A Study On Communication Mechanism Of Mobile Agent System

Because of characteristic of mobile agent calculate mode, mobile agent technology have wide application prospects. Communication is one of indispensable services in mobile agent system. Communication security, communication efficiency, influence mobile agent system security and efficiency.The existing communication mechanisms can be ensured in the security respect, but each there is pro and cons on efficiency. This dissertation provides a communication mechanism with a set of solutions to deficiency on communication efficiency of the already existing communication mechanism. The communication mechanism combined symmetrical key encryption technology with asymmetrical key encryption technology. This communication mechanism can improve the efficiency of communication on the whole on the basis of safety.One important factor that the communication mechanism is used to improve communication efficiency is how to get the parameter S value. According to specific communication data amount, the parameter S determine to use communication mechanism with symmetrical key encryption or communication mechanism with asymmetrical key encryption. Thus use the most suitable communication mechanism on a certain specific communication data amount. This dissertation provide mathematics model that can get the value of parameter S, and two algorithms that can compute the value of parameter S, It' s effectively to use the parameter S to select communication mechanism.
