Abstract:

Because the authentication systems have several uncertainties, this paper gives the related concepts of Authentication Trustworthiness to describe theuncertainties, 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 mechanisms, the model can  prevent the authentication mechanism with too many rights, and satisfy the special requirements of important systems, and improve their security.

Key words: （authentication trustworthiness, trustworthiness sharing, authentication model）
