Cayley hashing with cookies

Vladimir Shpilrain, Bianca Sosnovski

Cayley hash functions are based on a simple idea of using a pair of semigroup elements, A and B, to hash the 0 and 1 bit, respectively, and then to hash an arbitrary bit string in…

Cryptanalysis of a Cayley Hash Function Based on Affine Maps in one Variable over a Finite Field

Bianca Sosnovski

Cayley hash functions are cryptographic hashes constructed from Cayley graphs of groups. The hash function proposed by Shpilrain and Sosnovski (2016), based on linear functions ove…

Semi-primitive roots and the discrete logarithm module $2^{k}$

Bianca Sosnovski

We establish a connection between semi-primitive roots of the multiplicative group of integers modulo $2^{k}$ where $k \geq 3$ , and the logarithmic base in the algorithm introduced…
