### Paper: Secure Identity Based Encryption Without Random Oracles

Authors: Dan Boneh Xavier Boyen URL: http://eprint.iacr.org/2004/173 Search ePrint Search Google 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 decisional bilinear Diffie-Hellman assumption. Previous constructions of this type incurred a large penalty factor in the security reduction from the underlying complexity assumption. The security reduction of the present system is polynomial in all the parameters.
