Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Electronic Signatures and Infrastructures (ESI). The
17、 present document is part 1 of a multi-part deliverable covering PDF Advanced Electronic Signature Profiles, as identified below: Part 1: “PAdES Overview - a framework document for PAdES“; Part 2: “PAdES Basic - Profile based on ISO 32000-1“; Part 3: “PAdES Enhanced - PAdES-BES and PAdES-EPES Profil
18、es“; Part 4: “PAdES Long Term - PAdES-LTV Profile“; Part 5: “PAdES for XML Content - Profiles for XAdES signatures“. Introduction Electronic documents are a major part of a modern companies business. Trust in this way of doing business is essential for the success and continued development of electr
19、onic 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 electronic signature is an important security
20、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 party later attempts to deny (i.e. repudiate
21、s; 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 governmental body, etc. The present doc
22、ument 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 signature as: “Data in electronic form whic
23、h 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 1 specifies a digital form for representing doc
24、uments 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. ETSI ETSI TS 102 778-1 V1.1.1 (2009-07)5ISO 32000-1 1 i
25、dentifies 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 5 technology and techniques as TS 101
26、733 2 (CAdES), but without the extended signature capabilities of CAdES. ETSI ETSI TS 102 778-1 V1.1.1 (2009-07)61 Scope The present document provides a framework for the set of profiles for PDF (Portable Document Format - as specified in ISO 32000-1 1) Advanced Electronic Signatures specified in th
27、is multi-part deliverable. This multi-part deliverable profiles and extends the support for electronic signatures specified in ISO 32000-1 1 to include the enhanced features for advanced electronic signatures. These profiles include features equivalent to those specified in TS 101 733 2 (CAdES) and
28、TS 101 903 3 (XAdES) and include support for validation of signed documents stored over long periods. The present document: a) Provides a general description of support for signatures in PDF documents including use of XML signatures to protect XML data in PDF documents; b) Lists the features of the
29、PDF profiles specified in other parts of the document; c) Describes how the profiles may be used in combination. The present document is for information only. Reference should be made to the other parts of this deliverable for the normative requirements of each profile. 2 References References are e
30、ither specific (identified by date of publication and/or edition number or version number) or non-specific. For a specific reference, subsequent revisions do not apply. Non-specific reference may be made only to a complete document or a part thereof and only in the following cases: - if it is accept
