Specifies a key management system based on a terminal key whose value is dependent on the Message Authentication Code (MAC) residues of previous transactions. The system allows for a new set of transaction keys, including a MAC key and a PIN encryption key, to be generated for each transaction; thus dispensing with the need for fixed keys in the terminal.
