18、Rights IPRs essential or potentially essential to the present document may have been declared to ETSI. 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); Essent
19、ial, or potentially Essential, IPRs 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:/ipr.etsi.org). Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out
20、by ETSI. No guarantee can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web server) which are, or may be, or may become, essential to the present document. Foreword This Technical Specification (TS) has been produced by ETSI Technical Commit
21、tee Electronic Signatures and Infrastructures (ESI). The present document was previously published as ETSI TS 102 023 i.8. 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
22、described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of provisions). “must“ and “must not“ are NOT allowed in ETSI deliverables except when used in direct citation. Introduction The present document is aiming to meet the general requirements of the international commun
23、ity to provide trust and confidence in electronic transactions including, amongst others, applicable requirements from Regulation (EU) No 910/2014 i.4. The Regulation includes requirements for Trust Service Providers (TSP) providing services to the public, including TSPs issuing time-stamps. Additio
24、nally, more specific requirements are identified in the Regulation for a specific class of TSP called a Qualified TSP, with further specific requirements for those Qualified TSPs which issue qualified time-stamps. The present document is aimed to meet the requirements of the Regulation for both Qual
25、ified and non-Qualified TSPs issuing Qualified and non-Qualified electronic time-stamps respectively. In order to verify an electronic signature, it can be necessary to prove that the signature from the signer was applied when the signers certificate was valid. This is necessary in two circumstances
26、: 1) during the validity period of the signers certificate, should the signers certificate be revoked before the end of its validity, e.g. because the signers private key has been compromised; 2) after the end of the validity period of the signers certificate, since CAs are not mandated to process r
27、evocation status information beyond the end of the validity period of the certificates they have issued. One method consists to use a time-stamp which allows proving that a datum existed before a particular time. This technique allows proving that the signature was generated before the date containe
28、d in the time-stamp. Policy requirements to cover that case are the primary aim of the present document. However, these policy requirements allow addressing other needs. Time-stamping is gaining an increasing interest by the business sector and is becoming an important component of digital signature
29、s, this is commonly based upon the Time-Stamp protocol from the IETF RFC 3161 i.2 which is profiled in ETSI TS 119 422 5. Agreed minimum security and quality requirements are necessary in order to ensure trustworthy validation of long-term digital signatures. ETSI ETSI TS 119 421 V1.0.1 (2015-07)61
30、Scope The present document specifies policy and security requirements relating to the operation and management practices of TSPs issuing time-stamps. These policy requirements are applicable to TSPs issuing time-stamps. Such time-stamps can be used in support of digital signatures or for any applica
31、tion requiring to prove that a datum existed before a particular time. The present document can be used by independent bodies as the basis for confirming that a TSP can be trusted for issuing time-stamps. The present document does not specify: protocols used to access the TSUs; NOTE 1: A time-stampi
32、ng protocol is defined in IETF RFC 3161 i.2 including optional update in IETF RFC 5816 i.3 and profiled in ETSI TS 119 422 5. how the requirements identified herein can be assessed by an independent body; requirements for information to be made available to such independent bodies; requirements on s
33、uch independent bodies.
