Introduction The present document is aiming to meet the general requirements of the international community to provide trust and confidence in electronic transactions including, amongst others, applicable requirements from Regulati
25、on (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. Additionally, more specific requirements are identified in the Regulation for a specific class of TSP called a Qualified TSP, with fur
26、ther 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 Qualified and non-Qualified TSPs issuing Qualified and non-Qualified electronic time-stamps respectively. In order to verify an ele
27、ctronic 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: 1) during the validity period of the signers certificate, should the signers certificate be revoked before the end of its val
28、idity, 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 revocation status information beyond the end of the validity period of the certificates they have issued. ETSI ETSI EN 319 421 V
29、1.1.1 (2016-03) 6 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 contained in the time-stamp. Policy requirements to cover that case are the primary aim of the
30、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 signatures, this is commonly based upon the Time-Stamp protocol from the IETF RFC 3161 i.2 which
31、 is profiled in ETSI EN 319 422 5. Agreed minimum security and quality requirements are necessary in order to ensure trustworthy validation of long-term digital signatures. ETSI ETSI EN 319 421 V1.1.1 (2016-03) 7 1 Scope The present document specifies policy and security requirements relating to the
32、 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 application requiring to prove that a datum existed before a particular time. The present do
33、cument 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-stamping protocol is defined in IETF RFC 3161 i.2 including optional update in IETF RFC 581
34、6 i.3 and profiled in ETSI EN 319 422 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 such independent bodies.
