CSA-ISO/IEC 7816-4

Description / Abstract: This part of ISO/IEC 7816 specifies

- the content of the messages, commands and reponses, transmitted by the interface device to the card and conversely,

- the structure and content of the historical bytes sent by the card during the answer to reset,

- the structure of files and data, as seen at the interface when processing interindustry commands for interchange,

- access methods to files and data in the card,

- a security architecture defining access rights to files and data in the card,

- methods for secure messaging,

-access methods to the algorithms processed by the card.

It does not describe these algorithms.

It does not cover the internal implementation within the card and/or the outside world.

It allows further standardization of additional interindustry commands and security architectures.
