An ElGamal-Like Cryptosystem for Enciphering Large Messages
March/April 2002 (vol. 14 no. 2)
pp. 445-446

In practice, we usually require two cryptosystems, an asymmetric one and a symmetric one, to encrypt a large confidential message. The asymmetric cryptosystem is used to deliver secret key $SK$, while the symmetric cryptosystem is used to encrypt a large confidential message with the secret key $SK$. In this article, we propose a simple cryptosystem which allows a large confidential message to be encrypted efficiently. Our scheme is based on the Diffie-Hellman distribution scheme, together with the ElGamal cryptosystem.
