RFID systems have become vital technology for realizing ubiquitous computing environments. However, features of RFID systems present potential security and privacy problems. In an effort to resolve these problems, many kinds of security and privacy enhancement technologies have been researched. However, solutions produced to date still have flaws and are not sufficiently effective for real RFID systems such as the EPCglobal network (TM). Therefore, in this paper, to make RFID systems more secure and efficient, improved technology based oil password, is proposed. The proposed technology combines ail encryption algorithm with a password-derived key, and can be applied to low-cost RFID systems for enhancing the security and privacy of these systems.

There are many security defects in existing mobile communication systems, such as unidirectional authentication and cipher key transmission in plaintext. With the expansion of the mobile communication services, the mobile security becomes more and more important, but the existing communication systems can not prevent hostile attacks to supply high-quality service because of their defects in security. To solve these problems, we propose a new Security Architecture for Mobile Communication (SAMC), which employs new authentication protocols, chooses different encryption algorithms for different requirements and implements integrity control mechanism. Good security is developed in an open environment with the collaboration of experts. It has the robust security and the outstanding performance, just a slight and acceptable loss.

The number of Internet and wireless communications users has rapidly grown and that increases demand for security measures to protect user data transmitted over open channels. In December 200 1, the National Institute of Standards and Technology (NIST) of the United States chose the Rijndael algorithm as the suitable Advanced encryption Standard (AES) to replace the Data encryption Standard (DES) algorithm. Since then, many hardware implementations have been proposed in literature. We present a hardware-efficient design increasing throughput for the AES algorithm using a high-speed parallel pipelined architecture. By using an efficient inter-round and intra-round pipeline design, our implementation achieves a high throughput of 29.77 Gbps in encryption whereas the highest throughput reported in literature is 21.54 Gbps.

During a field trial performed at the Norwegian telecom company NetCom from May 2003 to July 2003, a methodology for model-based risk analysis was assessed. The chosen methodology was the CORAS methodology (CORAS, 2000), which has been developed in a European research project carried out by 11 European companies and research institutes partly funded by the European Union. The risk analysis and assessment were carried out by the Norwegian research institute SINTEF in cooperation with NetCom. NetCom (***) is one of the main mobile phone network providers in Norway. Their 'MinSide' application offers their customers access to their personal account information via the Internet, enabling them to view and change the properties of their mobile phone subscription. 'MinSide' deals with a lot of sensitive customer information that needs to be secure, while at the same time being easily available to the customer in order for the service to remain usable and competitive. The goal of the analysis was to identify risks in relation to the use of the 'MinSide' application and, where possible, suggest treatments for these risks. This was achieved through two model-driven brainstorming sessions based on system documentation in the form of UML sequence diagrams and data flow diagrams.

Wireless sensor networks are one of the pioneer technologies of the new century. The low cost of these networks makes them applicable to a variety of areas from battlefields and environment monitoring to health and house appliances. A sensor network is composed of a large number of low cost sensor nodes, which are densely deployed for a specific application inside a usually small environment [1]. Unfortunately their low cost restriction imposes a kind of conservative view on resource consumption. Network setup is one of the power consuming procedures in initialization of the network. In the setup stage, the base station constructs the routing table of all nodes. The total energy of network setup is just before the main function of the network, so decreasing this energy helps the network to perform more functions before its energy exhausts. The purpose of this paper is to decrease the overall energy of setup phase in two ways, first Tiny encryption algorithm (TEA) for security purposes, which are essential for any wireless network against adversaries and unauthorized accesses. This encryption algorithm decreases the amount of computations and memory consumptions. Further more, it defines some kinds of groups to decrease the number of message exchanges and amount of traffic and hence the energy consumed Simulation results show our proposed method decreases the total amount of energy consumptions in the setup stage and convergence time of the route table compared to the traditional setup method.

The need for stream ciphers in communication and information cryptographic systems is rapidly grown in the last twenty years. The stream ciphers usually use a pseudo-random number generator with large period, large linear complexity and good statistical properties. At present a small number Of software-oriented stream ciphers are known. Due to this reasons in our paper we suggest a new pseudo random number generator, named P-adic Shrinking - Multiplexing Generator, and give its statistical analysis.

Wireless sensor networking is an emerging technology having a wide range of potential applications. Since most wireless sensors have significantly limited memory capacity and power consumption, we need to implement fast encryption/decryption for real time signal processing with small available memory. The purpose of this paper is to evaluate suitability of Rijndael, selected as Advanced encryption Standard by NIST, for encryption in the case of wireless sensor networks. The performance of Rijndael is compared in terms of the code size and the implementation speed with TEA (Tiny encryption algorithm) which requires a small code size but has security problems. We tested implementation of both algorithms on low power 16-bit microcontroller TI MSP430F149 used in Wireless Sensor Network WISE. According to our experiment, Rijndael requires more code size than TEA but Rijndael is relatively suitable for the wireless sensor networks using 16-bit microprocessors.
