SECURITY HEADER

To specify a security mechanism applied to a EDIFACT structure (i.e.: either message/package, group or interchange).

Notes:
1. 0541, if not present the default scope is the current security header segment group and the message body or object itself.
2. 0507, the original character set encoding of the EDIFACT structure when it was secured. If no value is specified, the character set encoding corresponds to that identified by the syntax identifier character repertoire in the UNB segment.
3. S500, two occurrences are possible: one for the security originator, one for the security recipient.
4. S500/0538, may be used to establish the key relationship between the sending and receiving parties.
5. S501, may be used as a security timestamp. It is security related and may differ from any dates and times that may appear elsewhere in the EDIFACT structure. It may be used to provide sequence integrity.

SECURITY SERVICE, CODED

Specification of the security service applied.

0534

SECURITY REFERENCE NUMBER

Unique reference number assigned by the security originator to a pair of security header and security trailer groups.

Notes:
1. 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.

SCOPE OF SECURITY APPLICATION, CODED

Specification of the scope of application of the security service defined in the security header.

Notes:
1. It defines the data that have to be taken into account by the related cryptographic process.

RESPONSE TYPE, CODED

Specification of the type of response expected from the recipient.

FILTER FUNCTION, CODED

Identification of the filtering function used to reversibly map any bit pattern on to a restricted character set.

ORIGINAL CHARACTER SET ENCODING, CODED

Identification of the character set in which the secured EDIFACT structure was encoded when security mechanisms were applied.

ROLE OF SECURITY PROVIDER, CODED

Identification of the role of the security provider in relation to the secured item.

SECURITY IDENTIFICATION DETAILS

Identification of parties involved in the security process.

Dependency Notes:
1. D2(030,040,050) All or none

Security party qualifier

Identification of the role of the security party.

0538

Key name

Name used to establish a key relationship between the parties.

0511

Security party identification

Identification of a party involved in the security process, according to a defined registry of security parties.

Security party code list qualifier

Identification of the type of identification used to register the security parties.

Security party code list responsible agency, coded

Identification of the agency in charge of registration of the security parties.

0586

Security party name

Name of the security party.

0586

Security party name

Name of the security party.

0586

Security party name

Name of the security party.

0520

SECURITY SEQUENCE NUMBER

Sequence number assigned to the EDIFACT structure to which security is applied.

Notes:
1. 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.

SECURITY DATE AND TIME

Security related date and time.

Date and time qualifier

Specification of the type of date and time.

0338

Event date

Date of event.

Notes:
1. Format is YYMMDD or CCYYMMDD.

0314

Event time

Time of event.

Notes:
1. Format is HHMMSS ... with up to 9 more digits of precision. A 'Z' as the last character indicates UTC time. (ISO 8601)

0336

Time offset

UTC (Universal Coordinated Time) offset from event time.

Notes:
1. Format is HHMM. Shall be prefixed with '-' for negative offsets. (ISO 8601)
