标准范围

ISO/IEC 18014-2:20 09提出了提供时间戳服务的一般框架。时间戳服务可以生成、更新和验证时间戳令牌。时间戳令牌是数据和时间点之间的关联，并且以旨在提供数据在相关日期和时间存在的证据的方式创建。此外，不可否认服务可以使用证据。ISO/IEC 18014-2:20 04规定了生成独立时间戳的机制:为了验证独立时间戳令牌，验证者不需要访问任何其他时间戳令牌。也就是说，时间戳令牌不被链接，就像ISO/IEC 18014-3中定义的令牌类型的情况一样。

ISO/IEC 18014-2:2009 presents a general framework for the provision of time-stamping services.

Time-stamping services may generate, renew and verify time-stamp tokens.

Time-stamp tokens are associations between data and points in time, and are created in a way that aims to provide evidence that the data existed at the associated date and time. In addition, the evidence may be used by non-repudiation services.

ISO/IEC 18014-2:2004 specifies mechanisms that generate independent time-stamps: in order to verify an independent time-stamp token, verifiers do not need access to any other time-stamp tokens. That is, time-stamp tokens are not linked, as is the case for the token types defined in ISO/IEC 18014-3.
