ABSTRACT
Two parties at a distance who wish to secretly communicate need a secret key to encrypt/decrypt the messages. To obtain the cryptographic key, the parties may agree on the cryptosystem to be used: symmetrical or asymmetrical. The aspect of symmetrical cryptosystems can be divided in two sub-aspects: encryption key distribution and use of an encryption method which is not vulnerable to attacks. This paper presents how we can use the classical method of Automatic Repeat Request-type to secure the procedure of encryption key distribution from Bechmann-Pasquinucci and Peres protocol. Consequently, for the transmission through the physical communication environment, the data are encapsulated in a frame by adding a header and a piece of control information.
