Fast Signature for Multi-source Network Coding
Peng Yon · Journal of Chinese Computer Systems · 2013
Because network coding is very vulnerable to pollution attacks,a novel signature scheme for multi-source network coding based on a homomorphic public cryptography is proposed in the paper. This scheme can detect those polluted messages and discard them. What's more,replaying attacks are also infeasible in this scheme by using the serial number of the message generation. This scheme greatly reduces the requirements of computing pow er of the node and the verification time of the node,so it is efficient and suitable for those scenarios w ith low computing capability such as mobile Ad hoc netw orks and w ireless sensor netw orks.
