In block codes, the data comprises of a block of data of a definite length. However, in convolutional codes, the input data bits are not divided into block but are instead fed as streams of data bits, ...

Abstract: SM4, a proposed commercial block cipher to be used in IEEE 802.11i standard ... This countermeasure is based on Boolean matrix product masking which is a provable security masking scheme and ...

This paper proposes a block cipher based on Boolean matrix theory and bit level permutation operations. The cipher is so designed that it can be implemented in hardware and software.
