Code indicating the version/release of the ASC X12 standard that is being used
for this specific security structure. The version/release identified for this
segment also applies to any corresponding trailer or security value segment.
This version/release is independent of any other version/release identified in
another security segment at the transaction set or functional group level. This
version/release is independent of the version/release identified at the
interchange or functional group level
Codes (2)
Code specifying the business purpose of the appended assurance to an existing
secured-entity (whether functional group or transaction set); the codes
represent the intention of the business or application that has control over
the assurance originator
Codes (24)
Code specifying the bounds of the text, whether contiguous or not, over which
the computation of the Assurance Token is computed using the defined
methodology of computation and any relevant Assurance Token parameters
The "body" is defined as a transaction set, beginning with the first byte of
the segment immediately following the ST segment terminator and including all
segments up to but not including the "S" in the first SVA segment; DO NOT
include any S4A segments
The "body" can also be defined as a functional group, beginning with the first
byte of the segment immediately following the GS segment terminator and
including all transaction sets up to but not including the "S" in the first SVA
segment at the functional group level; DO NOT include any S3A segments
"This Assurance" is defined as from the "S" in S3A or S4A up to and including
the segment terminator of that segment
"Previous Assurance(s)" is defined as including the entire S3A or S4A segment
and the entire corresponding SVA segment that is associated with the S3A or S4A
at the same level
Codes (7)
Unique designation (identity) of the cryptographic process that performs the
stated assurance on data to be interchanged
Note: X9 has a required minimum length of 4 characters for a security
originator; no mechanism, or registration method, is provided by X9 or X12 to
guarantee uniqueness of the identifier
X9 has required minimum length of four characters for S4A05 (assurance
originator). No mechanism, or registration method, is provided by X9 or X12 to
guarantee uniqueness of the identifier.
Unique designation (identity) of the cryptographic process that performs
validation of the stated assurance on received data. In the absence of an
Assurance Recipient all potential receivers will often be able to validate the
assurance because the cryptographic technique is based on a "public" (as
opposed to "secret") technology
Note: X9 has required minimum length of 4 characters for a security recipient;
no mechanism, or registration method, is provided by X9 or X12 to guarantee
uniqueness of the identifier
X9 has a required minimum length of four characters for S4A06 (assurance
recipient). No mechanism, or registration method, is provided by X9 or X12 to
guarantee uniqueness of identifier.
Alphanumeric reference number issued by security assurance originator for the
particular assurance in which it occurs; unique when used in combination with
security originator data element
Date and time stamp in format as follows:
YYYYMMDDHHNNSSTTTZZZ+XXXX, where YYYY = 4 digit year (with leading century), MM
= month of year (01..12), DD = day of month (01..31), HH = hour of day in
24-hour format (00..23), NN = minutes of the hour (00-59), SS = second of hour
(00..59), TTT = [optional] milli-seconds (000..999), ZZZ = [optional] three
character, nominal timezone indicator (including daylight savings time
indicator) and XXXXX = 3-5 digit (including leading + or - sign) offset of time
to universal time, with three position format indicating hours-offset for whole
hours, and five position format indicating hours and minutes offset where this
is necessary. For example:
1993061522133OCDT+0930 which represents 15 June 1993, 22:13 (10:13pm), Central
Daylight Time (Nominal Value "CDT"), in a timezone that is offset + 9:30 from
Universal Time (Australia)
The date/time stamp may determine which of several key values apply, depending
on start and expiration dates of different key values that may share the same
keyname.
Any text needed to convey the name of a signatory, registration number,
certification number, or other assurance-originator defined or mutually-agreed
business text related to the specific assurance; this text is not defined for
X12 purposes and thus functions technically as "free-form text" though it may
have structure that is defined by the assurance originator, an industry group,
a governmental agency, or bi-laterally between assurance originator and
assurance recipient
