Certificateless chameleon hash scheme based on RSA assumption

Abstract

Certificatelesspublickeycryptography(CL-PKC),doesnotrequiretheuseofthecertificatetoguarantee the authenticity of public keys. It does rely on the use of a trusted third party (TTP) who is in possession of a master key. CL-PKC does not suffer from the key escrow property. Thus, CL-PKC can be seen as a model for the use of public key cryptography.
