摘要
设计公钥体系的混合式P2P网络信任模型。采用层次化管理体系对节点进行认证,公钥体系保障节点间通信的安全性。通过局部信任、推荐信任、全局信任综合考察节点的可信情况。给出了模型的数学实现方法。仿真结果表明,模型能够有效提高节点的交易成功率。
A hybrid structure peer-to-peer （P2P） trust model based on public key infrastructure （PKI） is designed. Hierarchical management system is adopted to authenticate the peers. The security of communications between peers is guaranteed by Public Key Infrastructure （PKI）. The peer＇s reputation is synthetically inspected by local trust, recommendation trust and global trust. The mathematics method to implement the model is given. Simulations results show that the proposed algorithm can provide nodes with high transaction success rate.
