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.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.
