Abstract

A method of enforcing security settings in a cryptographic system, including: receiving, by the cryptographic system, a first input message associated with a first security setting of a plurality of security settings; performing, by the cryptographic system, a keyed cryptographic operation mapping the first input message into a first output message, wherein the keyed cryptographic operation produces a correct output message when the cryptographic system is authorized for the first security setting, wherein each of the plurality of security settings has an associated set of input messages wherein the sets of input messages do not overlap.
