Abstract: Due to more overhead of asymmetric cryptosystems, traditionally, the symmetric cryptosystem is used to encrypt large messages. But the key management, i.e., the key should be available at both sender and receiver before communication is the most difficult part of symmetric cryptosystem. So, to encrypt large messages, we usually take the help of both symmetric and asymmetric cryptosystems. In this paper, we proposed an asymmetric cryptosystem for encrypting large messages, which is not only efficient but also secure as compared to other asymmetric cryptosystems. In consideration of the aspect of efficiency and computation, our proposed scheme uses elliptic curve cryptosystem.
