7、33-1:2014(E) Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject

8、for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) o

9、n all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees

10、are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held

11、 responsible for identifying any or all such patent rights. ISO 14533-1 was prepared by Technical Committee ISO/TC 154, Processes, data elements and documents in commerce, industry and administration. This second edition cancels and replaces the first edition (ISO 14533-1:2012), which has been techn

12、ically revised. The main changes compared with the previous edition are that Clause 6 and Annexes A and B have been technically revised with the addition of a new archive time-stamp format: archive-time- stamp-v3 (ATSv3) and an associated attribute ats-hash-index. ISO 14533 consists of the following

37、ES-A profile, as specified in this part of ISO 14533, shall be included; b) detailed specifications pertaining to the processing of any element whose required level is “Conditional” in the CAdES-A profile, as specified in this part of ISO 14533, shall be provided. 5.3 If first-party conformity asses

38、sment is used, the implementer shall make a declaration of conformity to this part of ISO 14533 by disclosing the suppliers declaration of compliance and its attachment (see Annex A) containing a description of implementation status (and the specifications for any elements “Conditional”). NOTE Figur

40、 signatures, including the subject of information and validation data, shall be detectable, and interoperability ensured. To meet these requirements, this part of ISO 14533 defines the following two profiles with respect to CAdES: a) CAdES-T profile: a profile pertaining to the generation and valida

41、tion of CAdES-T data; b) CAdES-A profile: a profile pertaining to the generation and validation of CAdES-A data.

42、tion of the required level This part of ISO 14533 defines the following representation methods for the required level (as a profile) of each element constituting CAdES-T data and CAdES-A data. a) Mandatory (M): Elements whose required level is “Mandatory” shall be implemented without fail. If such a

43、n element has optional subelements, at least one subelement shall be selected. Any element whose required level is “Mandatory” and is one of the subelements of an optional element shall be selected whenever the optional element is selected. b) Optional (O): Elements whose required level is “Optional

44、” may be implemented at the discretion of the implementer. c) Conditional (C): Elements whose required level is “Conditional” may be implemented at the discretion of the implementer, provided that detailed specifications for the processing thereof are provided separately. d) Prohibited (P): Elements

45、 whose required level is Prohibited shall not be created or modified, may be read. 6.3 Standard for setting the required level The required level of each element constituting CAdES- T data and CAdES-A data shall be set in accordance with the following requirements. a) The required level shall be “Ma

46、ndatory” for elements whose required level is “Mandatory” in the definition of CAdES, and those necessary for the generation and validation of long term signatures. The elements whose required level is “Optional” in the definition of CAdES are defined as “Mandatory”, “Optional” or “Conditional”. b)

47、The required level shall be “Conditional” for externally defined elements. EXAMPLE 1 OtherCertificateFormat. c) The required level shall be “Conditional” for elements intended to interact with a certain application. EXAMPLE 2 ContentReference. d) The required level shall be “Conditional” for element

48、s with an operation-dependent factor. EXAMPLE 3 Attribute certificate; time mark. NOTE The archiving-type timestamp defined in ISO/IEC 18014-2 is included in “Time mark or other method.” ISO 2014 All rights reserved 5 ISO 14533-1:2014(E) e) The required level shall be “optional” for elements only co
