目前的门限代理签名方案几乎都是基于离散对数问题的,基于RSA密码体制的门限代理签名方案几乎很少。借助简单秘密共享思想构造了一......

提出了一种迭代的有限域平方和算法，每次迭代完成一次比特乘法和模不可约多项式F（x）运算．基于此算法设计出了一种新的串行电路结构．它的......

通过对已有的DES各轮的差分特征进行分析,发现了现有的DES高概率差分特征存在的特有现象,利用这些特点对以前的差分特征搜索算法进......

The trade off between the energy consumption and the quality of the received image should be considered as a main point ......

A cryptosystem based on computation of square roots of complex integers modulo composite n is described in this paper. T......

We study the solvability of two classes of Diophantine equations by using some new methods and new results in this paper......
