| 摘 要： | 组合公钥算法中存在选择共谋攻击、随机共谋攻击和线性分析共谋攻击.本算法中用户的私钥是基本私钥与辅助私钥的逆元模乘的结果,基本私钥与辅助私钥分别由基本私钥矩阵和辅助私钥矩阵中的元素组合生成,用户的私钥间不存在线性关系.经过分析,本算法可以抵抗组合公钥算法中存在的选择共谋攻击和随机共谋攻击,并且辅助密钥矩阵的大小可以根据需...

| Abstract: | There are choice collusion attack,random collusion attack and linear collusion attack in CPK.The user's private key of this algorithm was generated by multiplying the basic private key with the inverse of the assistant private key.The basic private key and the assistant private key was the result of combining the elements of the basic private key matrix and the assistant private key matrix separately.The relationship among user's private keys is nonlinear.By analyzing,this algorithm can defend from the choi... |
