Certificate-Based Encryption Without Random Oracles

Abstract

We present a certificate-based encryption scheme which is fully secure in the standard model. Our scheme is based on the identity-based encryption scheme of Waters \cite{W05}. Although some generic constructions from IBE to CBE has been previously proposed, they use the Random Oracle heuristic or provide less practical schemes than ours. Finally, we point out that one of the existing generic constructions going from IBE to CBE is flawed.
