Title:
Secure Identity Based Encryption Without Random Oracles
Authors: Dan Boneh, Xavier Boyen
Abstract: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.
