Шаблон:Use British (Oxford) English ISO/IEC 18014 Information technology — Security techniques — Time-stamping services is an international standard that specifies time-stamping techniques. It comprises four parts:

• Part 1: Framework
• Part 2: Mechanisms producing independent tokens
• Part 3: Mechanisms producing linked tokens
• Part 4: Traceability of time sources

Part 1: Framework

In this first part of ISO/IEC 18014, several things are explained and developed:

• The identification of the objectives of a time authority.
• The description of a general model on which time stamping services are based.
• The definition of time stamping services.
• The definition of the basic protocols of time stamping.
• The specifications of the protocols between the involved entities.

Key words: audit, non-repudiation, security, time-stamp

Part 2: Mechanisms producing independent tokens

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.

Part 3: Mechanisms producing linked tokens

This part of ISO/IEC 18014:

• Describes a general model for time-stamping services producing linked tokens.
• Describes the basic components used to construct a time-stamping service of this type.
• Defines the data structures used to interact with a time-stamping service of this type.
• Describes specific instances of such time-stamping services.
