FPGA Can be Implemented Using Advanced Encryption Standard Algorithm

Author

Abstract

This paper mainly focused on implementation of AES encryption and decryption standard AES-
128. All the transformations of both Encryption and Decryption are simulated using an iterative
design approach in order to minimize the hardware consumption. This method can make it a
very low-complex architecture, especially in saving the hardware resource in implementing the
AES InverseSub Bytes module and Inverse Mix columns module. As the S -box is implemented by
look-up-table in this design, the chip area and power can still be optimized. The new Mix
Column transformation improves the performance of the inverse cipher and also reduces the
complexity of the system that supports the inverse cipher. As a result this transformation has
relatively low relevant diffusion power .This allows for scaling of the architecture towards
vulnerable portable and cost-sensitive communications devices in consumer and military
applications.
