文摘The publish/subscribe （pub/sub） paradigm has asynchronous, loosely-coupled and many-to-many communication properties and is widely used in the application of large-scale distributed computing environment. There is the problem that is mutual trustable between network proxies in terms of pub/sub systems and the problem which is hardly to distinguish accident responsibility while the accident happens in Kerberos based on symmetrical encryption algorithm. A proxy identity authentication algorithm based on RSA encryption is proposed to solve the problem of mutual trust between proxies, and the security of the messages is guaranteed through certificate delegation. The algorithm can distinguish accident responsibility. The feasibility analysis, security analysis and efficiency analysis of the algorithm are carried out.
