Rijndael Architectures and Implementations

On the 2nd October 2000 the US NIST selected the Rijndael algorithm, developed by Joan Daemen and Vincent Rijmen [56], as the new Advanced Encryption Standard (AES) algorithm. It proved a fast and efficient algorithm when implemented in both hardware and software across a range of platforms. In November 2001, the AES was approved as the Federal Information Processing Encryption Standard (FIPS 197) and it is to be employed by government agencies and the private sector to encrypt sensitive, unclassified information [57]. In the future Rijndael will be the encryption algorithm used in many applications such as: Internet RoutersRemote Access ServersHigh Speed ATM/Ethernet SwitchingSatellite CommunicationsVirtual Private Networks (VPNs)SONETMobile phone applicationsElectronic Financial Transactions
