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 trapdoor...

A chameleon-hash function is a hash function that involves a trapdoor the knowledge of which allows one to find arbitrary collisions in the domain of the function. In this paper, we introduce the noti...

Chameleon hash function is a trapdoor one-way hash func-
tion. The ID-based chameleon hash function was first introduced by Ate-
niese and Medeiros [1]. As discussed by [1], the general advantages o...

Chameleon signatures were introduced by Krawczyk and Rabin, being non-interactive signature
schemes that provide non-transferability. However, that first construction employs a
chameleon hash that s...
