(Main)Electronic Signatures and Infrastructures (ESI) - Policy and Security Requirements for Trust Service Providers issuing Time-Stamps
Electronic Signatures and Infrastructures (ESI) - Policy and Security Requirements for Trust Service Providers issuing Time-Stamps
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 application 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-stamping protocol is defined in IETF RFC 3161 [i.2] including optional update in IETF
RFC 5816 [i.3] and profiled in ETSI EN 319 422 [5].
The present document does not specify how the requirements identified can be assessed by an independent party,
including requirements for information to be made available to such independent assessors, or requirements on such
assessors.
NOTE 2: See ETSI EN 319 403-1 [i.9] for guidance on assessment of TSP's processes and services.
NOTE 3: The present document references ETSI EN 319 401 [4] for general policy requirements common to all
classes of TSP's services.
Elektronski podpisi in infrastruktura (ESI) - Zahteve politike in varnosti za ponudnike storitev zaupanja, ki izdajajo časovne žige
Ta dokument določa zahteve politike in varnosti za delovanje in upravljanje ponudnikov storitev zaupanja, ki izdajajo časovne žige.
Te zahteve politike se uporabljajo za ponudnike storitev zaupanja, ki izdajajo časovne žige. Tovrstni časovni žigi se lahko uporabljajo kot podpora za digitalne podpise ali za kateri koli način uporabe, pri katerem se zahteva dokazilo, da je datum že obstajal pred določenim časom.
Neodvisni organi lahko ta dokument uporabijo kot podlago za potrjevanje, da lahko ponudnik storitev zaupanja zanesljivo izdaja časovne žige.
Ta dokument ne določa protokolov za dostop do uporabnikov storitev zaupanja (TSU).
OPOMBA 1: Protokol za časovno žigosanje je določen v standardu IETF RFC 3161 [i.2], vključno z izbirno posodobitvijo v standardu IETF
RFC 5816 [i.3] in profilom v standardu ETSI EN 319 422 [5].
Ta dokument ne določa, kako lahko opredeljene zahteve oceni neodvisna stran, vključno z zahtevami glede informacij, ki jih je treba razkriti takim neodvisnim ocenjevalcem, ali zahtevami glede takih ocenjevalcev.
OPOMBA 2: Glej standard ETSI EN 319 403-1 [i.9] za navodila v zvezi z ocenjevanjem procesov in storitev ponudnikov storitev zaupanja.
OPOMBA 3: Ta dokument se sklicuje na standard ETSI EN 319 401 [4] za splošne zahteve politike, ki so skupne vsem razredom storitev ponudnikov storitev zaupanja.
