摘要:Till today, the study of performance of security protocols of WLAN has been one of research focuses. Whereas, owing to enormous complexity and low efficiency of modeling security protocols, there has been by now no uniform method or technology that can be used generally to simulate and evaluate security protocols, and no simulation system available that can well support research on performance of security protocols. So in view of the status quo, we, in this paper, mainly propose a novel security protocol simulation architecture and a simulation extending method for simulating security protocols of WLAN, and then set up a simulation platform for modeling such protocols based on OPNET, a famous simulation software. Finally, with an instance of extending and simulating a security protocol of WLAN, the validity and the universality of the simulation architecture and the extending method as well as the feasibility and correctness of the simulation platform are demonstrated.
