Long term signature specifications referenced

33、 element whose required level is “Conditional” in the CAdES-T profile, as specified in this part of ISO 14533, shall be provided.5.2 The generation or validation of CAdES-A data conforms to this part of ISO 14533 provided that the following requirements are met:a) all processing of elements whose re
34、quired level is “Mandatory” in the CAdES-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
35、.5.3 If first-party conformity assessment 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
36、 elements “Conditional”).NOTE Figure 1 shows the positioning of the generation and validation of CAdES-T data and CAdES-A data.6 Long term signature profiles6.1 Defined profilesIn order to make electronic signatures verifiable for a long term, signing time shall be identifiable, any illegal alterati
37、ons of information pertaining to 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 pertaini
38、ng to the generation and validation of CAdES-T data;b) CAdES-A profile: a profile pertaining to the generation and validation of CAdES-A data.Figure 1 shows the relation between CAdES-T data and CAdES-A data.9DIN ISO 14533-1:2015-05Figure 1 Relation between CAdES-T data and CAdES-A data6.2 Represent
39、ation of the required levelThis 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 an
40、 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”
41、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 who
42、se required level is Prohibited shall not be created or modified, may be read.6.3 Standard for setting the required levelThe 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 “Mandatory”
43、 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) The requi
44、red 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 elements with an ope
45、ration-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.”10DIN ISO 14533-1:2015-05e) The required level shall be “optional” for elements only containing reference information.6.4 Action
46、to take when an optional element is not implementedThe following action shall be taken when the CAdES data used in a validation transaction contains an unimplemented element.a) When the required level of an upper-level element is mandatory and one or more subordinate optional elements shall be selec
47、ted, or one or more relevant optional elements shall be selected, the validator shall be cautioned that validation requires implementation of said element(s); otherwise, validation cannot be performed.EXAMPLE In a validation transaction, a BasicOCSPResponse element is detected where only the process
48、ing of CertificateList elements, among all other optional elements in RevocationValues, is implemented.b) When CounterSignature is an unimplemented element, the validator shall be cautioned that validation requires implementation of said element; otherwise, validation cannot be performed.c) Optional
49、 elements other than those specified above may be ignored for implementation.6.5 CAdES-T profile6.5.1 GeneralThe required levels of constituent elements of CAdES-T data are specified in 6.5.2 to 6.5.4.If a certification authority (CA) or other trusted service is trusted to maintain and keep certificates for the signature validation accessible for an appropriate period of time and parties relying on the signature validity know the location where the certificates are a
