In this paper, we present a new identity-based encryption IBE scheme using bilinear pairings. Compared with the famous IBE scheme of Boneh and Franklin, ours is more practical in the multiple private key generator multiple-PKG environment. We prove that our scheme meets chosen ciphertext security in the random oracle model, assuming the intractability of the standard bilinear Diffie-Hellman problem.
