Abstract: In this paper, we present some more results about the security of the Kurosawa-Desmedt encryption scheme and a variant of it. We prove that after a modification, those schemes are secure against adaptive chosen-ciphertext attack not only under the decisional Diffie-Hellman assumption in standard model as before but also under the computational Diffie-Hellman assumption in the random oracle model. These results ensure that both the Kurosawa-Desmedt scheme and the variant have similar security merits as the Cramer-Shoup encryption scheme, which is proposed as a standard.
