安全通信中的密钥分配教与学

The Teaching and Learning of Key Distribution in Secure Communication

保密信息的安全传输在商业贸易、网络通信、国防军事等领域有着广泛的应用需求,然而信息安全的核心无疑是密码技术,密钥分配与管理又是密码技术的关键。本文阐述了传统密码算法的密钥分配、身份密码体制的密钥分配、基于生物特征的密钥分配、量子密钥分配的常用技术,我们对它们进行了必要的分析和比较教学,达到了教学的目的,并提高了教学效果。

Secure transmission of confidential information has broad application requirements in the fields of commercial trade,network communication,national defense and military, etc.Beyond all doubt,cryptography technology is the core of information security, while key distribution and management is the critical point ofcryptography technology.This paper expounds the common distribution techniques of the traditional key, the identity key,the biometric key and the quantum key.Through necessary analysis and comparison of the techniques,the teaching goal is achieved and the teaching effect is effectively improved.
