We hope to give the busy engineer a quick understanding of the basic concepts of cryptography and a relatively fast way to integrate security in his/her design. Cryptography: Why Do We Need It?

To achieve the goal of data privacy, cryptography falls into three basic categories: symmetric (or single-key) encryption, asymmetric (public-key) encryption, and hash functions.

Description: Introduces the basic concepts of cryptography. Various cipher systems are presented, including transposition and substitution systems, Block ciphers, RSA, and Knapsack. Methods used to ...

To teach his kids about cryptography, [Michal Zalewski] therefore decided to bring the topic to life by building a handheld encryption system, called the CryptMaster 2001.

The concept of cryptography touches our lives many times per day, and that’s probably a conservative estimate. We have a pretty good idea of how it works, having dealt with public-key cryptog… ...
