Secure Identity Based Encryption Without Random OraclesAuthors: D. Boneh and X. Boyen
We present a fully secure Identity Based Encryption scheme whose proof of security does not rely on the random oracle heuristic. Security is based on the Decision Bilinear Diffie-Hellman assumption. The system shows that, in principle, identity based encryption is possible without the random oracle model.
