Logical channel number according to 1. There are two types of digital signatures:. Views Read Edit View history. The following additional rule is defined for linear structures and for cyclic structures: The last possible position of a control reference template is just before the first data object to which the referred mechanism applies. SM data objects incorrect.

The trailer codes the status of the receiving entity after processing the command-response pair.
For example, the last possible position of a template isk cryptographic checksum is just before the first data object integrated in the computation. Created inupdated in Retrieved 19 April Consequently, the body is empty. Valued to 0 for the first data unit of the EF, the offeset is incremented by 1 for every subsequent data unit. This clause defines 3 types of SM-related data objects: Entity authentication with key — The entity to be euthenticated has to prove the knowledge of the relevant key in an authentication procedure e.
ISO/IEC 7816-4:2013
Short EF identifiers connot be used in a path or as a file identifier e. The FCI template is intended for conveying file control parameters and file management data. The length Le is also null; therefore the Le field is empty.
The order of the file identifiers is always in the iecc parent to child. In any command using secure messaging the following specific error conditions may occur: Between those two identifiers, the path consists of the identifiers oso the successive parent DFs if any.
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 computation of a digital signature related data objects.
The loaded data may contain, for example, code, keys ios applets. The following additional rules are defined for linear structures and for cyclic structures: The transmission and reception of data fields may be interleaved with the execution of security mechanisms. This clause contains information on the logical structure of data as seen at the interface, when processing interindustry commands for interchange.
Each command message may carry a response descriptor template fixing the data objects required in response. If the response descriptor provides auxiliary data, then the respective data object shall be empty in the response.
The parameter bytes P1-P2 of a command may have any value. When there is no current record, the next occurrence shall be equivalent to the first occurrence. It encodes a class, a type and a number. The following additional rule is defined for linear structures and for cyclic structures: The present specifications of the padding rules do not preclude such a feature. Identification of persons using biometric methods is outside the scope of this standard.
It is an unsigned integer, limited to either 8 or 15 bits according to an option in the respective command. The status bytes SW1-SW2 of a response denote the processing state in the card. An application protocol data unit APDU contains either a command message or a response message, sent from the interface device to the card or conversely.
The initial data reference, when applied to cryptographic checksums, fixes the initial check block. It codes no class and no construction-type.

In case 1, the body of isl command APDU is empty. The first byte of the value field is named the type cryptogram descriptor byte and is mandatory. In case 2, the length Lc is null; therefore the Lc field and the data field are empty.
