Abstract :
Recently, in order to eliminate the use of certificates in certified public key cryptography and the key-escrow problem in identity based cryptography, the notion of certificate less public key cryptography was introduced. In this paper, the first certificate less-based chameleon hash scheme is proposed, which does´t suffer from the key escrow problem. Moreover, the proposed chameleon hash scheme can achieve all the desired security notions in the random oracle model.
