基于物理学的密码体制

Cryptography based on physics

本文综述了基于混沌动力学的混沌加密体制，基于量子物理学的量子加密体制，基于光学信息处理的光学模式识别加密体制。对这３ 种加密体系所对应的物理效应、加密原理、特点、研究状况及应用情况做了详细阐述，并分别对３ 种加密体系的发展进行了展望。

In this paper,physical cryptography is discussed,including three cryptosystem:cryptosystem based on optics patten recognition,cryptosystem based on chaotic dynamics,and cryptosystem based on quantum physics.We present a detail description for the physical cryptosystem with the corresponding physical principle,encryptotion principle,applications and their development.
