ISO/IEC 18014 Information technology — Security techniques — Time-stamping services is an international standard that specifies time-stamping techniques.
It comprises four parts: In this first part of ISO/IEC 18014, several things are explained and developed: Key words: audit, non-repudiation, security, time-stamp 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.
