RSA-based signature scheme for multi-source network coding

Because network coding is very vulnerable to pollution attacks,a novel homomorphic signature for multi-source network coding scheme based on the difficulty of RSA problem is proposed in the paper.It is to prevent pollution attacks and replay attacks.This scheme can prevent malicious modification of data packets and polluted data packets will be discarded by the verifier to ensure the security of the system.Our scheme is specially designed for multi-source network coding.It does not need any extra secure channel and uses the linear calculations,so it greatly reduces the requirements of computing power of the node and the verification time of the node.In addition,the scheme can prevent replay attacks by using the serial number of the message generation.
