A Low Power Side Channel Attack Resistant Data Flow Rindael Encryption ASIC

Abstract

THDFAES04 is a data flow random execution Rijndael encryption ASIC, which can resist against side-channel attacks and is low power. It is based on dynamic data-flow architecture. It performs token matching and random service jointly by the token Hold-Match-Fetch components. In experiments, it could resist 15000 less samples correlation power analysis attack. The fabricated chip's average energy of one 128 bits key AES encryption is 0.053 muJ. Its die size is 2.21 mm2. Its throughput distributes between 59 Mbps and 63 Mbps.
