National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical com

In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. Internatio

19、g diverse application domains. ISO/IEC 24727 defines interfaces such that independent implementations are interoperable. Services may be discoverable through mechanisms detailed in ISO/IEC 24727. ISO/IEC 24727 discovery methods include provisions for a client-application to discover card-application
20、s available for selection on the ICC, information about each card-application. ISO/IEC 24727-1 specifies the conceptual framework. It provides essential background information for the subsequent parts. Developers using ISO/IEC 24727 are encouraged to read this introductory part of ISO/IEC 24727. The
21、 other parts provide technical details of the concepts specified in ISO/IEC 24727-1. ISO/IEC 24727-2 details the functionality and related information structures available to the implementation of the interface defined in ISO/IEC 24727-3. ISO/IEC 24727-3 details service access mechanisms to initiate
22、 their use by a client-application. ISO/IEC 24727-4 will detail trust mechanisms and connectivity mechanisms between adjacent components in the communication stack. ISO/IEC 24727-5 will detail test mechanisms. Functionality for ISO/IEC 24727-3 usually resides outside of the ICC. Functionality for IS

36、forming to ISO/IEC 24727. ISO/IEC 24727 defines a set of interfaces and discovery mechanisms such that independent implementations are functionally equivalent as verifiable by testing. ISO/IEC 24727 defines interfaces at two levels between the client-application and a service interface, between a se
37、rvice access layer and a generic card interface. For each specified interface, the relevant parts of ISO/IEC 24727 shall define which functionality shall be supported. ISO/IEC 24727 applies to an ICC providing directly, or indirectly, a capability description. Capability description is described in
38、6.6. INCITS/ISO/IEC 24727-1-20072008 4 ITIC 2008 All rights reserved The service interface, generic card interface, and capability descriptions may be extended according to the future development of ICC technologies. 6 Architecture 6.1 General ISO/IEC 24727 partitions functionality between a client-
39、application running on a host platform and a layered set of services that can be used by a client-application. The organization of services is further defined into a service interface, a generic card interface, and one or more card-applications resident on an ICC. 6.2 Architectural attributes The se
40、rvice interface implements features given in 6.5. The generic card interface implements features given in 6.8. The connectivity interface implements features given in 6.9. The trusted channel interface implements features given in 6.10. Card-applications manage data sets. Each data set is named and
41、the card-application list of data set names is available to the client-application by direct knowledge or discovery. A client-application uses the data set name when requesting a service to be performed on a data set. Access to data sets is controlled through an access control list. The access contr
42、ol list describes the security conditions that shall be satisfied in order to perform an action on the data set. ISO/IEC 24727-3 provides additional detail on access control lists, identities, and actions. Card-applications are organized on an ICC as an alpha card-application and one or more card-ap
43、plications. Card-applications are selectable by AID at the service interface. 6.3 Logical architecture Figure 1 illustrates the relationships between a client-application, the layers and interfaces defined in ISO/IEC 24727, and a card-application resident on an ICC. The flow of requests from the cli
44、ent-application to the card-application is shown as directional arrows indicating either a request or a confirmation. The naming of each arrow conveys functionality being supported by the standard. The actual format and syntax of a request or a confirmation is not detailed in this part of ISO/IEC 24

48、d to establish the communication between the client-application and card-application. Figure 1 shows a stack of layers and interfaces. A proxy is an implementation of the interface of a stack element to allow the stack element implementation to be split. For example, card-application in Figure 1 is
49、a proxy for the actual card. See Annex A for details on the configurations of implementations of the stack. 6.5 Client-application service access layer interface ISO/IEC 24727-3 provides a detailed description of the service interface available to a client-application. An implementation of the service interface translates an action request into one or more generic requests, INCITS/ISO/IEC 24727-1-20072008 6 ITIC 2008 All rights reserved translates one or more generic confirmations into an
