ISO/IEC 7816
ISO 7816 is a unified multi-part international standard by the International Organization for Standardization and the International Electrotechnical Commission, the essential features of smart cards. The default is an extension to ISO 7810, which specifies the most important physical characteristics of identification cards.
Mid-1980s, it was in the definition of standards mainly to chip cards for phones, with the widespread adoption of smart cards in other industries such as health care were always taken further specifications.
The first three parts of the standards describe the dimensions of the card and its properties such as flexural strength, the position of the electrical contacts on the card, their functions and the electrical signals. Credit cards for phones, whose chip contains no processor, but only use logic, for example, only these three parts and part 10 of the standard.
A number of other parts of the standard (currently part 4-15 ) unify the software engineering properties of operating systems and applications for smart card processor.
ISO 7816 Part 1: Physical Characteristics
Released 1998, Amendment 1 published in 2003
This part describes the requirements for the physical properties of a smart card and the tests to demonstrate the conformity of such a card.
ISO 7816 Part 2: Dimensions and location of the contacts
Released 1999, Amendment 1 published in 2004
Part 2 ( published in 2007 ) defines the permissible configuration of magnetic stripe, chip and instructions for any embossing on the card. In addition, the position and size of the contact areas of the smart card will be described. Again, the methods to be specified to detect the accuracy of the measurements.
ISO 7816 Part 3: Electronic signal and transmission protocols
Published in 1989, revised 1997, amended in 2002 and 2006
With this part all the electrical parameters and the contact-type communication of smart cards can be specified.
The electrical parameters include the power supply, the clock and the reset performance of the smart card and the requirements of the card terminal to the contact card in accordance with specification.
For communication of the physical process is described fundamental and the two data transmission protocols T = 0 ( byte oriented protocol ) and T = 1 ( block- oriented protocol ) defined.
ISO 7816 Part 4: Interindustry commands for interchange
Released 1995, revised and published in 2005, revised and published in 2013
This part of the standard refers to the application layer of the chip card and specifies the file organization, the security structure and the structure of files. In addition, the command structures (see APDU ) and set the commands, including the status words of the chip card. In addition, mechanisms for industrial applications, such as the cryptographically secured communication (see also Secure Messaging ) described.
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 smart cards use unique numbers. For this AID (Application Identification) data structure, and the procedure for the registration of an application and its AID is specified.
ISO 7816 Part 6: Inter -industry data elements for interchange
Released 1996, revised and published in 2004
The part 6, the definition of data objects includes data structure (TLV ) structure and the operations for reading these data items 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 the ajar to SQL language to access the database in a smart card.
ISO 7816 Part 8: Security related inter- industry commands
Published in 1999, revised and published in 2004
In Part 8 Functions and commands are specified, which are sichherheitsrelevant. It includes the secure communication (See Secure Messaging ), digital signature, hash and MAC computation and encryption and decryption of data.
ISO 7816 Part 9: Enhanced inter- industry 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 the file access control and
- Commands to create, find, and delete files on the smart card.
ISO 7816 Part 10: Electronic signal and answer to reset for synchronous cards
Released 1999
Part 10 specifies the electronic parameter, and the structure of the ATRs for memory cards. It is thus the counterpart to part 3 of ISO 7816, which defines these properties for smart cards.
ISO 7816 Part 11: Personal verification through biometric methods
Released 2004
The part 11 describes commands for biometric user identification and the necessary data elements. It involves the transfer of data to the smart card and a possible schedule for the review of these data in identifying a person.
ISO 7816 Part 12: Cards with contacts - USB electrical interface and operating procedures
Released 2005
This portion operates as a new USB contact interface of the IC card. Here are the two options can be specified:
- USB interface in addition to the interface described in part 3.
- USB smart card without interface under Part 3
Currently (July 2008) is the interface been described, but no cards with USB interface on the market are still available.
ISO 7816 Part 13: Commands for application management in multi -application environment
Released 2007
The part 13 contains the command for the management of card applications on a multi-application smart card. The commands cover the entire life cycle of an application on a multi-application smart card and can also be used after personalization and output to the cardholder.
ISO 7816-13 has taken over the structures and methods of the Global Platform specification. This command defines and structures for loading, installing and deleting applications to multi-application cards like Java Card. In addition, secure messaging, protocols and application privileges are defined.
ISO 7816 Part 15: Cryptographic information application
Released 2004
Basis of this part is the standard PKCS # 15, based on which the necessary data elements are defined for a signature card. Which comprises the directory structure and signature files on the smart card.
