The present document is part 1 of a multi-part deliverable covering the PDF digital signatures (PAdES), as ide

16、ntified below: Part 1: “Building blocks and PAdES baseline signatures“; Part 2: “Additional PAdES signatures profiles“. Modal verbs terminology In the present document “shall“, “shall not“, “should“, “should not“, “may“, “need not“, “will“, “will not“, “can“ and “cannot“ are to be interpreted as des

Introduction Electronic commerce has emerged as a frequent way of doing business between companies across l

18、ocal, wide area and global networks. Trust in this way of doing business is essential for the success and continued development of electronic commerce. It is therefore important that companies using this electronic means of doing business have suitable security controls and mechanisms in place to pr

19、otect their transactions and to ensure trust and confidence with their business partners. In this respect digital signatures are an important security component that can be used to protect information and provide trust in electronic business. The present document is intended to cover digital signatu

20、res supported by PKI and public key certificates, and aims to meet the general requirements of the international community to provide trust and confidence in electronic transactions, including, amongst other, applicable requirements from Regulation (EU) No 910/2014 i.2. The present document can be u

21、sed for any transaction between an individual and a company, between two companies, between an individual and a governmental body, etc. The present document is independent of any environment. It can be applied to any environment e.g. smart cards, SIM cards, special programs for electronic signatures

22、, etc. The present document is part of a rationalized framework of standards (see ETSI TR 119 000 i.3). ETSI TR 119 100 i.4 provides guidance on how to use the present document within the aforementioned framework. ETSI ETSI TS 119 142-1 V1.0.1 (2015-07)51 Scope The present document, specifies PAdES

23、digital signatures. PAdES signatures build on PDF signatures specified in ISO 32000-1 1 with an alternative signature encoding to support digital signature formats equivalent to the signature format CAdES as specified in ETSI TS 119 122-1 2, by incorporation of signed and unsigned attributes, which

24、fulfil certain common requirements (such as the long term validity of digital signatures) in a number of use cases. The present document specifies formats for PAdES baseline signatures, which provide the basic features necessary for a wide range of business and governmental use cases for electronic

25、procedures and communications to be applicable to a wide range of communities when there is a clear need for interoperability of digital signatures used in electronic documents. The present document defines four levels of PAdES baseline signatures addressing incremental requirements to maintain the

26、validity of the signatures over the long term, in a way that a certain level always addresses all the requirements addressed at levels that are below it. Each level requires the presence of certain PAdES attributes, suitably profiled for reducing the optionality as much as possible. Procedures for c

27、reation and validation of PAdES digital signatures are out of scope and specified in ETSI TS 119 102 i.5. The present document aim at supporting electronic signatures in different regulatory frameworks. NOTE: Specifically but not exclusively, PAdES digital signatures specified in the present documen

28、t aim at supporting electronic signatures, advanced electronic signatures, qualified electronic signatures, electronic seals, advanced electronic seals, and qualified electronic seals as per Regulation (EU) No 910/2014 i.2. 2 References 2.1 Normative references References are either specific (identi
