Iwo with contacts — Electrical interface and transmission protocols”. The security items algorithms, key and initial data used for processing the data field of a command message may be different from those used for producing the data field of the subsequent response messsage. The first occurrence shall be the record with the 786-5 identifier and in the first logical position; the last occurrence shall be the record with the specified identifier and in the last logical position.

We use cookies to ixo our website easier to use and to better understand your needs. Decoding conventions for Le If the value of Le is coded in 1 or 2 byte s where the bits are not all null, then the value of Le is equal to the value of the byte s which lies in the range from 1 to or ; the null value of all the bits means the maximum value of Le: Cards with contacts — Physical characteristics”.

ISO part 4 section 5 APDU level data structures

The response descriptor template, if present in the data field of the command APDU, shall fix the structure of the corresponding response. The following rules shall apply The card shall fill each empty primitive data object Each control reference template present in the response descriptor shall be present in the response at the same place with the same control references for algorithm, file and key.

The length of Le is not null; therefore the Le field is present. If a card supports the logical channel mechanism, then the maximum number of available logical channels is indicated in the card capabilities see 8.

In the absence of an algorithm reference and when no 78166-5 is implicitly selected for confidentiality a default mechanism shall apply.

The length field consists of 1 or 3 consecutive bytes. Dedicated file DF Elementary file EF The logical organization of data in a card consists of following structural hierachy of dedicated files: Take the smart route to manage medical device compliance. Consequently, the body consists of the Lc field followed by the data field. The present specifications of the padding rules do not preclude such a feature.

Each command message 7816-55 carry a response descriptor template fixing the data objects required 7816- response. In order to select unambiguously by DF name e. Such a command APDU carries no length field. Inside the response descriptor, the security mechanisms are not yet applied: The order of the file identifiers is always in the direction parent to child.

The choice and conditions of use of cryptographic mechanisms may affect 78165- exportability.

BS ISO/IEC 7816-5:2004

Each security mechanism involves an algorithm, a key, an argument and often, initial data. The splitting into data blocks shall be performed in the following way.

Registration of application providers”. Between those two identifiers, the path consists of the oso of the successive parent DFs if any. Each non TLV-coded data field shall consist of one or more data elements, according to the specifications of the respective command.

ISO part 4, section. When numbered, its number is 0. The transmission and reception of data fields may be interleaved 78116-5 the execution of security mechanisms. The path allows an unambiguous selection af any file from the MF or from the current DF. Worldwide Standards We can source any standard from anywhere in the world. If the response descriptor provides auxiliary data, then the respective data object shall be empty in the response.

Referencing by path — Any file may be referenced by a isoo concatentation of file identifiers. 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.

ISO – important industry standard for integrated circuit cards

List of International Electrotechnical Commission standards. This clause describes the following features: Data encipherment — Using secret internal data, the card deciphers a cryptogram received in a data field.

If L in not null, then the ieo field V consists of consecutive bytes. Each data field shall have one of the following three structures.

The security attributes of file depend on: The cryptogram contents reference specifies the content of the cryptogram e. This mechanism may be used for protecting the rights of a provider. The subsequent clauses specify coding conventions for the class byte, the instruction byte, the parameter bytes, the data field bytes and the status byte. The blocking shall be continuous at the border between adjacent data objects to be integrated The padding shall apply at the end of each data object to be integrated followed either by a data object not to be integrated or by no further data object.

The security status may also result from the completion of a security procedure related to the identification of the involved entities, if any, e. The first input is the exclusive-or of the initial check block with the first data block.

There shall be independence of activity on one logical channel from activity on another one.

Each time a reference is made with a record identifier, an indication shall specify the logical position of the target record the first or last occurrence, the next or previous occurrence relative to the record pointer:.
