This article describes the S-box used by the Rijndael (aka AES) cryptographic algorithm.The S-box is generated by determining the multiplicative inverse for a given number in Rijndael''s finite field (zero, which has no inverse, is set to zero).In cryptography, the Advanced Encryption Standard (AES) is an encryption standard adopted by the U.S. government.

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. This article describes the S-box used by the Rijndael (aka AES) cryptographic algorithm.The S-box is generated by determining the multiplicative inverse for a given number in Rijndael''s finite field (zero, which has no inverse, is set to zero).In cryptography, the Advanced Encryption Standard (AES) is an encryption standard adopted by the U.S. government. The standard comprises three block ciphers, AES-128, AES-192 and AES-256, adopted from a larger collection originally published as Rijndael. Each of these ciphers has a 128-bit block size, with key sizes of 128, 192 and 256 bits, respectively. The AES ciphers have been analyzed extensively and are now used worldwide, as was the case with its predecessor, the Data Encryption Standard (DES).
