Efficient single-chip implementation of SHA-384 and SHA-512

Abstract

The rapid developments in the communications industry over the last decade have led to an escalation in the amount of sensitive data being transmitted over the Internet. This has resulted in an increased awareness of the need to provide security measures. Authentication is one such security measure. A novel highly efficient single-chip hardware design of the SHA-384 and SHA-512 authentication algorithms is described in this paper. The compact implementation achieves a throughput of 479 Mbits/sec utilising a shift register design approach and look-up tables (LUTs). This is believed to be the first SHA-384/SHA-512 hardware implementation to be reported in the literature.
