgium. Rijndael can work over
a variable-length piece utilizing variablelength keys; the
adaptation 2 particular submitted to NIST portrays
utilization of a 128-, 192-, or 256-piece key to scramble
information obstructs that are 128, 192, or 256 bits in
length; take note of that each of the nine mixes of key
length and square length are conceivable. The calculation is
composed in such a way that piece length or potentially key
length can without much of a stretch be reached out in
products of 32 bits and it is particularlyintended for
proficient execution in equipment or programming on a
scope of processors. The outline of Rijndael was
unequivocally impacted by the piece figure.
V. METHODOLOGY
Data encryption is an imperative part of applying security to
a wireless sensor systems. Despite the fact that transmission
of information is the most energy consuming action in a
remote sensor hub, it is likewise essential to choose a
energy effective figure to limit energy utilization of the
sensor hub. Subsequently symmetric key figure is
commonly used to scramble information for transmission.
Numerous block ciphers, for example, Advanced
Encryption Standard (AES) utilizes various rounds of
activities, for example, substitutions and linear
transformations.
Secured Power Aware Routing For Wireless Sensor
Security is an important factor for performance and energy
efficiency in many applications. Security serves as an
important role in war zone, premise protection surveillance,
airports, hospitals etc. Because of the property of sensor
devices, the sensor systems may effortlessly be
compromised by attackers who send manufactured or
altered messages. To keep data and communication systems
from unlawful delivery and modification, message
verification and distinguishing proof should be analyzed
through certificated mechanisms. The messages transmitted
from the sensor hubs over a remote sensor systems ought to
be verified by the collector. The strategy of cryptography is
used for this part. It is a test for the researchers to find
proper cryptography for remote sensor orchestrates on
account of the limitations in control efficiency, computation
capability and awesome stockpiling capacities.
VI. CONCLUSION
The proposed convention has been actualized utilizing
Network Simulator (NS2). The execution measurements
depends on control utilization, bundle conveyance
proportion. The AES Based Secure Transmission in
Wireless Sensor Networks accomplishes the application
determined correspondence delays at low vitality cost by
powerfully adjusting transmission control and directing
choices alongside consolidating a novel cryptosystem for
security. To keep data and correspondence frameworks
from unlawful conveyance and alteration, message
confirmation and ID is inspected through guaranteed
instruments. The messages transmitted from the sensor hubs
over a remote sensor systems is validated by the
beneficiary. The method of cryptography is utilized for this
system. The sender utilizes the proposed encryption
calculation to make an impression on the beneficiary,
through unsecured channel, and the collector utilizes the
proposed unscrambling calculation to peruse the got
message. The novel cryptosystem based Secured Power
Aware Routing Protocol (SPARP) upgrades Quality of
Service (QoS, for example, parcel conveyance proportion,
delay and diminishes the power utilization between the hubs
when bundles are transmitted.
