Analysis And Research On Security Requirements And Policy Of Mobile Agent

The security problems of mobile agent are vital key of mobile agent technology. Based on summery of mobile agent security mechanism and a series of security problems, the dissertation layouts a standardizing secure mechanism and poses a relatively integral mobile agent secure architecture. This dissertation analyzes detailed research about some key technology and security policy, such as secure saving and getting between agents, secure communication between agents and hosts or agent proxy servers, mobile agent self-safe, safe transfer and control and timestamp, MD5, DSA, identity authentication, digital signature etc. The insecure, single problems are resolved gradually, the whole safe framework needs to synthesize the consideration and form further. According to the actual circumstance, the dissertation finds out the most suitablely effective security policy.The main work of this dissertation of follows:1. To give a relatively integral mobile agent secure architecture. To pose some policy as voting of computing result in route security, timestamp technology and so on.2. Pose some models about mobile agent security by new technology of cryptology such as DSA, Kerberos authorization service.3. Based on Java, put forward some secure communication encrpytion algorithm and functions between agents and hosts or agent servers , such as DSA,MD5,Timestamp and so on.
