• 論文抄録(英) / 内容記述: If a cryptographic scheme is resilient to some leakage, its security is guaranteed to be maintained even if secret information, e.g., the secret-key, is partially leaked. Various security models considering leakage-resilience have been proposed. Hard-to-invert leakage (HL) model, a.k.a. auxiliary (input) leakage model, proposed by Dodis et al. in STOC'09 is especially meaningful since it can deal with leakage caused by a function which information-theoretically determines the secret-key, e.g., a one-way permutation. In this paper, we generically construct identity-based signature (IBS) and attribute-based signature (ABS) which are adaptively secure in the HL model. By instantiating them, we give the first concrete constructions of IBS and ABS which are adaptively secure in the HL model under standard assumptions, i.e., the decisional linear assumption.
