摘要
随着科学技术的迅猛发展,人们对信息安全和保密的重要性认识不断提高,在信息安全中起着举足轻重作用的密码学成为信息安全中不可或缺的重要部分,同时它还在社会多个领域发挥着重要作用。因此,密码学顺理成章地成为研究通信安全和保密的重要学科。仿射密码作为密码学中古典密码类的一种,要不断展开学习和研究。分析仿射密码的基本原理,掌握仿射密码实现的关键技术,灵活运用仿射密码加密、解密算法设计。
With the rapid developme, nt of science and technology, the people always attach great importance to information security and confidentiality, and cryptography plays an important and indispensable role in information security, and also in many social areas. Therefore, cryptography naturally becomes the important topic in the research of communication security and confidentiality. Affine cipher, as a classical cipher in cryptography, is uninterruptedly studied and researched. It is necessity to analyze the principle of affine cipher, grasp its key technology, and flexibly apply its encryption/decryption algorithm design.
