一种多源网络编码同态签名算法

A homomorphic signature algorithm for multi-source network coding

文章对多源网络编码中的安全性进行深入的分析,提出一种基于同态函数的多源网络编码快速签名算法来预防多源网络中的污染攻击和背叛攻击。与其他签名长度相同的算法相比,本算法对运算和倍点运算次数更少,算法的验证效率要比其他的基于椭圆曲线的算法更高。

In this paper ,the security of multi-source network coding is analyzed ,and a secure and fast signature algorithm based on homomorphic hash function is proposed to prevent pollution attacks and against attacks in multi-source network coding .This algorithm needs fewer operation times of pairing computations and multiplying points computations than the other algorithms with the same signature length .The efficiency of authentication in this signature algorithm is much higher than those of exist-ing algorithms based on elliptic curve .
