Specification of the security service applied.
Unique reference number assigned by the security originator to a pair of security header and security trailer groups.
The value shall be arbitrarily assigned, but the same value shall not be used more than once within the same EDIFACT structure, I.e. interchange, group, message or package.
Specification of the scope of application of the security service defined in the security header.
It defines the data that have to be taken into account by the related cryptographic process.
Specification of the type of response expected from the recipient.
Identification of the filtering function used to reversibly map any bit pattern on to a restricted character set.
Identification of the character set in which the secured EDIFACT structure was encoded when security mechanisms were applied.
Identification of the role of the security provider in relation to the secured item.
Identification of the role of the security party.
Name used to establish a key relationship between the parties.
Identification of a party involved in the security process, according to a defined registry of security parties.
Identification of the type of identification used to register the security parties.
Identification of the agency in charge of registration of the security parties.
Name of the security party.
Name of the security party.
Name of the security party.
Sequence number assigned to the EDIFACT structure to which security is applied.
This sequence number is security related and may differ from the identification of the EDIFACT structure that may appear elsewhere. It may be used when sequence integrity is required.
Specification of the type of date and time.
Date of event.
Format is YYMMDD or CCYYMMDD.
Time of event.
Format is HHMMSS ... with up to 9 more digits of precision. A 'Z' as the last character indicates UTC time. (ISO 8601)
UTC (Universal Co-ordinated Time) offset from event time.
Format is HHMM. Shall be prefixed with '-' for negative offsets. (ISO 8601)
