Attacks and Defenses in Cryptography

摘要

Attacks and defenses have always been the focus of information security. If some new attacks appear, the corresponding defense methods will be proposed. In particular, cryptography, as a key security technology, has developed in such an offensive and defensive confrontation environment. For classical cryptography and modern cryptography, attack models, attack means, security models, and security properties are given. Furthermore, attack and defense cases are demonstrated to provide a reference for enhancing the security of cryptography algorithms.
