3.1 Definitions

For the purposes of the present document, the following terms and definitions apply:

access conditions: set of security attributes associated with a file.

application: application consists of a set of security mechanisms, files, data and protocols (excluding transmission protocols).

application protocol: set of procedures required by the application.

card session: link between the card and the external world starting with the ATR and ending with a subsequent reset or a deactivation of the card.

current directory: latest MF or DF selected.

current EF: latest EF selected.

data field: obsolete term for Elementary File.

Dedicated File (DF): file containing access conditions and, optionally, Elementary Files (EFs) or other Dedicated Files (DFs).

directory: general term for MF and DF.

Elementary File (EF): file containing access conditions and data and no other files.

file: directory or an organized set of bytes or records in the SIM.

file identifier: 2 bytes which address a file in the SIM.

GSM, DCS 1800 or PCS 1900 application: set of security mechanisms, files, data and protocols required by GSM, DCS 1800 or PCS 1900.

GSM session: that part of the card session dedicated to the GSM operation.

IC card SIM: obsolete term for ID‑1 SIM.

ID‑1 SIM: SIM having the format of an ID‑1 card (see ISO/IEC 7816‑1 [24]).

Master File (MF): unique mandatory file containing access conditions and optionally DFs and/or EFs.

normal GSM operation: relating to general, CHV related, GSM security related and subscription related procedures.

padding: one or more bits appended to a message in order to cause the message to contain the required number of bits or bytes.

plug‑in SIM: Second format of SIM (specified in clause 4).

proactive SIM: SIM which is capable of issuing commands to the ME. Part of SIM Application Toolkit (see clause 11).

record: string of bytes within an EF handled as a single entity (see clause 6).

record number: number which identifies a record within an EF.

record pointer: pointer which addresses one record in an EF.

root directory: obsolete term for Master File.

SIM application toolkit procedures: defined in TS 11.14 [27].
