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

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.
