摘要
Zheng和Seberry在1993年提出了一个加密方案,并声称它是选密安全的,但并没有给出具体的证明。本文在CDH假设下证明了它在随机预言模型下是适应性选密安全的。
In 1993, Zheng and Seberry proposed an encryption scheme and claimed that it was chosen cipher-text secure. But they did not give specific proof. This paper proved that, under the CDH assumption, it was chosen ciphertext secure in the random oracle model.
