Bit-Sliding: A Generic Technique for Bit-Serial Implementations of SPN-based Primitives -- Applications to AES, PRESENT and SKINNY
Bit-serial implementations bit-slide lightweight cryptography
2017/6/26
Area minimization is one of the main efficiency criterion for lightweight encryption primitives. While reducing the implementation data path is a natural strategy for achieving this goal, Substitution...
