FPGA Implementation of Advanced Encryption Standard Algorithm

'DATA' has an important role in the modern world.With the increasing use of computers in a wide range of applications, the amount of data being processed and operated on had increased tremendously over the years. At the same time protection of data during transmission or while in storage may be necessary to maintain the confidentiality and integrity of the information represented by the data. In applications such as storage and transmission of Federal Information, ATM's and in the Internet there is a lot of emphasis for Data Security. This led to the origin of a new field called 'Cryptography' which deals with the DATA and its security.Public key and secret key cryptographic algorithms provide a solution to this security problem.They ensure data authenticity, integrity and confidentiality. The most widely used secret key algorithm at present is Advanced Encryption Standard(AES) Algorithm.AES was considered over, all the other encryption algorithms because of its increased security levels. The work presented in this book deals with the hardware implementation of the AES algorithm which includes writing a Verilog HDL code for the algorithm and synthesizing it on the FPGA board.
