A Anonymous Communication Scheme Based On Cryptogram Of Public Key In P2P Model

Anonymous communication system can hide the identities and relations of both communicating sides. It is an important demand and application in information security area nowadays.This paper discusses a anonymous communication scheme based on cryptogram of public key in P2P model. The valuable results of this paper can be presented as follows:1. Analyze a variety of anonymous communication schemes domestic and overseas, especially three anonymous communication technologies (anonymous communication based on rerouting, anonymous communication not based on rerouting and anonymous communication based on broadcasting and group casting).2. An anonymous communication scheme based on cryptogram of public key in P2P model is presented and three important technologies which the scheme is depended on are introduced.3. Design the scheme and achieve the basic function in Java.4. Analyze the function and performance of this system through test in Lab. Demonstrate the feasibility of system and its advantages about security and reveal the shortcomings about performance and the need to improve.
