The information pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found in ETSI SR 000 314: “Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPR
19、s notified to ETSI in respect of ETSI standards“, which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web server (http:/webapp.etsi.org/IPR/home.asp). Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guaran

Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Electronic Sig
21、natures and Infrastructures (ESI). The present document is part 5 of a multi-part deliverable. Full details of the entire series can be found in part 1 i.6. Introduction Electronic documents are a major part of a modern companies business. Trust in this way of doing business is essential for the suc
22、cess and continued development of electronic business. It is, therefore, important that companies using electronic documents have suitable security controls and mechanisms in place to protect their documents and to ensure trust and confidence with their business practices. In this respect the electr
23、onic signature is an important security component that can be used to protect information and provide trust in electronic business. The present document is intended to cover electronic signatures for electronic documents. This includes evidence as to its validity even if the signer or verifying part
24、y later attempts to deny (i.e. repudiates; see ISO/IEC 10181-4 i.1) the validity of the signature. Thus, the present document can be used for any document encoded in a portable document format (PDF) produced by an individual and a company, and exchanged between companies, between an individual and a
25、 governmental body, etc. The present document is independent of any environment; it can be applied to any environment, e.g. smart cards, GSM SIM cards, special programs for electronic signatures, etc. The European Directive on a community framework for Electronic Signatures defines an electronic sig
26、nature as: “Data in electronic form which is attached to or logically associated with other electronic data and which serves as a method of authentication“. The formats defined in the present document, are able to support advanced electronic signatures as defined in the Directive. ISO 32000-1 4 spec
27、ifies a digital form for representing documents called the Portable Document Format (PDF) that enables users to exchange and view electronic documents easily and reliably, independent of the environment in which they were created or the environment in which they are viewed or printed. ISO 32000-1 4
28、identifies the ways in which an electronic signature, in the form of a digital signature, may be incorporated into a PDF document to authenticate the identity of the user and validate integrity of the documents content. These signatures are based on the same CMS 6 technology and techniques as TS 101
29、 733 5 (CAdES), but without the extended signature capabilities of CAdES. This profile specifies digital signatures on XML content that may be carried in a PDF document using XAdES based signatures. ETSI ETSI TS 102 778-5 V1.1.2 (2009-12)61 Scope The present document defines four profiles that toget
30、her profile the usage of XAdES 1 signatures, as defined in TS 101 903 1, for signing XML content within the PDF containers. The scope of the present document is limited to the following cases: 1) One XML document (compliant with an arbitrary XML language, like UBL for e-Invoicing) that is completely
31、 or partially signed with at least one enveloped XAdES signature and that is incorporated within a PDF container as a so-called “embedded“ document. In this situation, both the XML document and the XAdES signature(s) are created independently of the PDF container and after their creation, embedded w
32、ithin this container. NOTE 1: Implementers should be aware that any subsequent approval signature (see ISO 32000-1 4 clause 12.8.1) as specified in TS 102 778-2 i.7, TS 102 778-3 i.8 or TS 102 778-4 i.9 also signs the embedded signed XML document. Any upgrade of the XAdES signature of the present do
33、cument to support validation long after the expiration of the signing certificate or other extended features such a countersignatures (e.g. using XAdES-C or XAdES-X or XAdES-A) would invalidate the aforementioned approval signatures. Implementers should also be aware that certification signatures (s
34、ee ISO 32000-1 4 clause 12.8.1) as specified in TS 102 778-2 i.7, TS 102 778-3 i.8 or TS 102 778-4 i.9 signing the embedded signed XML document, may be used in conjunction with the DocMDP dictionary, allowing changes in the embedded signed XML document (by upgrading the XAdES signatures, for example
35、) without invalidating such signatures. 2) Signed (with XML Sig or XAdES signature) dynamic XFA 2 forms. The present document specifies profiles that apply to two different scenarios, namely: signing only the XML data of the XFA form, or signing any part of the XFA form that may be signed with a XML
36、 Sig signature. NOTE 2: XFA forms build up an XML-based architecture for managing forms within the PDF framework. In this architecture data, structure and rendering details appear as XML contents. According to the XFA specification not all this XML content may be signed with XML Sig. Being XAdES sig
37、natures built on XML Sig, XAdES signatures may sign only those XML contents that XFA specification allows to be signed with XML Sig. NOTE 3: Readers should be aware that although PDF documents are addressed for human beings, XFA forms, being them based on XML, may be consumed by software application
38、s. In addition to that, conforming signature handlers may be able to identify what parts of a certain form are signed by an XAdES signature. For each case two profiles are specified, namely: 1) One profile intended to be used by a signer, where basic forms of XAdES signatures (namely XAdES-BES, XAdE
39、S-EPES and XAdES-T) on the corresponding XML content are profiled. 2) One profile applicable to any party relying on a signature over a long period (e.g. longer than the lifetime of the signing certificate, also called long-term signature in the present document). It may be applied by a party receiv
40、ing and verifying the document or the signing party who should also verify the document when applying long term verification. It specifies how to include validation information and to further protect the signature using time-stamps so that it is possible to subsequently verify a XAdES signature long
41、 after it was generated. For the first case the present document specifies requirements for embedding a signed (with XAdES signatures) XML document within a PDF container as an embedded file. For the second case the present document specifies requirements for generating XAdES signatures on only the
42、XML data of the form, or on any XML content of the XFA form that may be signed with a XML Sig signature. For both cases the present document specifies requirements on the XAdES properties both signed and unsigned. Also for both cases the present document specifies requirements for upgrading of XAdES
43、 signatures from basic to more advanced forms.
