基于可信度的网络接入补救机制

Remedy Mechanism for Network Access Based on Trustworthiness

可信计算组织TCG针对不符合可信网络接入策略要求终端的处理问题提出隔离补救的概念,实现终端和网络的可信增强,但在实现模型和运行机制方面的研究还有待完善和加强。提出基于可信度的网络接入补救机制,首先通过可信度计算实现终端的可信程度量化分析,然后进行相应的补救处理操作,最后通过实验分析证明该机制能有效实现终端的隔离与补救,在保证安全性的同时增强了网络的易用性。

The concept of isolation and remedy on endpoint, which is not in conformity to the trusted access policy, is proposed by TCG to realize trusted improvement of endpoint and network. However, how to get the effective remedy model and mechanisms is still a problem. Thus a remedy mechanism for network access based on trustworthiness is put forward in this paper. First, the quantitative analysis of trusted grade is realized through trustworthiness algorithm, and then corresponding remedy operations are done. Finally, experiment and analysis indicates that the proposed mechanism could realize isolation and remedy effectively and ensure both the security and practicability of the network.
