CHAMP: Cayley HAshing with Matrix Products
arXiv cs.CR0 views
arXiv:2610.04442v2 Announce Type: replace Abstract: Cayley hash functions hash binary strings by representing the bits of the message as elements of a semigroup and multiplying the corresponding elements. This gives Cayley hash functions useful homomorphic properties. Here, we propose CHAMP, a Cayley hash function based on products of 2 by 2 matrices over a finite field, and discuss its security, implementation, and performance.
