Advanced Encryption Standard Advanced Encryption Standard Questions and Answers A five page fact sheet from NIST over the Advanced Encryption Standard. Read the Article The Advanced Encryption Standard (Rijndael) The block cipher Rijndael is designed to use only simple whole-byte operations. Also, it provides extra flexibility over that required of an AES candidate, in that both the key size and the block size may be chosen to be any of 128, 192, or 256 bits. Read the Article Advanced Encryption Standard by Example The following document provides a detailed and easy to understand explanation of the implementation of the AES(RIJNDAEL) encryption algorithm. The purpose of this paper is to give developers with little or no knowledge of cryptography the ability to implement AES. Read the Article AES: The Making of a New Encryption Standard Most people agree that reading through a stack of governmental standards - full of proclamations, legal jargon, acronyms, and technical specifications - is quite laborious. Few information security professionals, however, survive without them. Standards form the backbone of communication systems, describing (if not requiring) the detailed requirements for interoperability. One needs only to consider the Internet to perceive the importance. The Internet Protocol (IP), considered the fundamental network standard, allows millions of computers to communicate. Many other Internet protocols (e.g., TCP, X.509, and IPSec) serve critical roles in specifying how IP packets are controlled, authenticated, and encrypted. Read the Article The Advanced Encryption System (AES) Development Effort: Overview and Update Selecting a single research topic relevant to the information security arena is not as easy as it may seem at first blush. Even though there are many topics and an immense amount of research material to wade through on each, I experienced the same feeling inside when I selected a topic as I do every time I enter my kids' room, which usually looks like a tornado had just passed through, and not knowing where to begin. After some thought, I decided to research and report on a topic that is fundamental to all of information security, cryptosystems, specifically, the Advanced Encryption System (AES) Development Effort headed up by the United States government. Wherever you find a process that protects data, especially data that may travel through public networks, you are bound to find a cryptosystem. Read the Article Who's Who in AES? The main goal in designing any encryption algorithm is security. There are several encryption methods in use today using various algorithms depending on the information being protected. Some are used to protect unclassified but sensitive data and other secret algorithms are used to protect the most highly classified data. This paper is going to introduce the new Advanced Encryption Standard, or AES, the winning algorithm, its competitors, the specifications set forth, and decision making process of NIST.
