摘要：Focusing on multi-machine distributed computing security problems in cloud computing, the paper has proposed a grid distributed parallel authentication model based on trusted computing, which can realize simultaneous verification of grid authentication and grid behavior on upper layer of SSL and TLS protocols. Adaptive grid authentication method is established applying adaptive stream cipher framework; an adaptive stream cipher heuristic code generator and k-means heuristic behavior trust query function is proposed and acted as authentication kernel. Through comparison of the test results of TLS and SSL authentication protocol and the new grid authentication method, the effectiveness of the new grid authentication method has been explained.
