ISO 7816
ISO 7816 is a multi-part international standard of the International Organization for Standardization and the International Electrotechnical Commission , which unifies the essential characteristics of chip cards . The standard is an extension of ISO 7810 , which specifies the most important physical properties of identification cards.
In the mid-1980s, the standard was mainly about smart cards for card phones , with the increasing spread of smart cards in other industries such as B. the health care more and more determinations were made.
The first three parts of the standard describe the dimensions of the card and its properties such as: B. their flexural strength, the position of the electrical contacts on the card, their functions and the electrical signals. For example, prepaid cards for card telephones whose chip does not contain a processor but only logic use only these three parts and part 10 of the standard.
A number of other parts of the standard (currently Part 4–15) standardize the software properties of operating systems and applications for intelligent processor cards .
ISO 7816 Part 1: Physical Characteristics
Published 1998, Amendment 1 published 2003
This part describes the requirements for the physical properties of a smart card and the tests that prove the conformity of such a card.
ISO 7816 Part 2: Dimensions and location of the contacts
Published 1999, Amendment 1 published 2004
Part 2 (published in 2007) defines the permissible arrangements of magnetic strips, chips and any embossing on the card. In addition, the position and size of the contact surfaces of the chip card are described. Here, too, the methods are specified to prove the correctness of the dimensions.
ISO 7816 Part 3: Electronic signals and transmission protocols
Published 1989, revised 1997, corrected in 2002 and 2006
With this part all electrical parameters and the contact-based communication of chip cards are specified.
The electrical parameters include the power supply, the clock frequency and the reset behavior of the smart card and the demands on the card terminal to contact specification according to the map.
For communication, the physical process is basically described and the two data transmission protocols T = 0 (byte-oriented protocol) and T = 1 (block-oriented protocol) are defined.
ISO 7816 Part 4: Interindustry commands for interchange
Published 1995, revised and published in 2005, revised and published in 2013
This part of the standard relates to the application level of the chip cards and defines the file organization, the security structure and the structure of files. In addition, the command structures (see APDU ) and the commands including the status words of the chip card are specified. In addition, mechanisms for industrial applications, such as cryptographically secured communication (see also Secure Messaging ) are described.
The appendix also contains a description of the data structure ( BER - TLV structure).
ISO 7816 Part 5: Numbering system and registration procedure for application identifiers
Published in 1994, revised and published in 2004
Part 5 defines a scheme for the unambiguous identification of national and international applications on chip cards by means of unique numbers. For these AID ( A pplication Id entification) a data structure and the procedure is specified for the registration of an application and its AID.
ISO 7816 Part 6: Inter-industry data elements for interchange
Published in 1996, revised and published in 2004
Part 6 contains the definition of data objects and the processes for reading out these data objects from a chip card .
ISO 7816 Part 7: Interindustry commands for Structured Card Query Language (SCQL)
Released 1999
This part is a supplement to part 4 and defines a database, commands and a language based on SQL for accessing the database in a chip card .
Released in 1999, revised and published in 2004
In part 8, functions and commands are specified that are relevant to safety. It includes secure communication (see Secure Messaging ), digital signature, hash and MAC calculation, and the encryption and decryption of data.
ISO 7816 Part 9: Enhanced interindustry commands
Published in 2000, revised and published in 2004
This standard part is divided into three parts and contains
- the definition of the life cycle of a smart card application,
- Control elements for file access control and
- Commands for creating, searching and deleting files on the chip card .
ISO 7816 Part 10: Electronic signals and answer to reset for synchronous cards
Released 1999
Part 10 specifies the electronic parameters and the structure of the ATR for memory cards . It is therefore the counterpart to Part 3 of ISO 7816 , which defines these properties for chip cards .
ISO 7816 Part 11: Personal verification through biometric methods
Released 2004
Part 11 describes commands for biometric user identification and the data elements required for this. It includes the introduction of the data into the chip card and a possible procedure for checking this data when a person is identified.
ISO 7816 Part 12: Cards with contacts - USB electrical interface and operating procedures
Released 2005
This part introduces USB as a new contact-based interface for the chip card . Both options should be specified:
- USB interface in addition to the interface described in Part 3.
- USB chip card without interface according to part 3.
At present (July 2008) the interface has been described, but no cards with a USB interface are available on the market.
ISO 7816 Part 13: Commands for application management in multi-application environment
Released 2007
Part 13 contains the commands for managing card applications on a multi-application chip card. The commands cover the entire life cycle of an application on a multi-application chip card and can also be used after personalization and issue to the cardholder.
ISO 7816-13 has adopted the structures and methods of the GlobalPlatform specification. This defines commands and structures for loading, installing and deleting applications on multi-application cards, for example using Java Card . In addition, secure messaging , protocols and application privileges defined.
ISO 7816 Part 15: Cryptographic Information Application
Released 2004
This part is based on the PKCS # 15 standard , on the basis of which the necessary data elements for a signature card are defined. This includes the directory structure, files and signatures on the chip card .
