A method is disclosed for generating time invariant (constant) cryptographic keys. These keys may be used as terminal master keys, secondary communication keys and secondary file keys in the operation of a cryptosystem. By using a host processor cryptographic operation, the system master key is exploited in such a way that the produced keys depend on two independent random values; a user supplied value (RN) and a system supplied master key (KM).
