We extend a technique by Hanaoka and Kurosawa that provides efficient chosen-ciphertext secure public key encryption based on the Computational Diffie-Hellman assumption to the identity-based encryption setting. Our main result is an efficient chosen-ciphertext secure identity-based encryption scheme with constant-size ciphertexts under the Computational Bilinear Diffie-Hellman assumption in the standard model.
