ePrint Report: Rebound Attacks on SKINNY Hashing with Automatic Tools

Jian Guo, Shun Li, Guozhen Liu, Phuong Pham

In ToSC'20, a new approach combining Mix-Integer Linear Programming (MILP) tool and Constraint Programming (CP) tool to search for boomerang distinguishers is proposed and later used for rebound attack in ASIACRYPT'21 and CRYPTO'22. In this work, we extend these techniques to mount collision attacks on SKINNY-128-256 MMO hashing mode in classical and quantum settings. The first results of 17-round (and 15-round) free-start …
