New secure explicitly authenticated key agreement protocols
Engineering Mathematics Department, Faculty of Engineering, Alexandria University, Alexandria, Egypt
ABSTRACT: A key agreement mechanism is an essential component in any cryptosystem. The established key is later used to encrypt the exchanged data protecting privacy of communications. Authentication is another important requirement in communication systems to allow only authorized users have access to the channel.
