一种基于混沌加密算法的保密视频会议方案及实现

摘要

针对目前混沌加密算法重于理论研究的现实,结合 P2P 网络传输结构的安全隐患,以 Windows Peer-to-Peer Networking 平台的 Graph 模块为基础,设计了一种运用混沌加密算法进行通信数据加密的 P2P 保密视频会议方案.方案在 P2P 网络结构采用 CA 机制,在网络传输结构上层采用混沌加密算法以及动态密钥管理,构建视频会议的安全环境.在实现该方案基础上探索了混沌加密算法的可用性.%Focusing on the reality of chaotic encryption algorithms more often appearing in theory, combining with the security risks of P2P network structure, this paper provides a new P2P secure video conferencing solution based on the Graph module of WPPN and a chaotic encryption algorithm. The application of CA mechanism inside P2P network structure and chaotic encryption with dynamic key management on data transmission creates a secure environment for video conference. After the realization of this solution, it probes a fact that the chaotic encryption algorithm is available.
