Implementation in one FPGA of the AES-Rijndael in Offset Codebook (OCB) and Electronic Codebook (ECB) modes of operation was developed and experimentally tested using the Insight Development Kit board, based on Xilinx Virtex II XC2V1000-4 device. The circuit was designed to provide simultaneous data privacy and authenticity in applications which require(More)
This paper presents an architecture for the trace-back unit of a Viterbi decoder, whose decoding window length can be adjusted dynamically during runtime, allowing power to be saved by turning off the unused stages. Power savings of up to 62% are reported, using two different technology libraries to validate the results. An algorithm is also provided, which(More)
