Information technology. Security techniques. Time-stamping services - Mechanisms producing independent tokens Ingestion-build-48974 ISO 21940‑1 is the first1 Scope This part of ISO IEC 18014 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. This part of ISO IEC 18014
