30、curity framework for telecommunication use of IC cards. This specification does not describe any implementation details. It describes: - a general security approach resulting in a methodology, different card phases for identifying security requirements and a description of security services which ca
31、n 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 of needed security services and a description of a common set of application independent securi
32、ty 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 applications. 2 Normative references This European Standard incorporates by dated or undated reference,

37、ndard, the following definitions apply: 3.1.1 access control information: Information describing for each action which can be performed on a file in the card, the conditions to fulfil. 3.1.2 action: An action performed by an external application on a card means a command followed by a response. Ther
38、e are two kinds of actions: normal actions on files of the card (e.g. Read, Write, Select, Execute, Invalidate, Rehabilitate .), management actions on files of the card (e.g. Create, Delete, Extend.). 3.1.3 application: An application consists of a set of security mechanisms, files, data, protocols
39、(excluding transmission protocols) which are located and used in the IC card and outside of the IC card (external application). 3.1.4 application privilege information: External application capabilities used to perform the rights of the external application. 3.1.5 application provider: The entity wh
40、ich is responsible for the application after its allocation. One application provider may have several applications in one card. The files allocated in the card corresponding to one application are called a card-application. There may exist several applications on a given card from the same applicat
41、ion provider. 3.1.6 card: A multi-application card can be considered as a set of files, some of them shared by the different application provider and/or card issuer, others owned exclusively by application provider or issuer. Files can be read, written or executed. The files located in the card corr
42、esponding to one application provider are called card application.

45、 is the entity which fabricates the card and performs the IC embedding. 3.1.10 external application: Entity, located in the external world, which communicates with the related card application during the session. 3.1.11 external world: All application related entities outside the card. 3.1.12 kernel
46、: Part of the card or external world, which contains application independent datdcode, including the MF (in case of a card kernel) and the operating system. 3.1.13 operating system: That which is required to manage the logical resources of a system, including process scheduling and file management.
47、3.1.14 protocol control information (PCI): Information exchange between application entities using transmission protocols to coordinate the joint operation. 3.1.15 tampering: An unauthorized modification which alters the proper functioning of the card in a manner which degrades the security it provi
