抗污染攻击的移动P2P数据安全分发系统

Secure Data Distribution System Against Pollution Attacks on Mobile Peer-to-Peer Network

摘要: 采用网络编码方法,给出一个改进的抗污染攻击的安全签名机制,使得签名的私钥能随着传输数据包的改变而改变,运用该安全签名机制设计开发一个移动P2P数据分发原型系统S-SymTorrent.S-SymTorrent以抗污染攻击签名机制作为其数据传输的安全控制策略,不仅获得了较高的传输率,而且确保数据分发的安全性.

Abstract: An efficient secure signature scheme against pollution attacks is improved by network coding, which the private key for its signature can be updated along with the change of transmission packet.A system prototype for secure data distribution on mobile peer to peer network, called S-SymTorrent, is designed and implemented by the given improved secure signature scheme.S-SymTorrent system can transform efficiently the data by the signature scheme against pollution attack, and it can guarantee reliable data distribution.
