Abstract
We present a new identity based scheme using pairings over elliptic curves. It combines the functionalities of signature and encryption and is provably secure in the random oracle model. We compare it with J. Malone-Lee´s scheme from the points of view of security and efficiency. We give a proof of semantic security under the decisional bilinear Diffie-Hellman assumption for this new scheme.
