This specification does not describe any implementation details. It describes: a general security approach resulting in a methodology, different
39、card phases for identifying security requirements and a description of security services which can be offered by the IC card; the implementation of the general security approach to the application independent IC card, resulting in a list of application independent security requirements, a selection
40、of needed security services and a description of a common set of application independent security mechanisms; the implementation of the general security approach to applications using IC cards, resulting in a methodology which is used to design the set of security mechanisms for specific application
