Design and Simulation of Mobile Commerce Identity Authentication Protocol Based on OTP

With popularization and development of mobile commerce, the security of mobile commerce has drawn more and more attentions. Identity authentication is the first safety barrier, as communication security almost starts from its handshake process. Authentication protocol based on ciper technology is the safest method to realize identity authentication, and therefore identity authentication protocol is necessary to ensure communication security in mobile commerce. Combined One-time password (OTP) with Elliptic Curve Cryptosystem (ECC), a mobile commerce identity authentication (MCIA) protocol is presented. The two procedures of user registration and bidirectional authentication are designed. In order to verify its operation efficiency in the actual network environment, the simulation model of MCIA is set up through Opnet. The MCIA performance is analyzed from the statistics variables, including scheme time, server queuing delay, channel utilization and throughput. The results verify that MCIA has better feasibility in mobile commerce environment. Design and Simulation of Mobile Commerce Identity Authentication Protocol Based on OTP
