Identity-Based Chameleon Hash and Applications
Chameleon signatures are non-interactive signatures based on a hash-and-sign paradigm, and similar in efficiency to regular signatures. The distinguishing characteristic of chamel...

Identity-Based Chameleon Hash Scheme without Key Exposure
In this paper, we propose the first identity-based chameleon hash scheme without key exposure, which gives a positive answer for the open problem introduced by Ateniese and de Mede...

Tweaking TBE/IBE to PKE Transforms with Chameleon Hash Functions
We present two transforms to acquire chosen ciphertext security from tag based techniques. The first one requires the separability of underlying primitives. By separability, info...

Efficient hybrid encryption from ID-based encryption
This paper deals with generic transformations from ID-based key encapsulation mechanisms (IBKEM) to hybrid public-key encryption (PKE). The best generic transformation known until...

Short and Stateless Signatures from the RSA Assumption
We present the first signature scheme which is “short”, stateless and secure under the RSA assumption in the standard model. Prior short, standard model signatures in the RSA...
