Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Electronic Signatures and Infrastructures (ESI). The present document is part 2 of a multi-part deliverable covering CAdES digital signatures. Fu

15、ll details of the entire series can be found in part 1 1. The present document partly contains an evolved specification of CAdES previously published as ETSI TS 101 733 i.1. Modal verbs terminology In the present document “shall“, “shall not“, “should“, “should not“, “may“, “need not“, “will“, “will

Introduction Electronic commerce has emerged as a fre

17、quent way of doing business between companies across local, 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 su

18、itable security controls and mechanisms in place to protect 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

19、 present document is intended to cover digital signatures 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 Regulati

20、on (EU) No 910/2014 i.7. The present document can be used 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,

21、 GSM SIM cards, special programs for electronic signatures, etc. The present document is part of a rationalized framework of standards (see ETSI TR 119 000 i.2). See ETSI TR 119 100 i.4 for getting guidance on how to use the present document within the aforementioned framework. ETSI ETSI TS 119 122-

22、2 V1.0.1 (2015-07)51 Scope The present document specifies CAdES digital signatures. CAdES signatures are built on CMS signatures i.8, by incorporation of signed and unsigned attributes, which fulfil certain common requirements (such as the long term validity of digital signatures, for instance) in a

23、 number of use cases. The present document specifies a number of CAdES signature levels addressing incremental requirements to maintain the 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. These

24、CAdES extended signatures a higher degree of optionality than the CAdES baseline signatures specified in ETSI TS 119 122-1 1. The present document aims at supporting digital signatures in different regulatory frameworks. NOTE: Specifically but not exclusively, CAdES digital signatures specified in t

25、he present document 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.7. 2 References 2.1 Normative references References are eithe

35、signature: digital signature that satisfies the requirements specified within the present document digital signature: data appended to, or a cryptographic transformation (see cryptography) of a data unit that allows a recipient of the data unit to prove the source and integrity of the data unit and

36、protect against forgery e.g. by the recipient legacy CAdES 101 733 signature: CAdES signature generated according to ETSI TS 101 733 i.1 3.2 Abbreviations For the purposes of the present document, the abbreviations given in ETSI TR 119 001 i.3 apply. 4 Additional CAdES levels without references to v

37、alidation data 4.1 Overview The present document specifies a number of additional levels of CAdES. Each level is created by a combination of attributes defined in ETSI TS 119 122-1 1. NOTE 1: Clause 4.3 defines four CAdES levels namely the CAdES-E-BES, CAdES-E-EPES, CAdES-E-T, and CAdES-E-A built on

38、 CAdES-E-T. The normative annex A defines levels of CAdES signatures incorporating attributes that encapsulate references to validation data and attributes that encapsulate time-stamp tokens on the aforementioned references. NOTE 2: The requirements on the presence and cardinality of the attributes

39、for each CAdES signature level are expressed in tables whose formats and semantics are as specified in clause 6.2.2 of ETSI TS 119 122-1 1. 4.2 General requirements The general CMS syntax shall be as specified in ETSI TS 119 122-1 1, clause 4. The signature shall contain a CMS SignedData, as defined

40、 in ETSI TS 119 122-1 1, clause 4.4 and at least one SignerInfo (ETSI TS 119 122-1 1, clauses 4.6). The algorithms and key lengths used to generate signatures should comply with ETSI TS 119 312 i.6. ETSI ETSI TS 119 122-2 V1.0.1 (2015-07)74.3 CAdES-E-BES, CAdES-EPES, CAdES-E-T and CAdES-E-A built on

41、 CAdES-E-T signatures CAdES-E-BES, CAdES-EPES, CAdES-E-T, and CAdES-E-A built on CAdES-E-T signatures shall be CAdES signatures whose attributes satisfy the requirements specified in the present clause. CAdES-E-EPES signatures are built on CAdES-E-BES signatures by adding one signature-policy-identi

42、fier attribute. CAdES-E-T signatures are built on CAdES-E-BES or CAdES-E-EPES signatures by adding one or more signature-time-stamp attributes. CAdES-E-A signatures are built on CAdES-E-T, CAdES-E-C, CAdES-E-X (of Type 1 and of Type 2), CAdES-E-X-Long, and CAdES-E-X-L (of Type 1 and of Type 2) signa

43、tures. Annex A specifies CAdES-E-C, CAdES-E-X (of Type 1 and of Type 2), CAdES-E-X-Long, and CAdES-E-X-L (of Type 1 and of Type 2) signatures, and CAdES-E-A built on them.
