The Rijndael algorithm was officially selected as the Advanced Encryption Standard in 2001 and will replace the DES in all applications, including Smart Card based products. For this kind of platform, a compact, area efficient hardware implementation of the algorithm is highly desirable. This paper describes such an implementation, which we have based on GF(28) finite field decomposition. We present our results from mappings on the STMicroelectronics ASIC technology library and discuss area, timing and power consumption figures.
