1 Research on Authentication Scheme in Mobile Commerce System

Authentication is the first guard for mobile commerce security, and mobile commerce authentication system is necessary to fulfill the safety requirements of mobile business communications. Combining OTP mechanism with ECC and Hash function, it is presented an identity authentication protocol in mobile commerce based on OP named IAMME (Identity Authentication Mechanism in Mobile E-commerce). IAMME could achieve bidirectional authentication, cipher key agreement simultaneously and can withstand the decimal attacks, off-line dictionary attacks and man-in-middle attacks effectively. Formal analysis method is the most effective method to analyze security attribute of authentication protocol. Through authentication test method based on BAN and strand space, IAMME is proved to be able to attain the goal of data security, identity authentication and data assurance. Meanwhile, based on fuzzy comprehensive evaluation to establish indicators of mobile commerce authentication system, will compare IAMME with other authentication systems, to ensure its advantages. In order to testify the IAMME’ s operation efficiency and performance in the real mobile environment, the simulation model is set up through OPNET to analysis the performance of IAMME from statistical variances like the certification time, delay, channel utilization and throughput. Then it’s compared with static password authentication mechanism and OTP authentication mechanism based on Challenge/Response, proving that IAMME is with good performance that is suitable for mobile commerce authentication.

Based on a variety of indicators options, according to the business needs of QoS hierarchical strategy will enable various existing business more secure, reliable, have better QoS guarantee.  National High-tech R&D Program of China (863 Program)
4 Data Security Transmission Technique in CTCS-3 Train Control System In order to meet China's railway higher security, speed and service needs, and enhance market competitiveness, China plans to increase investment in the construction speed of 350km / h PDL, CTCS-3 train control system will be the main direction of China's future railway development. CTCS-3 train control system is based on GSM-R wireless communications vehicle to achieve two-way transmission of information in one place, RBC to generate driving license train control system. Train control system as a critical train operation control system, in any case are not allowed to system failure. High security , high reliability is the highest CTCS-3 system design principle, CTCS-3 train control system data communications security and reliability requirements are self-evident , DCS data communications networks also should have high self-healing capabilities. However , CTCS-3 train control system in secure communications protection DCS has many special factors to consider, such as: telecommunications transmission of important information related to traffic safety, the huge amount of data, high-speed train moving train inside and outside radio signals and complex traffic environment makes some adverse GSM-R data transmission security factors intensified. The project will be a detailed analysis of safety issues under the premise of these specific environments and applications GSM-R data transmission, and ultimately propose a suitable overall solution for the rational and effective CTCS3 GSM-R train control system for secure data transmission.

5 On the Key Technologies in Seamless Connection between Wireless Sensor Networks and Internet Based on the Applications to the Internet of Things

Seamless connection between Wireless Sensor Networks and the Internet is an important research issue in the area of the Internet of Things. Currently, many researches are conducted on the protocol improvement in physical layer, link layer, network layer and application layer, but seldom on the whole protocol stack that can run on sensor nodes. This project focuses on researching a light weighted TCP/IP protocol that can run on 8-bit embedded system and realize seamless connection of Wireless Sensor Networks and the Internet.
