Abstract
A hash value generating device for generating a hash value based on the KECCAK algorithm includes a θ processing unit, a ρ processing unit, a π processing unit, a χ processing unit, and anprocessing unit for performing processing of five steps θ, ρ, π, χ, andincluded in round processing of the KECCAK algorithm. The π processing unit receives input of data in units of planes and outputs data in units of sheets.
