Abstract
In this chapter, we start by introducing the Boneh-Boyen IBE scheme [20], which is selectively secure under the DBDH assumption. Then, we introduce a variant version of Boneh-Boyen IBE for CCA security without the use of one-time signatures [28] but with a chameleon hash function [94]. Then, we introduce the Waters IBE scheme [101] and the Gentry IBE scheme [47], which are both fully secure under the C-Type and the I-Type, respectively. The given schemes and/or proofs may be different from the original ones.
