Abstract
To provide the confidentiality of messages transmitted over the network, the use of cryptographic system is increasing gradually and the hybrid cryptosystem is widely used. In this paper, we propose a new hybrid cryptosystem capable of providing implicit authentication for the sender’s identity by means of the 1-pass key agreement protocol that offers mutual implicit key authentication, the hash function, pseudo random number generator and the symmetric cryptosystem. Also, we describe some examples such as the Diffie-Hellman based system and the Nyberg-Rueppel based system. The proposed hybrid cryptosystem is more efficient than general public key cryptosystems in the aspect of computation work and provides implicit authentication for the sender without additional increase of the communication overhead.
