近年来,云计算技术迅速发展,P2P技术在传统网络中也广泛应用.论文将云计算技术和P2P技术有效结合构建云环境下基于混合结构的P2P网络共享模型.P2P技术最重要的安全性是网络节点的通信和隐私保护,云计算技术特殊性对解决云中P2P技术安全性提出新的要求.论文运用可信计算技术、群签名技术及自动信任协商技术提出一种改进的远程自动信任协商证明方案,并把这种证明方案应用到云环境下P2P网络共享模型中用来增强网络节点相互访问的安全性、匿名性和高效性.最后,论文对提出的P2P共享模型进行安全性和效率分析.
In recent years, the rapid development of cloud computing technology, P2P technology is also widely used in traditional networks.This paper combines cloud computing technology and P2P technology to effectively build a cloud-based hybrid P2P network sharing model.P2P technology is the most important security The communication and privacy protection of network nodes and the particularity of cloud computing technology put forward new requirements to solve the security of P2P technology in the cloud.This paper proposes an improved remote automatic trust negotiation using trusted computing technology, group signature technology and automatic trust negotiation Proof scheme and apply this proof scheme to the P2P network sharing model in cloud environment to enhance the security, anonymity and efficiency of mutual access of network nodes.Finally, the paper analyzes the proposed P2P sharing model for security and efficiency analysis.
