利用算法对智能卡随机数的伪随机改进

Using the algorithm to improve the random number′s randomness of smart card

随着信息技术的发展,智能IC卡在认证、银行、交通等领域得到广泛应用,系统的真随机数的产生及其改进成为人们的研究重点之一。简单论述了真伪随机数的产生方法 ,并对其随机性进行了伪随机方法的改进。测试结果表明,经过算法处理后的随机性得到了较大的提高,完全通过国家商用密码管理局的随机性检测规范的测试。

With the development of information technology, the smart IC（Integrated Circuit） is widely used in authentication,banking, transportation and other fields, the quality of random number used in cryptosystem has become a research focus.This paper briefly discusses the generation method of random number, and improve the randomness by using pseudo-random method. The test results show that, the randomness has improved after processed using algorithm, and it passed the test of the random inspection of state cryptography administration.
