Foreword This Technical Specification (TS) has been produced by ETSI Technica

19、l Committee Electronic Signatures and Infrastructures (ESI). Introduction TS 101 733 1 (CAdES henceforth) specifies formats for Advanced Electronic Signatures built on CMS 2. That document defines a number of signed and unsigned optional signature attributes, resulting in support for a number of var

20、iations in the signature contents and powerful processing requirements. In order to maximize interoperability in communities applying CAdES 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 p

21、rofile. The present document defines three profiles that minimize the differences between implementations and so maximize interoperability. The two first profiles are suitable for specific business areas, namely e-Invoicing and e-Government, respectively. The third profile provides a baseline for ot

22、her application areas. Profiles specified in clauses 5, 6 and 7 are based on the actual usage of the CMS 2 and CAdES 1 options, 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 rep

23、resent a general consensus of the use of these standards and hence provide a reliable basis for maximizing interoperability. 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 102 734 V1.1.1

24、 (2007-02) 6 1 Scope The present document profiles the use of TS 101 733 (CAdES) 1 signatures, based on CMS 2 for its use 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 requirem

25、ents of the referenced standards, but their aim is to maximize interoperability of CMS-based advanced electronic signatures 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. Option

26、al elements defined in CAdES 1 but not specified in the current document are treated as optional for both generator and verifiers. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

34、ains 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, clause 5.1 10. protocol element: eleme

35、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

36、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, clause 5.1 10. verifier: entity that validates or verifies an electronic signature The present document makes use of certain key words to signify requi

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. shou

38、ld: 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,

39、 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 CAdES CMS Advanced Electronic Signatures NOTE: As per TS 101 733 1.

41、 requirements 4.1 Algorithm requirements Implementers are strongly recommended to take into account TS 102 176-1 9 when selecting algorithms and key lengths. 4.2 Compliance requirements Profiles in the present document define separated requirements for both generator and verifier of CAdES signatures

42、. Requirements are grouped in three different categories, each one having its corresponding identifier. Table 1 defines these categories and their identifiers. Table 1: Requirement categories Identifier Requirement on generator Requirement on verifier M Generator shall include the element in the sig

43、nature. 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 process or ignore this element and process the rest of the signature. Clauses

44、5 to 7 specify additional requirements on signature formats that must be taken into account along with those ones already present in TS 101 733 (CAdES) 1 and CMS 2. Systems claiming to support the CAdES profile for e-Invoicing shall be compliant with requirements in clauses 5.1, 5.2, 5.3 and 5.5. Sy

45、stems claiming to support the CAdES 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 CAdES profile for e-Government shall be compliant with requirements in clauses 6.1, 6.2, 6.3 and 6.5. Systems cla

46、iming to support the CAdES 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 CAdES baseline profile shall be compliant with requirements in clauses 7.1, 7.2, 7.3 and 7.5. Systems claiming to support

47、 the CAdES baseline profile with support of long term signatures shall also be compliant with requirements in clause 7.4. Optional elements defined in CAdES 1 but not specified in the current document are treated as “O“ as above for both generator and verifiers. In certain cases, elements are marked

48、 with an “O“ for both generator and verifier to bring the readers“ attention to the fact that their processing is optional. Certain service elements may be provided by different protocol elements at users choice. In these cases the semantics of M, R and O defined in the table above depend on the req

49、uirement 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 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 choic
