Paper 2024/163 , Shandong University, Northwestern University, State Key Laboratory of Cryptology, Shanghai Jiao Tong University We continue the study of blockcipher-based (tweakable) correlation robust hash functions, which are central building blocks of circuit garbling and oblivious-transfer extension schemes. As results, we first enhance the multi-user tweakable correlation robust notion of Guo et al.
