Introduction Electronic commerce has emerged as a frequent way of doing busin
18、ess 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 suitable security controls
19、 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 present document is int
20、ended 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 Regulation (EU) No 910/2014 i.8.
21、 ETSI ETSI EN 319 122-2 V1.1.1 (2016-04) 5 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
22、 e.g. smart cards, 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. ETS
23、I ETSI EN 319 122-2 V1.1.1 (2016-04) 6 1 Scope The present document specifies CAdES digital signatures. CAdES signatures are built on CMS signatures i.9, by incorporation of signed and unsigned attributes, which fulfil certain common requirements (such as the long term validity of digital signatures
24、, for instance) in a 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
25、are below it. These CAdES extended signatures a higher degree of optionality than the CAdES baseline signatures specified in ETSI EN 319 122-1 1. Procedures for creation, augmentation, and validation of CAdES digital signatures are out of scope and specified in ETSI EN 319 102-1 i.5. Guidance on cre
26、ation, augmentation and validation of CAdES digital signatures including the usage of the different properties is provided in ETSI TR 119 100 i.4. The present document aims at supporting digital signatures in different regulatory frameworks. NOTE: Specifically but not exclusively, CAdES digital sign
27、atures specified in the 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.8. 2 References 2.1 Normative references

38、, the abbreviations given in ETSI TR 119 001 i.3 apply. 4 Additional CAdES levels without references to validation 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 EN 319 122-1 1. NOTE 1: ETS
39、I TR 119 100 i.4 provides a description on the life-cycle of a signature and the rationales on which level is suitable in which situation. NOTE 2: Clause 4.3 defines four CAdES levels namely the CAdES-E-BES, CAdES-E-EPES, CAdES-E-T, and CAdES-E-A built on CAdES-E-T. The normative annex A defines lev
40、els of CAdES signatures incorporating attributes that encapsulate references to validation data and attributes that encapsulate time-stamp tokens on the aforementioned references. NOTE 3: The requirements on the presence and cardinality of the attributes for each CAdES signature level are expressed
41、in tables whose formats and semantics are as specified in clause 6.2.2 of ETSI EN 319 122-1 1. 4.2 General requirements The general CMS syntax shall be as specified in ETSI EN 319 122-1 1, clause 4. The signature shall contain a CMS SignedData, as defined in ETSI EN 319 122-1 1, clause 4.4 and at le
42、ast one SignerInfo (ETSI EN 319 122-1 1, clauses 4.6). The algorithms and key lengths used to generate and augment digital signatures should be as specified in ETSI TS 119 312 i.7. ETSI ETSI EN 319 122-2 V1.1.1 (2016-04) 8 NOTE: Cryptographic suites recommendations defined in ETSI TS 119 312 i.7 can
43、 be superseded by national recommendations. 4.3 CAdES-E-BES, CAdES-E-EPES, CAdES-E-T and CAdES-E-A built on CAdES-E-T signatures CAdES-E-BES, CAdES-E-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 pres
44、ent clause. CAdES-E-EPES signatures are built on CAdES-E-BES signatures by adding one signature-policy-identifier 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, CA
45、dES-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. 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. ETSI ETSI EN 319 12
