In a famous paper of Crypto’01, Boneh and Franklin proposed the first identity-based encryption scheme (IBE), around fifteen years after the concept was introduced by Shamir. Their scheme security (more precisely, the notion of resistance against an IND-ID-CCA attacker) relies in the random oracle model. However, the reduction is far from being tight, and… CONTINUE READING
