VLSI Implementation of Encryption Using Rijndael

VLSI Implementation of Encryption Using Rijndael

Abstract:

Cryptographic algorithms can be efficiently implemented in custom hardware than in software running on general- purpose processors. Implementation of encryption using Rijndael can be done on the proposed design using VHDL, and can be targeted to Xilinx FPGA device. Compared to software implementation, hardware implementations provide more physical security as well as higher speed. In this paper VLSI architectural optimisations such as parallelism and distributed memory are discussed, and several hardware design techniques are employed to increase performance and reduce area consumption. This implementation will be useful in securing data, whenever data is transmitted across an accessible medium (wires, wireless, etc.) and also in the case of electronic financial transactions.
