Cryptography models
WebCryptography is the mathematical foundation on which one builds secure systems. It studies ways of securely storing, transmitting, and processing information. Understanding what cryptographic primitives can do, and how they can be composed together, is necessary to build secure systems, but not su cient. WebCryptography is the process of hiding or coding information so that only the person a message was intended for can read it. The art of cryptography has been used to code …
