LUT-SHA256: Arithmetic-Free Execution of SHA-256 through Chained Look-Up Tables
This work presents LUT-SHA256, an alternative execution architecture for theSHA-256 compression function in which no arithmetic, logical, or shiftoperation is ever applied to message data. The proposal rests on twostructural theorems: addition modulo 2^32 is reformulated as a fou...
