Chameleon-Hashes with Dual Long-Term Trapdoors and Their Applications
A chameleon-hash behaves likes a standard collision-resistant hash function for outsiders. If, however, a trapdoor is known, arbitrary collisions can be found. Chameleon-hashes with ephemeral trapdoors (CHET; Camenisch et al., PKC 17) allow prohibiting that the holder of the...
