According to its abstract, it specifies a card application. NOTES An EF of record structure may support data unit referencing and in case it does, data units may contain structural information along with data, e.
For example, the last possible position of a template for cryptographic checksum 781-65 just before the first data object integrated in the computation.

Figure 1 illustrates 786-5 example of the logical file organization in a card. The following two types of EFs are defined: Figure 1 — Logical file organization example.
Between those two identifiers, iiso path consists of the identifiers of the successive parent DFs if any. Consequently, the body consists of the Lc field followed by the data field.
The length field consists of 1 or 3 consecutive bytes. There are two types of digital signatures:. It is an unsigned integer, limited to either 8 or 15 bits according to an option in the respective command.
Each non TLV-coded data field shall consist isk one or more data elements, according to the specifications of the respective command. Figure 4 shows the 4 structures of command APDUs according to the 4 cases defined in table 4. An annex is provided that shows how to control the loading of data secure download into the card, by means of verifying the access rights of the loading entity and protection of the transmitted data with secure messaging.

Entity authentication with key — The entity to be euthenticated has to prove the knowledge of the relevant key in an authentication procedure e. If a card supports the logical channel mechanism, then the maximum number of available logical channels is indicated in the card capabilities see 8. Organization, security and commands for interchange”.
Within each EF of cyclic structure, the record numbers shall be sequentially assigned in the opposite order, i.

Retrieved from ” https: The length Le is null; therefore the Le field is empty. Short EF identifiers connot be used in a path or as a file identifier e. Therefore a spcecific response corresponds to a specific command, referred to as a command-response pair. Learn more about the cookies we use and how to change your settings.
If the auxiliary data is less than k bytes, then it is headed by bits set to 0, up to the block length. Referencing by file identifier — Any file may be referenced by a file identifier coded on 2 bytes.
In any command using secure messaging the following specific error conditions may occur: The last possible position of a control reference template is just before the first data object to which the referred mechanism applies.
ISO part 4 section 5 APDU level data structures
The security attributes of file depend on:. There are two types of digital signatures: The security attributes, when they exist, define the allowed actions 7186-5 the procedures to be performed to complete such actions. No byte is used for Lc valued to 0 No data byte is present. The response descriptor template, if present in the data field of the command APDU, shall fix the structure of the corresponding response.
Within an EF of record structure, records may have the same record identifier, in which case data contained in the records may isoo used for discriminating between them. Created inupdated in These commands cover the entire life cycle of the card and therefore some commands may be used before the card has been issued to the cardholder or after the card has expired.
It gives the identifier, name, description, format, coding and layout of each DE and defines the means of retrieval of DEs from the card.
In case 4, the length Lc is not null; therefore the Lc field is present and the data field consists of the Lc subsequent bytes.
There shall be independence of activity on one logical channel from activity on another one. Take the smart route to manage medical device compliance.
The previous occurrence shall be the closest record with the specified identifier but in a smaller logical position than the current record. Each control reference remains valid until a new control reference is provided for the same mechanism. In order to select unambiguously any file by its identifier, all EFs and DFs immediately under a given DF shall have different file identifiers. 78116-5 there is no current record, the next occurrence shall be equivalent to the first occurrence.
This clause describes the following features: This clause defines 3 7186-5 of SM-related data objects: You may experience issues viewing this site in Internet Explorer 9, 10 or The card shall support at least one of the following four methods for structuring EFs: The tag field T consists oso a single byte encoding only a number from 1 to e.
If an empty reference data object for auxiliary data is present in the response descriptor, then it shall be full in the response.
Data referencing method, record numbering method and data unit size are EF-dependent features. In the data field, the present SM format may be selected implicitly, i. This part specifies commands for application management in a multi-application environment.
In case 1, the length Isp is null; therefore the Lc field and the data field are empty.
