摘要: 为解决无线网络易遭受污染攻击和窃听攻击以及攻击方式多样化等安全问题,在无线网络中引入代标识符和时间戳2个参数并结合RSA签名方案,提出一种抗多重攻击的安全网络编码方案。利用同态性质对组合消息生成有效签名,以降低系统的带宽消耗。将该方案与抗代间污染攻击的网络编码同态签名方案进行对比分析,结果表明,两者的开销比接近1,但所提方案能同时抵御代内污染攻击、代间污染攻击以及重放攻击。

Abstract: 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.

Key words: secure network coding, pollution attacks, generation identifier, timestamp, signature
