This paper proposes the architecture of the hash accelerator, developed in the framework of the European Processor Initiative.

Abstract
This paper proposes the architecture of the hash accelerator, developed in the framework of the European Processor Initiative. The proposed circuit supports all the SHA2 and SHA-3 operative modes and is to be one of the hardware cryptographic accelerators within the crypto-tile of the European Processor Initiative. The accelerator has been verified on a Stratix IV FPGA and then synthesised on the Artisan 7 nanometres TSMC silicon technology, obtaining throughputs higher than 50 Gbps for the SHA2 and 230 Gbps for the SHA-3, with complexity ranging from 15 to about 30 kGE and estimated power dissipation of about 13 (SHA2) to 26 (SHA-3) mW (supply voltage 0.75 V). The proposed design demonstrates absolute performances beyond the state-of-the-art and efficiency aligned with it. One of the main contributions is that this is the first SHA-2 SHA-3 accelerator synthesised on such advanced technology.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
