Self-certified signature scheme from pairings

To overcome key escrow problems and secure channel problems that seem to be inherent to identity-based cryptography, here we propose a self-certified signature scheme (SCS) from pairings on elliptic curves. We also give a security model, and further provide a security proof in random oracle model. The scheme incorporates the advantages of self-certified public keys and pairings. Besides, it can also provide an implicit as well as mandatory verification of public keys.
