标准摘要
[中文适用范围]: 本文件规定了 ISO/ITU-T、ETSI 和 IETF RFC 国际标准中定义的元素,这些元素至少能够证明数据对象和数字签名的存在,并在很长一段时间内保存数字签名的有效性状态。 验证中使用的时间。 它提供了存在证明 (PoE) 属性的定义,并澄清了(外部)PoE 对象的使用,具有数字签名和可信时间值,这些对象已经存在,可以由指向(外部)的 PoE 属性使用用于长期签名验证或保存的 PoE 对象。 [外文原描述]: 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.
