Members can download this article in PDF format. In the last two articles, we covered the basic concepts and two basic types of cryptography. In this article, we will look at specific implementation ...

In this chapter we will look at choosing and optimizing cryptographic algorithms, particularly for resource-constrained systems, such as embedded systems. We will look at various strategies for ...

Hashing is a one-way cryptographic function while encryption is designed to work both ways. Encryption algorithms take input and a secret key and generate a random looking output called a ciphertext.

SHA-1 is one of the most prevalent forms of a secure hash algorithm used in the legal and security industry. Now that Professor Xiaoyun Wang and her associates in Tsinghua University and Shandong ...

A replacement for one of the most-used algorithms in computer security has finally been chosen after a competition between cryptographers that ran for five years. The competition was designed to ...
