Design And Hardware Implementation Of A Novel Scrambling Security Algorithm For Robust Wireless Local Area Networks

The IEEE802.11 standard for wireless networks includes a Wired Equivalent Privacy (WEP) protocol, which is a popular wireless secure communication stream cipher protocol approach to network security used to protect link-layer communications from eavesdropping and other attacks. It allows user to communicate with the user; sharing the public key over a network. It provides authentication and encrypted communications over unsecured channels. However, WEP protocol has an inherent security flaw. It is vulnerable to the various attacks, various experiments has proved that WEP fails to achieve its security goals. This thesis entails designing, evaluating and prototyping a wireless security infrastructure that can be used with the WEP protocol optionally, thus reducing the security vulnerabilities. We have studied the flaws of WEP and the reasons for their occurrence, and we provide the design and implementation of a novel scheme in Matlab and VHDL to improve the security of WEP in all aspects by a degree of 1000. The architecture was designed with a consideration for least increment in hardware, thus achieving power and cost efficiency. It also provides flexibility for optional implementation with the available technology by being able to be bypassed by the technology, which allows for non-replacement of existing hardware, common on both, the WEP and the proposed protocols, on the fly

IPv6 Network Mobility

Network Authentication, Authorization, and Accounting has been used since before the days of the Internet as we know it today. Authentication asks the question, “Who or what are you?” Authorization asks, “What are you allowed to do?” And fi nally, accounting wants to know, “What did you do?” These fundamental security building blocks are being used in expanded ways today. The fi rst part of this two-part series focused on the overall concepts of AAA, the elements involved in AAA communications, and highlevel approaches to achieving specifi c AAA goals. It was published in IPJ Volume 10, No. 1[0]. This second part of the series discusses the protocols involved, specifi c applications of AAA, and considerations for the future of AAA

Analysis of the latest trends in mobile commerce using the NFC technology

The aim of this research is to propose new mobile commerce proximity payment architecture, based on the analysis of existing solutions and current and future market needs. The idea is to change a Mobile Device into a reliable and secure payment tool, available to everyone and with possibility to securely and easily perform purchases and proximity paymentsThe research leading to these results has received funding by the ARTEMISA project TIN2009-14378-C02-02 within the Spanish "Plan Nacional de I+D+I", and the Madrid regional community projects S2009/TIC-1650 and CCG10-UC3M/TIC-4992

Non-repudiation Service Implementation Using Host Identity Protocol

New types of service usages emerge every day in the Internet. Service usage could be Wireless Local Area Network (WLAN) usage or watching a streamed movie. Many of these services are commercial, so payment is often involved in the service usage, which increases the risk of fraud or other misbehaviour in the interaction. To enhance the secu-rity of both service providers and service users, improvements are needed to the existing procedures. The non-repudiable service usage procedure was developed as part of the TIVIT Future Internet SHOK -project. In this model, the service user and the service provider are bound to the actual service usage with certificates. The charging of the service usage is done using hash chains which are bound to the certificates. Now the service user pays only for the service he or she gets. Time or traffic based charging scheme can be used in the service usage. Evidence is gathered from the service usage to help solve possible conflicts afterwards. An actual implementation based on this model was made using Host Identity Protocol for Linux and RADIUS protocol. RADIUS protocol was used to gather the created evidence of the service usage. The implementation was developed for Linux using C-language. The goal of the implementation was to evaluate the concept in actual use. Performance of the implementation was measured with various real use scenarios to evaluate the feasibility of the implementation. Results indicated that the performance of the model is sufficient to serve several simultaneous users. However, the architecture of Host Identity Protocol for Linux caused some performance issues in the implementation
