摘要: 无线链路不稳定和恶意节点不合作等因素会影响移动P2P网络匿名机制的实现。为解决该问题,通过改进移动P2P网络结构,提出一种可以随网络状况自适应变化的NCS-Crowds匿名算法,综合运用假名映射和掩饰流等匿名技术,设计系统架构演进架构下的双向匿名通信机制。理论分析和仿真结果证明,该机制能够根据网络状况在转发成功率和开销代价之间取得较好的折中,实现双向匿名通信。

Abstract: Unstability of wireless link and the noncooperation of malicious nodes disturb the implementation of anonymous communication in mobile P2P networks. To solve this problem, by improving the structure of mobile P2P network, a self-adaptive anonymous algorithm named Network Condition Sensing-based Crowds(NCS-Crowds) is proposed. On this basis, by synthetically using Kna mapping and palliative flows, a mutual anonymous communication scheme based on System Architecture Evolution(SAE) is proposed to protect user’s privacy. Theory analysis and simulation results show that the scheme can achieve expectant anonymity with reasonable overhead.
