摘要：
In [2] a public key encryption scheme was proposed against adversaries with a bounded number of decryption queries based on the decisional Diffie-Helman Problems. In this paper, we show that the same result can be easily obtained based on weaker computational assumption, namely: the computational Diffie-Helman assumption.
