In the traditional Public Key Infrastructure (PKI), a Certificate Authority (CA) issues a digitally signed explicit certificate binding a user’s identity and public key to achieve this goal. The main goal of introducing an identity-based cryptosystem and certificateless cryptosystem was avoiding certificates’ management costs. In turn, the goal of introducing an implicit certificate-based cryptosystem was to solve the certificate revocation problem. The certificate and pairing based cryptography is a new technology and at present that technology mainly exists in theory and is being tested in practice. This is in contrast to PKI-based cryptography, which has been an established and is widespread technology. New types of cryptographic schemes require new non-standard certification models supporting different methods of public keys’ management, including theirs generation, certification, distribution and revocation. This paper takes a closer look at the most prominent and widely known non-standard certification models, discusses their properties and related issues. Also, we survey and classify the existing non-standard certification models proposed for digital signature schemes that are using bilinear pairings. Then we discuss and compare them with respect to some relevant criteria.
