This Recommendation | International Standard will define those TTP services needed to support the application of digital<\/p>\n
signatures for the purpose of non-repudiation of creation of documents.<\/p>\n
This Recommendation | International Standard will also define interfaces and protocols to enable interoperability<\/p>\n
between entities associated with these TTP services.<\/p>\n
Definitions of technical services and protocols are required to allow for the implementation of TTP services and related<\/p>\n
commercial applications.<\/p>\n
This Recommendation | International Standard focuses on:<\/p>\n
? implementation and interoperability;<\/p>\n
? service specifications; and<\/p>\n
? technical requirements.<\/p>\n
This Recommendation | International Standard does not describe the management of TTPs or other organizational,<\/p>\n
operational or personal issues. Those topics are mainly covered in ITU-T Rec. X.842 | ISO\/IEC TR 14516, Information<\/i><\/p>\n
technology ? Security techniques ? Guidelines on the use and management of Trusted Third Party services<\/i>.<\/p>\n
NOTE 1 ? Because interoperability is the main issue of this Recommendation | International Standard, the following restrictions<\/p>\n
hold:<\/p>\n
i) Only those services which may be offered by a TTP, either to end entities or to another TTP, are covered in this<\/p>\n
Recommendation | International Standard.<\/p>\n
ii) Only those services which may be requested and\/or delivered by means of standardizable digital messages are<\/p>\n
covered.<\/p>\n
iii) Only those services for which widely acceptable standardized messages can be agreed upon at the time this<\/p>\n
Recommendation | International Standard is published are specified in detail.<\/p>\n
Further services will be specified in separate documents when widely acceptable standardized messages are available for them. In<\/p>\n
particular, time stamping services will be defined in a separate document.<\/p>\n
NOTE 2 ? The data structures and messages in this Recommendation | International Standard will be specified in accordance to<\/p>\n
RFC documents, RFC 2510 and RFC 2511 (for certificate management services) and to RFC 2560 (for OCSP services). The<\/p>\n
certificate request format also allows interoperability with PKCS#10. See Annex C for references to the documents mentioned in<\/p>\n
this Note.<\/p>\n
NOTE 3 ? Other standardization efforts for TTP services in specific environments and applications, like SET or EDIFACT, exist.<\/p>\n
These are outside of the scope of this Recommendation | International Standard.<\/p>\n
NOTE 4 ? This Recommendation | International Standard defines technical specifications for services. These specifications are<\/p>\n
independent of policies, specific legal regulations, and organizational models (which, for example, might define how duties and<\/p>\n
responsibilities are shared between Certification Authorities and Registration Authorities). Of course, the policy of TTPs offering<\/p>\n
the services described in this Recommendation | International Standard will need to specify how legal regulations and the other<\/p>\n
aspects mentioned before will be fulfilled by the TTP. In particular, the policy has to specify how the validity of digital signatures<\/p>\n
and certificates is determined.<\/p>\n","protected":false},"excerpt":{"rendered":"
