Abstract

KD04 proposed by K. Kurosawa and Y. Desmedt is the most efficient public key encryption scheme provably secure against adaptive chosen ciphertext attack in standard model based on decision diffie-hellman problem. We proposed a simplify version of KD04 which is more efficient than KD04 while still can be proved to be secure against adaptive chosen ciphertext attack in standard model based on decision diffie-hellman problem.

Note: The new scheme is modified from K. Kurosawa and Y. Desmedt's scheme. It is similar to DHIES, while our scheme is provable secure in standard model under the DDH assumption.
