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...

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...

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...
