The Zheng-Seberry (ZS) encryption scheme was published in 1993 and was one of the first practical schemes that was considered secure against a chosen ciphertext adversary. This paper shows some problems that the semantic security of the one-way hash variant of the ZS scheme is insecure on some special circumstances. Attempts to modify the ZS scheme resultedon an El-Gamal variant that is provably secure in the random oracle model.
