A RSA-based Secure Network Coding Scheme Against Multiple Attacks
摘要
The wireless networks suffer from many security issues,such as pollution attacks,eavesdropping attacks and other diverse modes of attacks.To solve this problem,we introduce two parameters-generation identifier and time stamp into the wireless networks,and propose a RSA-based secure network coding scheme against multiple attacks.The scheme uses homomorphism to generate valid signatures for combined messages,so as to reduce the bandwidth consumption of the system.We compare this scheme with the network coding homomorphic signature scheme against inter-generation pollution attacks,and the results show that the cost ratio of the two schemes is close to 1,but the proposed scheme can resist intra-generation pollution attacks,inter-generation attacks and replay attacks at the same time.
