SHA-2-using-ReVamp

ins_gen.c

This program is used to generate the entire instruction set for implementing SHA-2 512 on ReVamp. It also generates the PIR inputs. The words at each round (Wi) have been initialized to 0 for simplicity, since this does not effect the algorithm.

SHA-2.ins

The instruction set that implements the SHA-2 512 cryptographic hash algorithm using a ReVamp architecture. Generated by ins_gen.c

SHA-2.inp

The PIR inputs. Generated automatically by ins_gen.c

config_data.json

Specifies which files are used for instructions and PIR inputs.

revamp.py

ReRam crossbar simulator

sha2ref.c

Reference program used to test the instruction set and PIR inputs. Prints final SHA-2 states in inverted form since the crossbar stores states in inverted form. For simplicity the words at each round (Wi) have been initialized to 0.
