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. Fin...
