A new CCA-secure encryption based on the Gap Hashed Diffie-Hellman problem
This paper proposes a variant of the ElGamal public key encryption which is secure against chosen ciphertext attack. Our proof of security is based on the intractability of the Gap Hashed Diffie-Hellman assumption in the standard model. The proposed scheme is practical to send encrypted short mess...
