FUNCTION MASKING APPARATUS IN SYMMETRIC CRYPTOGRAPHIC ALGORITHM FOR PREVENTING SIDE CHANNEL ATTACKS AND METHOD THEREOF

摘要

A kind of symmetric key encryption algorithm of masking device function is according to the present invention, side channel analysis is prevented in the function symmetric key encryption algorithm of masking device, have: control unit is included in safety, light weight (HIGHT) algorithm for generating inquiry table and one or more intrinsic functions, based on the multiple nonlinear functions generated at random, multiple linear function, multiple constants; And storage unit, be related to for inquiry table caused by storing include HIGHT built-in functions algorithm. ;The 2016 of copyright KIPO submissions
