Abstract: | The first practical identity based encryption (IBE) scheme was published by Boneh and Franklin at Crypto 2001, based on the
elliptic curve pairing. Since that time, many other IBE schemes have been published. In this paper, we describe a variant
of Boneh-Franklin with a tight reduction in the random oracle model. Our new scheme is quite efficient compared to existing
schemes; moreover, upgrading from Boneh-Franklin to our new scheme is straightforward.
