Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Electronic Signatures and Infrastructures (ESI). Introduction TS 101 903 1 (XAdES henceforth) specifies formats for Advan

19、ced Electronic Signatures built on XML SIG 2. That document defines a number of signed and unsigned optional signature attributes, resulting in support for a number of variations in the signature contents and powerful processing requirements. In order to maximise interoperability in communities appl

20、ying XAdES to particular environments it is necessary to identify a common set of options that are appropriate to that environment. Such a selection is commonly called a profile. The present document defines three profiles that minimise the differences between implementations and so maximise interop

21、erability. The two first profiles are suitable for specific business areas, namely e-Invoicing and e-Government, respectively. The third profile provides a baseline for other application areas. Profiles specified in clauses 5, 6 and 7 are based on the actual usage of the XML SIG 2 and XAdES 1 option

22、s, as emerged from a survey conducted by ETSI over a substantial number of prominent European actors in the electronic signature domain. Therefore the following provisions represent a general consensus of the use of these standards and hence provide a reliable basis for maximising interoperability.

23、Nevertheless, in particular business areas and niches there may be specific needs and/or regulations that may require variations to these profiles. ETSI ETSI TS 102 904 V1.1.1 (2007-02) 6 1 Scope The present document profiles the use of TS 101 903 (XAdES) 1 signatures, based on XML SIG 2 for its use

24、 within the following specific environments as follows: e-Invoicing area. e-government area. a baseline for other application areas. These profiles do not repeat the base requirements of the referenced standards, but their aim is to maximise interoperability of XML-based advanced electronic signatur

25、es in the e-Invoicing and e-Government business areas. In addition to that, the baseline profile is given as basis for interoperability profiles in other application areas. Optional elements defined in XAdES 1 but not specified in the current document are treated as optional for both generator and v

26、erifiers. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

33、tains the signature. long term signatures: signatures that are expected to be verified beyond the signers certificate expiration date and, possibly, even after the expiration date of the certificate of the signers certificate-issuing CA NOTE: Refer to CWA 14171 8, clause 5.1. protocol element: eleme

34、nt of the protocol which may be including data elements and / or elements of procedure service element: element of service that may be provided using one or more protocol elements NOTE: All alternative protocol elements provide an equivalent service to the users of the protocol. short term signature

35、s: signatures that are to be verified for a period of time that does not go beyond the signers certificate expiration date NOTE: Refer to CWA 14171 8, clause 5.1. verifier: entity that validates or verifies an electronic signature The present document makes use of certain key words to signify requir

36、ements. Below follows their definitions: may: Means that a course of action is permissible within the limits of the present document. shall: Means that the definition is an absolute requirement of the present document. It has to strictly be followed in order to conform to the present document. shoul

37、d: Means that among several possibilities one is recommended as particularly suitable, without mentioning or excluding others, or that a certain course of action is preferred but not necessarily required. Implementers may know valid reasons in particular circumstances to ignore this recommendation,

38、but the full implications must be understood and carefully weighed before choosing a different course. 3.2 Abbreviations For the purposes of the present document, the following abbreviations apply: CA Certification Authority CEN European Committee for standardization CRL Certificate Revocation List

41、eparated requirements for both generator and verifier of XAdES signatures. Requirements are grouped in four different categories, each one having its corresponding identifier. Table 1 defines these categories and their identifiers. Table 1: Requirement categories Identifier Requirement on generator

42、Requirement on verifier M Generator shall include the element in the signature. Verifier shall process the element. R Generator should include the element in the signature. Verifier shall process the element if present. O Generator may include the element in the signature. Verifier may either proces

43、s or ignore this element and process the rest of the signature. Clauses 5 to 7 specify additional requirements on signature formats that must be taken into account along with those ones already present in TS 101 903 (XAdES) 1 and XML SIG 2. Systems claiming to support the XAdES profile for e-Invoici

44、ng shall be compliant with requirements in clauses 5.1, 5.2, 5.3 and 5.5. Systems claiming to support the XAdES profile for e-Invoicing with support for long term signatures shall also be compliant with requirements in clause 5.4. Systems claiming to support the XAdES profile for e-Government shall

45、be compliant with requirements in clauses 6.1, 6.2, 6.3 and 6.5. Systems claiming to support the XAdES profile for e-Government with support for long term signatures shall also be compliant with requirements in clause 6.4. Systems claiming to support the baseline XAdES profile shall be compliant wit

46、h requirements in clauses 7.1, 7.2, 7.3 and 7.5. Systems claiming to support the baseline XAdES profile with support for long term signatures shall also be compliant with requirements in clause 7.4. Optional elements defined in XAdES 1 but not specified in the current document are treated as “O“ as

47、above for both generator and verifiers. In certain cases, elements are included marked with an “O“ for both generator and verifier to bring the readers“ attention to the fact that it is optional. Certain service elements may be provided by different protocol elements at users choice. In these cases

48、the semantics of M, R and O defined in the table above depend on the requirement for the service element itself. Tables 2 to 4 (each one applies to a different requirement on the service element) define these semantics. Table 2: Requirements for mandatory service with choices Requirement Identifier

49、for the Service / Protocol element Requirement on generator Requirement on verifier Service = M Generator shall provide the service by including one protocol element chosen from the list of choices. Verifiers shall be able to process at least one of the protocol elements in the list of choices. Protocol Choice = R Generator should use this protocol element for providing the mandatory service element. Verifiers shall process this protocol element if present. Protocol Choice = O Generator may use this protocol element
