Abstract

Certificateless cryptosystems overcome the key escrow problem in identity-based cryptography. Mediated cryptography allows immediate revocation of public keys. Undeniable signatures limit the public verifiability of ordinary digital signatures. In this paper, we formalize the security models of undeniable signatures in a security-mediated certificateless setting for the first time and put forth the first example of such schemes in the literature. We also prove the security of our scheme under some well-studied assumptions in the random oracle model.
