Abstract

Abstract: Aiming at the problem that trust management puts emphasis on trust in Public Key Infrastructure(PKI) cross-domain scheme, the trust calculation is discussed under PKI. To adapt the dynamic changes in inter-domain trust features of PKI, a calculation method of PKI cross-domain trust is proposed, which makes the trust evaluation for foreign entities, after the resource domain sets trust relationships between the domain and external root CA, monitor behavior of external users is conducted. The calculation can evaluate the trust entities.

Key words: trust relationship, trust network, resource domain, Public Key Infrastructure(PKI)

摘要： 针对PKI跨域方案中信任管理偏重身份信任的问题，对PKI下的信任计算进行探讨，为适应域间信任关系动态变化的特点，提出一种基于PKI安全域的跨域信任计算方法，该方法结合PKI的身份信任网络，能够使资源域在设置与外域根CA的信任关系，并监控跨域用户行为后，对外域各信任实体做出合理的信任评价。
