Configurations where the SM handles more than one terminal/user card are not fully speci

Further mechanisms may be required to enable these configurations; the necessary security services and mechanisms to provide application and cryptographic security information for the processing of telecommunication transactions. considering several types of SMs at different l

26、ocations in the system and different system configurations. This part of EN 726 allows interaction between the Integrated Circuit Card (IC card) and the SM via the terminal in a way that may be functionally transparent to the terminal and possibly also the network(s). This provides the flexibility t

This part of EN 726 supports IC cards with payment applications following EN 726-5 and all card applications following clauses 4 to 7 of this part of the standard. This part of EN 726 supports IC cards following EN

28、 726-3:1994. Other telecommunication cards which are not in accordance with EN 726, e.g. simple memory cards, may also be supported by the SM described in this part. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications.

The files allocated in the card corresponding to one application are called a card-application. There may exist

36、several applications on a given card from the same application provider or from several application providers 3.1.4 application session a link between the card application part and the external world application part of the same application 3.1.5 application specific command set (ASC) to a DF can be

37、 associated, optionally, an ASC-set (an application specific command set and/or an application specific program). This means that when selecting this application, the general command set is extended or modified by this specific command set. The ASC is valid for the whole subtree of this application
