摘要
信任管理是一种适用于大规模的、开放的分布式系统的授权机制。信任管理问题方面包括形式化安全策略和安全凭证,决定是否特定的凭证集合是否可以满足相关的策略以及委托信任给第三方。在信任管理问题中一致性证明是关键而证书链发现问题又是一致性证明的关键。对信任管理中证书链发现问题进行研究,分析了证书的存储和证书链发现算法并指出证书链发现的研究方向。
Trust management is an authorization mechanism for large-scale ,open-distributed systems.Aspects of the trust management problem include formulating security policies and security credentials,determining whether particular sets of credentials sat- isfy the relevant policies,and deferring trust to third parties.Proof of compliance is a key problem in trust management problems, and certificate chain discovery is a key problem in proof of compliance.In this paper,the research on certificate chain discovery is described,certificate storage and certificate chain discovery algorithm are analyzed,future development directions about certificate chain discovery is pointed out.
