可信度共享认证模型研究

由于认证系统存在不确定性，本文给出认证可信度的相关概念以描述不确定性，并给出多认证机制下可信度共享认证模型。该模型在可信度共享的思想上，通过将系统访问可信度值在多认证机制之间的分散管理，防止特殊场合认证机制的权力过于集中，以满足重要系统的特殊需要，增强系统的安全性。

Research on the Trustworthiness Sharing Authentication Model

Because the authentication systems have several uncertainties, this paper gives the related concepts of Authentication Trustworthiness to describe the uncertainties, and gives the trustworthiness sharing authentication model under the condition of multiple authentication mechanisms. Based on the thought of trustworthiness sharing, by decentralizing the management of system access trustworthiness among multiple authentication me[JP2]chanisms, the model can prevent the authentication mechanism with too many rights, and satisfy the special requirements of important systems, and improve their security.
