In this first part of ISO/IEC 18014, several things are explained and developed:
A "time-stamping service provides evidence that a data item existed before a certain point in time. "Time-stamp services produce time-stamp "tokens, which are data structures containing a verifiable "cryptographic binding between a "data item's representation and a time-value. This part of ISO/IEC 18014 defines "time-stamping mechanisms that produce independent "tokens, which can be verified one by one.
This part of ISO/IEC 18014:
ISO/IEC 18014-3:2004 describes "time-stamping services producing linked "tokens, that is, tokens that are "cryptographically bound to other tokens produced by these time-stamping services. It describes a general model for time-stamping services of this type and the basic components used to construct a time-stamping service of this type, it defines the data structures and protocols used to interact with a time-stamping service of this type, and it describes specific instances of such time-stamping services.
