摘要:

针对无线多跳网络编码的安全性问题,提出了一种融合时间戳和同态签名的安全网络编码方法。在利用基于RSA的同态签名方案抵御污染攻击的基础上,引入时间戳设计新型同态签名方案来抵御网络中的重放攻击,以时间戳为源生成网络编码的随机系数来保证签名的同态性。重点分析了本方案产生随机系数的方式对网络编码解码概率的影响,并建立了攻击模型证明方案可同时抵御网络中的污染攻击和重放攻击。性能分析表明本方案与基于RSA的同态签名方案开销比值接近于1。

Abstract:

A secure network coding method merged with timestamp and homomorphic signature which can solve security issues in wireless multi-hop networks was proposed.The timestamp into RSA-based homomorphic signature scheme was brought and used to produce random coefficients of net it possible to defend pollution attacks and replay attacks simultaneously while maintaining the homomorphic property of the signature.The analysis that mainly focus on was the influence of random coefficients on decoding probability of network coding a security of the proposed scheme.Results indicate that the proposed scheme can defend pollution attacks and replay attacks simultaneously,and the ratio of overhead between RSA-based homomorphic signature scheme and the proposed scheme is approximates 1.

Key words: homomorphic signature, timestamp, pollution attack, replay attack, network coding, wireless multi-hop network
