Highly Secure Nonce-based MACs from the Sum of Tweakable Block Ciphers

Show other versions (1)

Tweakable block ciphers (TBCs) have proven highly useful to boost the security guarantees of authentication schemes. In 2017, Cogliati et al. proposed two MACs combining TBC and universal hash functions: a nonce-based MAC called NaT and a deterministic MAC called HaT. While both constructions provi...
