HIGH SPEED VLSI IMPLEMENTATION OF AES-RIJNDAEL ENCRYPTION ALGORITHM

The growing of the Internet at the last decade has§led to an increase in the importance of cryptography.§ Internet applications such as electronic commerce§and electronic communication have made cryptography§an essential tool. Data Encryption Standard (DES)§Algorithm had been the standard symmetric key§algorithm for the government of the United States§since 1977. However, the enormous increase in§computational power has made the DES algorithm§obsolete. Therefore, the National Institute of§Standards and Technology (NIST) held a competition to§determine the new standard. Between 15 candidates,§the NIST selected the Rijndael Algorithm as the new§Advanced Encryption Standard (AES) Algorithm to§replace DES. In high-speed data communication§systems, fast data encryption and decryption is very§important. In this book, a very high speed VLSI§implementation of the Rijndael Algorithm is§presented. Both the encryption and the decryption§algorithms of Rijndael are implemented as a single§ASIC. This book will be very useful for anyone who§wants to implement the AES-Rijndael Algorithm as an§FPGA or ASIC. In this book, all the implementation§steps are explained in detail.
