Cryptography message
WebStarting with the origins of cryptography, it moves on to explain cryptosystems, various traditional and modern ciphers, public key encryption, data integration, message authentication, and digital signatures. Audience This tutorial is meant for students of computer science who aspire to learn the basics of cryptography. WebPMAC, which stands for parallelizable MAC, is a message authentication code algorithm. It was created by Phillip Rogaway . PMAC is a method of taking a block cipher and creating an efficient message authentication code that is reducible in security to the underlying block cipher. PMAC is similar in functionality to the OMAC algorithm.
