Abstract
The Boneh-Franklin IBE scheme has two variations. The first variation, called BasicIdent, is secure against adversaries that are not allowed to make decryption queries. This construction is modified to obtain the second variation, called FullIdent, which is secure against adversaries that are allowed to make decryption queries. The method of conversion uses a transformation originally proposed by Fujisaki and Okamoto in the context of PKE schemes. This conversion works in the random oracle model.
