Efficient Leakage-Resilient MACs without Idealized Assumptions
Francesco Berti, Chun Guo, Thomas Peters, and François-Xavier Standaert
Abstract
The security proofs of leakage-resilient MACs based on symmetric
building blocks currently rely on idealized assumptions that hardly translate into
interpretable guidelines for the cryptographic engineers implementing these schemes.
In this paper, we first present a leakage-resilient MAC that is both efficient
and secure under standard and easily interpretable black box and physical assumptions.
It only requires a collision resistant hash function and a single call per message authentication
to a Tweakable Block Cipher
