We introduce integer compositions signatures (ic): a post-quantum, hash-based family of one-time signatures. The proposed scheme explores a connection between hash-based signatures and combinatorics: the authentication path taken from the signature to the public key is determined by a restricted composition of an 9. The family shows improvements over previous schemes like Winternitz: reduced cost, verification in constant time, and the possibility to tweak the signature for either faster signing or faster verification. Keywords: one-time signatures, ots, hash, authentication, post-quantum cryptography, composition, combinatorics.
