Processes, data elements and documents in commerce, industry and administration. Long term signature profiles-Attributes pointing to (external) proof of existence objects used in long term signature formats (PoEAttributes)
商业、工业和行政管理中的流程、数据元素和文档 长期特征文件
This document specifies the elements defined in the international standards of ISO/ITU-T, ETSI
and IETF RFC that enable at least a proof of existence of data objects and digital signatures and the
preservation of the validity status of digital signatures over a long period of time used in validation.
It provides the definitions of the proof of existence (PoE) attributes and clarification of the usage of
(external) PoE objects, with digital signatures and trusted time values, which have already existed
and can be used by the PoE attributes pointing to (external) PoE objects used in long term signature
validation or preservation.Cross References:IETF RFC 4998IETF RFC 3161ISO/IEC 8825-1IETF RFC 6283V1.1.1:2016-04ISO/IEC 9594-8IETF RFC 5652ETSI EN 319 122-1IETF RFC 4648ISO 32000-2IETF RFC 6960IETF RFC 8089IETF RFC 2231ISO/IEC 8825-8IETF RFC 3986IETF RFC 2045IETF RFC 7231ISO 14533-1ETSI TS 119 512ETSI TS 119 511EN 319 122-3IETF RFC 6532ISO 14533-2ISO 14533-3IETF RFC 7230ETSI EN 319 162-1ETSI EN 319 132-1IETF RFC 2183ETSI SR 019 510IETF RFC 2634ISO/IEC 7816-4:2013All current amendments available at time of purchase are included with the purchase of this document.
