Executive Summary

To simplify the complex certificate management in the traditional Public Key Cryptography (PKC), Shamir proposed the concept of IDentity-based Public Key Cryptography (ID-PKC). In ID-PKC, there is no need of the certificate of a public key since the user's public key is his identity such as e-mail address, telephone number et al. However, ID-PKC inherently has the key escrow problem, i.e., the key generation center (KGC) knows the user's private key. To solve the problem, Al-Riyami et al. introduced the concept of the CertificateLess Public Key Cryptography (CLPKC).
