Caifen Wang · Jisuanji gongcheng · 2012
In Zhao's network coding signature verification scheme,the adversary can forge the new message by using legitimate messages,which can be verified in verification process,so that pollution attack is successfully conducted.Aiming at the shortcoming in signature and verification process,by adding a computing element in the verification formula,the scheme can prevent attacker forging messages to resist pollution attack and enhance the security of the scheme.
