This document summarizes a security analysis of a single sign-on mechanism for distributed computer networks. It identifies two impersonation attacks against an existing single sign-on scheme proposed by Chang and Lee. The first attack allows a malicious service provider to recover a user's credential after communicating with the user twice, and then impersonate the user. The second allows an outsider without credentials to freely access network services by impersonating legal or nonexistent users. It also explains flaws in the original security arguments. An improvement is proposed using efficient verifiable encryption of RSA signatures.

Understandingphone sensor and app data for enhancing security
This document discusses a system called "Secret-QA" that uses smartphone sensor and app data to generate personalized secret questions for account authentication. It aims to improve upon traditional secret questions that can easily be guessed. The system collects data from sensors, calendars, installed apps, and call history to generate questions related to a user's short-term activities and usage. A user study evaluated the memorability and security of these questions, finding that questions based on motion sensors, calendars, installed apps, and calls were best in terms of memorability and resilience to guessing attacks with or without online tools. The system aims to enhance secret question security without violating user privacy.

This document provides an abstract for a paper that proposes a new problem called Approximate Membership Localization (AML) for dictionary-based entity recognition. AML aims to locate non-overlapping substrings in a document that approximate true matches, without generating redundant overlapped substrings like Approximate Membership Extraction (AME) does. The paper proposes an algorithm called P-Prune that prunes redundant matched substrings to perform AML more efficiently. Experimental results on real-world datasets demonstrate P-Prune's efficiency over baselines and show that AML outperforms AME, including in a proposed web-based join framework application.
Android t-drive enhancing driving directions with taxi drivers’ intelligence
This paper presents a smart driving direction system that leverages taxi drivers' intelligence and experience. GPS-equipped taxis act as mobile sensors to model the dynamic traffic patterns of a city. A time-dependent landmark graph models traffic patterns and experienced drivers' route choices to provide users with the practically fastest route to a destination at a given departure time. A clustering approach estimates travel times between landmarks in different time slots. A two-stage routing algorithm then computes a customized, practically fastest route for the user based on this graph and real-world trajectory data from over 33,000 taxis over three months. Evaluation found that 60-70% of routes suggested were faster than alternatives, with 20% sharing results, and on average routes

This document summarizes an algorithm for anonymizing centralized and distributed social networks through sequential clustering. It presents two variants of an anonymization algorithm that significantly outperform the leading SaNGreeA algorithm. The algorithms are then adapted into secure distributed versions to anonymize networks where data is split between multiple data holders, preserving privacy without revealing links between nodes controlled by other data holders. This is presented as the first study of privacy preservation in distributed social networks.
Automatic temperature based exhaust fan controller
This document describes an automatic temperature-based exhaust fan controller circuit. The circuit uses a thermistor to sense room temperature, which is converted to a digital signal by an analog-to-digital converter (ADC). The microcontroller then sets the firing angle of a TRIAC, which controls the average power and therefore speed of the exhaust fan motor, based on the temperature reading. The fan speed will increase as the temperature rises to effectively regulate the room temperature.

Survey on cloud computing security techniques
This document summarizes techniques for ensuring security in cloud computing. It discusses different cloud deployment models and types of threats to cloud security. It then analyzes several intrusion detection and prevention system techniques for providing data security in cloud computing, including proof of retrievability models and cryptographic storage services. It compares the advantages and disadvantages of techniques proposed by Juels, Shacham, Bowers, and Kamara regarding their ability to verify data integrity and availability while tolerating security breaches.
AN EFFICIENT IDENTITY BASED AUTHENTICATION PROTOCOL BY USING PASSWORD
In a distributed system, authentication protocols are the basis of security to ensure that these protocols function properly. Passwords are one of the most common authentication protocol used nowadays. Because of low entropy of passwords makes the systems vulnerable to password guessing attacks. This paper presents a simple scheme that strengthens password-based authentication protocols and helps prevent dictionary attacks, replay attacks and man in the middle attacks etc., The proposed scheme presents a new password authentication protocol by using the user and server system identification/serial number. Here there is no possibility to store the user passwords so an attacker who gets the password cannot use it directly to gain immediate access and compromise security.
Efficient and Secure Single Sign on Mechanism for Distributed Network
Distributed network act as core part to access the various services which are available in the network. But the security related to distributed network is main concern. In this paper single sign-on SSO mechanism is introduced which gives access to all services by allowing to sign on only once by users. In this mechanism once user logs in to the Trusted Authority Center TAC then application or services which are register to trusted center will automatically verifies the user’s credentials details and these credentials like password or digital signature will be only one for all applications or services. Unlike all other previous mechanisms where in, if user wants to have access multiple services then for every service distinct user credentials (username, password) must be required. SSO act as single authentication window to user for admittance multiple service providers in networks. Previously introduced technique based SSO technology proved to be secure over well-designed SSO system, but fails to provide security during communication. So here emphasis is given on authentication as open problem and on to refining the already proposed SSO process. And to do this along with RSA algorithm which was used in previous SSO process, we will be using MAC algorithm, which is intended to provide secured pathway for communication over distributed network.TAC i.e. Trusted Authority Center is used for sending token integrated with private and shared public key to user.

This document proposes a scheme called AnonyControl to address privacy concerns with cloud data access. It aims to control access privileges while preserving user identity privacy. AnonyControl decentralizes the central authority across multiple attribute authorities to limit identity leakage and achieve semi-anonymity. It also generalizes file access control to privilege control to manage cloud data operations in a fine-grained way. The document describes existing access control schemes, disadvantages related to identity privacy, and how AnonyControl improves on previous work by protecting user identities through attribute distribution across authorities.Physical Layer Essay
This document discusses security issues with the Dynamic Host Configuration Protocol (DHCP) and proposes four approaches to address them. DHCP is vulnerable to spoofing and denial of service attacks because it lacks authentication. Attackers can send fake DHCP packets that cause clients to obtain incorrect IP addresses or default gateways. The four approaches proposed are: 1) DHCP snooping to filter unauthorized DHCP packets, 2) DHCP authentication using cryptographic keys, 3) Secure DHCP (S-DHCP) which adds digital signatures to packets, and 4) DHCP authentication via RADIUS. Each approach aims to authenticate DHCP messages to prevent spoofing and denial of service attacks. However, they differ in implementation complexity and adoption challenges.
APPLICATION OF MOBILE AGENTS FOR SECURITY USING MULTILEVEL ACCESS CONTROL
APPLICATION OF MOBILE AGENTS FOR SECURITY USING MULTILEVEL ACCESS CONTROLInternational Journal of Technical Research & Application
— in distributed computing environment, Mobile agents
are mobile autonomous processes which operate on behalf of
users (e.g., the Internet). These applications include a specialized
search of a middleware services such as an active mail system,
large free-text database, electronic malls for shopping, and
updated networking devices. Mobile agent systems use less
network bandwidth, increase asynchrony among clients and
servers, dynamically update server interfaces and introduce
concurrency. Due to software components, security of mobile
agent is essential in any mobile agent based application. Security
services such as Confidentiality, Integrity, Authentication,
Authorization and Non-Repudiation are discussed and combat
with by the researchers. This work is proposing a new technique
for access control area of security for the mobile agents and it
will be implemented using an example of shopping cart data
sharing for multiple levels. J0704055058
This document proposes an image-based authentication system for email to increase security. It aims to prevent shoulder surfing, TEMPEST, and brute force attacks. The system uses a three-level security approach involving a text password, image-based authentication where the user selects an image, and a one-time numeric password sent to the user's mobile phone. Communication between the client and server uses AJAX for increased interaction and speed. The system is analyzed against existing password and authentication methods and is concluded to be highly secure and user-friendly while preventing certain attacks. Future work plans to implement more secure encryption algorithms like MD5.

Survey on cloud computing security techniques
This document summarizes techniques for ensuring security in cloud computing. It discusses different cloud deployment models and types of threats to cloud security. It then analyzes several intrusion detection and prevention system techniques for providing data security in cloud computing, including proof of retrievability models and cryptographic storage services. It compares the advantages and disadvantages of techniques proposed by Juels, Shacham, Bowers, and Kamara regarding their ability to verify data integrity and availability while tolerating security breaches.
AN EFFICIENT IDENTITY BASED AUTHENTICATION PROTOCOL BY USING PASSWORD
In a distributed system, authentication protocols are the basis of security to ensure that these protocols function properly. Passwords are one of the most common authentication protocol used nowadays. Because of low entropy of passwords makes the systems vulnerable to password guessing attacks. This paper presents a simple scheme that strengthens password-based authentication protocols and helps prevent dictionary attacks, replay attacks and man in the middle attacks etc., The proposed scheme presents a new password authentication protocol by using the user and server system identification/serial number. Here there is no possibility to store the user passwords so an attacker who gets the password cannot use it directly to gain immediate access and compromise security.
Efficient and Secure Single Sign on Mechanism for Distributed Network
Distributed network act as core part to access the various services which are available in the network. But the security related to distributed network is main concern. In this paper single sign-on SSO mechanism is introduced which gives access to all services by allowing to sign on only once by users. In this mechanism once user logs in to the Trusted Authority Center TAC then application or services which are register to trusted center will automatically verifies the user’s credentials details and these credentials like password or digital signature will be only one for all applications or services. Unlike all other previous mechanisms where in, if user wants to have access multiple services then for every service distinct user credentials (username, password) must be required. SSO act as single authentication window to user for admittance multiple service providers in networks. Previously introduced technique based SSO technology proved to be secure over well-designed SSO system, but fails to provide security during communication. So here emphasis is given on authentication as open problem and on to refining the already proposed SSO process. And to do this along with RSA algorithm which was used in previous SSO process, we will be using MAC algorithm, which is intended to provide secured pathway for communication over distributed network.TAC i.e. Trusted Authority Center is used for sending token integrated with private and shared public key to user.

This document proposes a scheme called AnonyControl to address privacy concerns with cloud data access. It aims to control access privileges while preserving user identity privacy. AnonyControl decentralizes the central authority across multiple attribute authorities to limit identity leakage and achieve semi-anonymity. It also generalizes file access control to privilege control to manage cloud data operations in a fine-grained way. The document describes existing access control schemes, disadvantages related to identity privacy, and how AnonyControl improves on previous work by protecting user identities through attribute distribution across authorities.Physical Layer Essay
This document discusses security issues with the Dynamic Host Configuration Protocol (DHCP) and proposes four approaches to address them. DHCP is vulnerable to spoofing and denial of service attacks because it lacks authentication. Attackers can send fake DHCP packets that cause clients to obtain incorrect IP addresses or default gateways. The four approaches proposed are: 1) DHCP snooping to filter unauthorized DHCP packets, 2) DHCP authentication using cryptographic keys, 3) Secure DHCP (S-DHCP) which adds digital signatures to packets, and 4) DHCP authentication via RADIUS. Each approach aims to authenticate DHCP messages to prevent spoofing and denial of service attacks. However, they differ in implementation complexity and adoption challenges.

APPLICATION OF MOBILE AGENTS FOR SECURITY USING MULTILEVEL ACCESS CONTROLInternational Journal of Technical Research & Application
— in distributed computing environment, Mobile agents
are mobile autonomous processes which operate on behalf of
users (e.g., the Internet). These applications include a specialized
search of a middleware services such as an active mail system,
large free-text database, electronic malls for shopping, and
updated networking devices. Mobile agent systems use less
network bandwidth, increase asynchrony among clients and
servers, dynamically update server interfaces and introduce
concurrency. Due to software components, security of mobile
agent is essential in any mobile agent based application. Security
services such as Confidentiality, Integrity, Authentication,
Authorization and Non-Repudiation are discussed and combat
with by the researchers. This work is proposing a new technique
for access control area of security for the mobile agents and it
will be implemented using an example of shopping cart data

This document proposes an image-based authentication system for email to increase security. It aims to prevent shoulder surfing, TEMPEST, and brute force attacks. The system uses a three-level security approach involving a text password, image-based authentication where the user selects an image, and a one-time numeric password sent to the user's mobile phone. Communication between the client and server uses AJAX for increased interaction and speed. The system is analyzed against existing password and authentication methods and is concluded to be highly secure and user-friendly while preventing certain attacks. Future work plans to implement more secure encryption algorithms like MD5.

Cloudsim t-drive enhancing driving directions with taxi drivers’ intelligence
This paper presents a smart driving direction system that leverages taxi drivers' intelligence and experience. GPS-equipped taxis act as mobile sensors to model the dynamic traffic patterns of a city. A time-dependent landmark graph models traffic patterns and experienced drivers' route choices to provide users with the practically fastest route to a destination at a given departure time. A clustering approach estimates travel times between landmarks in different time slots. A two-stage routing algorithm then computes a customized, practically fastest route for the user based on this graph and real-world trajectory data from over 33,000 taxis over three months. Evaluation found that 60-70% of routes suggested were faster than alternatives, with 20% sharing results, and on average routes
Cloudsim ranking on data manifold with sink points
ECWAY Technologies provides IEEE projects and software development services from its offices in multiple cities across India. The document discusses a novel ranking approach called Manifold Ranking with Sink Points (MRSP) that addresses diversity, relevance, and importance in ranking. MRSP uses manifold ranking over a data manifold to find the most relevant objects while turning already ranked objects into "sink points" to prevent redundant objects from receiving a high rank. Experimental results on update summarization and query recommendation tasks show MRSP performs strongly compared to existing ranking approaches by better addressing the importance of diversity in ranking.
Cloudsim quality-differentiated video multicast in multirate wireless networks
This document describes a quality-differentiated video multicast scheme for multirate wireless networks called QDM. QDM aims to provide heterogeneous clients with differentiated video qualities matching their channel conditions. It first proposes a rate scheduling model to select the optimal transmission bitrate for each video frame to maximize total visual quality subject to minimum quality guarantees. It then presents QDM, a practical protocol that constructs a cluster-based structure to characterize heterogeneity and adapts transmission rates based on video quality perceived by representative cluster heads. Simulation results show QDM can efficiently adapt to network dynamics and variable video bitrates, producing a 2-5 dB gain in average video quality over leader-based approaches.

The document proposes a power allocation scheme for statistical quality-of-service provisioning in multi-relay cognitive networks. The scheme first chooses between direct transmission or relay transmission based on channel state information. It then performs efficient power allocation according to the transmission mode under average transmit power constraints, interference power constraints, and a peak interference constraint to meet quality-of-service requirements. Simulations show the proposed scheme outperforms max-min criterion and equal power allocation policies by achieving higher throughput while involving at most two relays for transmission.

Chopper based dc motor speed control
This document discusses using a chopper circuit to control the speed of a DC motor. A chopper circuit uses MOSFETs to vary the voltage applied to the motor, allowing for remote speed control. This method is more efficient and compact than previous variable resistor and transformer-based controls. Pressing buttons on the chopper circuit varies the MOSFET firing angle, decreasing motor speed as the firing angle increases. The chopper control reduces motor current, losses, temperature, noise, and increases lifetime compared to DC operation.

It formulates the joint problem of random network coding, channel assignment, and broadcast link scheduling while taking into account opportunistic overhearing, interference constraints, coding constraints, number of channels, radios per node, and fairness between unicast connections. An auction-based suboptimal solution is developed for overall network throughput optimization. Evaluation shows the algorithm can effectively use multiple radios and channels and handle fairness issues from auctions, with promising gains over traditional routing solutions

The document discusses channel allocation and routing in hybrid multichannel multiradio wireless mesh networks. It proposes an Adaptive Dynamic Channel Allocation (ADCA) protocol that considers both throughput and delay optimization in channel assignment. It also proposes an Interference and Congestion Aware Routing (ICAR) protocol for hybrid networks with static and dynamic links that balances channel usage. Simulation results show that ADCA reduces packet delay significantly without degrading throughput, and the hybrid architecture adapts better to changing traffic than static-only architectures with lower overhead and delay than existing hybrid network approaches.

Capacity of hybrid wireless mesh networks with random a ps
This paper proposes a hybrid wireless mesh network (WMN) architecture that allows the backbone to utilize random connections to access points (APs) in a wireless local area network (WLAN). Theoretical analysis shows that the capacity of a three-tier hybrid WMN is affected by the number of mesh router cells connected to APs, the ratio of access link bandwidth to backbone link bandwidth, and traffic balance among routers with AP access. Simulation results demonstrate that configuring APs and balancing traffic can significantly improve network capacity in the proposed hybrid architecture by taking advantage of wired connections through APs.

Specifically, we present two impersonation attacks. The first attack allows a malicious service provider, who has successfully communicated with a legal user twice, to recover the user’s credential and then to impersonate the user to access resources and services offered by other service providers. In another attack, an outsider without any credential may be able to enjoy network services freely by impersonating any legal user or a nonexistent user. We identify the flaws in their security arguments to explain why attacks are possible against their SSO scheme. Our attacks also apply to another SSO scheme proposed by Hsu and Chuang, which inspired the design of the Chang–Lee scheme. Moreover, by employing an efficient verifiable encryption of RSA signatures proposed by Ateniese, we propose an improvement for repairing the Chang–Lee scheme.
