抗重播攻击方案的设计与实现

Design and Implementation of Scheme for Avoiding Replay Attacks

重播攻击是一种会对网络信息安全造成很大影响的攻击方法。这篇文章针对重播攻击,设计并实现了一种利用随机数和公钥密钥学的技术来防范攻击的方案。该方案主要以目前比较成熟的公钥密钥学理论为基础,用到了RSA加解密、摘要、数字信封等算法。从可行性分析可以得出结论:本方案可简单、有效地用在工程实现中,是一种开发周期短、效果好的方案。

Replay attack is a method which has lots of bad influences to network information security. A scheme of avoiding replay attacks which utilizes some techniques about Random and Public-Key Cryptography is presented and designed. This scheme is based on the theory of public key cryptography,with some algorithms about RSA,Hash Digest and digital envelop. The scheme can be simply used in some network security project. The period of exploitation is soon and its realization is simple and reliable.
