信任关系管理是Peer-to-Peer信任模型的重要部分,在分布式环境中,如何安全存放和访问信任值是一个难以解决的问题。本协议采用可验证的、无可信中心的(k,n)门限密码系统产生系统的公/私密钥,征集k个管理者为系统中的用户生成证书,管理协议为用户提供信任值的匿名存储和访问服务。分析显示协议能极好地抵御各种攻击。
Trust management is an important part of Peer-to-Peer trust model. In a distributed environment, how to safely store and access trust values is a difficult problem to solve. This protocol uses a (k, n) threshold cryptographic system with a verifiable, untrusted center to generate the system’s public / private keys, soliciting k managers to generate certificates for users in the system, and managing protocols to provide users with confidence values Anonymous storage and access services. Analysis shows that the protocol is extremely resistant to various attacks.
