  abstract = {A Public-Key System (especially Identity-Based Encryption) is said to be secure if it is proved to be secure
against simulation studies, taking into account the purpose of the attacker and the model used. Among the goals there are
indistinguished IND and semantic goal, regarding the models, we quote Chosen Plaintext Attack (CPA),Chosen Ciphertext
Attack (CCA). Their combination gives INDistinguishability under Chosen Plaintext Attack (IND-CPA), semantic-CPA, semantic-
CCA, IND-CCA. The study considered as strong and concretizing for ideal security is IND-CCA, for the IBE we talk
about IND-ID-CCA (also: semantics-ID-CPA, semantics-ID-CCA, IND-ID-CPA) . This IND-ID-CCA (as well as the others)
belongs to a full domain whose identity to attack is declared in the challenge. This IND-ID-CCA (as well as the others) belongs
to a full domain whose identity to attack is declared in the challenge. A so-called weak type is introduced in 2003 by Canetti
et al [1] and is called selective-ID. In this model, the target identity to be attacked is declared in the beginning that is in the
Setup. It is proved in [2] that the transition from selective ID to a complete domain requires a multiplication by N (produces
a degradation in the security). In spite of this weakness, in Eurocrypt 2004 Boneh and Boyen [2] proposed two crypto systems
under this type, these are the only ones known in the literature drawn up in the same type. The first is a HIBE based on the
DBDHP (Decisional of Diffie and Hellman Problem) problem and under the Commutative Blinding approach it is known by
BB1. While the second is an IBE Under the Exponent-Inversion approach named BB2, it is based on Dq-BDHIP (Decisional q-
Invertible of Bilinear Diffie and Hellman Problem). By combining the idea of the inverse used in BB2 and remaining in the
Commutative Blinding approach,In this paper we will propose our New IBE scheme [5] which will be efficient than BB1 (IBE
version [4]) and even BB2.},
