摘要

信任是移动对等(MP2P)网络安全中首要解决的关键技术问题.由于MP2P网络环境与P2P网络环境有本质的区别

因此现有P2P网络信任模型并不适用于MP2P网络环境.本文提出一种适合MP2P网络环境的动态安全信任模型DSTM_MP2P.DSTM_MP2P包括两种方案

一种是针对节点的信任信息已知或部分已知的情况

提出基于节点行为的节点类型识别机制;另一种是针对节点的信任信息未知的情况

提出基于贝叶斯博弈的节点概率选择策略.通过理论分析和实验证明

无论MP2P网络环境如何

DSTM_MP2P模型使得请求节点总是优先连接安全可靠的节点

从而极大地提高了下载成功率.

Abstract

Trust is the most important key issue for Mobile P2P(MP2P) networks security.As the MP2P networks and the P2P networks environments are fundamentally different

the existing trust models for P2P networks are not suitable for MP2P networks.In view of this

a dynamic secure trust model for MP2P networks (DSTM_MP2P) is proposed.DSTM_MP2P is comprised of two schemes.One is node type-identifying mechanism based on node behavior under the situation of the known or part of the known trust information of the nodes.And the other is node probability selection strategy based on Bayesian game under the situation of the unknown trust information of the nodes.The theoretical analysis and experimental results show that whatever MP2P network environment is

a request node under the direction of the DSTM_MP2P model is always first to connect the safe and reliable nodes

which greatly increases the downloading success rate.
