Definition
Certificateless cryptography is a type of public-key cryptography that combines the advantages of traditional PKI-based public-key cryptography and identity-based cryptography. A certificateless scheme is characterized by two properties: (a) the scheme provides security without the need for a public key to be verified via a digital certificate, and (b) the scheme remains secure against attacks made by any third party, including “trusted” third parties.
Background
Certificateless cryptography was introduced by Al-Riyami and Paterson [1] in a paper that presented examples of certificateless encryption and certificateless signature schemes. Since this paper was published, the concept has been applied to many other areas of public-key cryptography, including key-establishment protocols, authentication protocols, signcryption schemes, and specialized forms of digital signature schemes.
