Abstract

Certificateless Public Key Cryptography is a scheme that provides security by avoiding the key escrow and eliminating the drawback of identity-based cryptography. Several certificateless models have been proposed to enhance the efficiency and overcome adversaries attacks. In this paper, we survey various public key encryption schemes on certificateless setting with the security model and discuss the performance. Also, we present the generic model of Certificateless Public Key Encryption (CL-PKE) scheme proposed by various authors.
