概要

• 論文の詳細を見る

• Recently, Camenisch et al. and Fischlin proposed provably secure signature schemes in the standard models respectively. In this letter, we propose key substitution attacks on these two signature schemes. We show that an adversary can generate a valid public key corresponding to a legitimate signature.
