Recently Cash, Kiltz, and Shoup [13] showed a variant of the Cramer-Shoup (CS) scheme [14] whose chosen-ciphertext (CCA) security relies on the computational Diffie-Hellman (CDH) assumption. The cost for this high security is that the size of ciphertexts is much longer than the CS scheme (which is based on the decisional Diffie-Hellman assumption). In this paper, we show how to achieve CCA-security under the CDH assumption without increasing the size of ciphertexts. We also show a more efficient scheme under the hashed Diffie-Hellman assumption. Both of our schemes are based on a certain broadcast encryption (BE) scheme while the Cash-Kiltz-Shoup scheme is based on the Twin DH problem. Of independent interest, we also show a generic method of constructing CCA-secure PKE schemes from BE schemes.
