A key management protocol has been described that will allow the Data Encryption Standard (DES) to be integrated into electronic data processing systems for the purpose of obtaining communication security and file security. Several cryptographic keys have been defined that allow the desired key management protocol to be achieved. They are: • Host master key (KMO) • First variant of the host master key (KM1) • Second variant of the host master key (KM2) • Terminal master key (KMT) • Secondary communication key (KNC) • Secondary file key (KNF) • Primary communication key, or session key (KS) • Primary file key, or file key (KF).
