This paper present an identity-based encryption (IBE) scheme with full security in prime order bilinear groups by using dual pairing vector space. The security of our scheme is based upon decisional linear and three party Diffie-Hellman assumption by adapting the dual system encryption. We obtain a tighter security reduction compared to previous works based on dual system encryption. The loss for security reduction of our scheme is O(q1), where q1 is the number of key queries in Phase 1.
