Certificateless cryptography is a paradigm in the field of cryptography that aims to address some of the limitations of traditional public key infrastructure (PKI) systems. In traditional PKI, users have a pair of keys: a private key, which they keep secret, and a public key, which they share openly. To bind a public key to an individual, digital certificates issued by a trusted certificate authority (CA) are typically used.
