This document (EN 419231:2019) has been prepared by Technical Committee CEN/TC 224 “Personal
identification, electronic signature and cards and their related systems and operations”, the secretariat
of which is held by AFNOR.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by February 2020, and conflicting national standards shall
be withdrawn at the latest by February 2020.
Attention is drawn to the possibility that some of the elements of this document may be the subject of

European Free Trade Association.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,

Introduction
This document specifies a protection profile for a software component that is part of time stamping
system that provides time-stamp tokens to requesters. The TOE operational environment is composed of
an operating system, other software applications, drivers and an external UTC time source that is
considered to be trusted by the TOE. When a cryptographic module is being used, it is outside of the TOE
perimeter.
The TOE is expected to be protected by physical and organisational protection measures implemented
by the TOE environment. Those measures are expected to restrict the TOE physical access (e.g. for
administration purposes) to authorized persons only and are expected to require dual control.
ETSI EN 319 421 specifies additional policy and security requirements relating to the operation and
management practices of TSPs issuing time-stamps.
This protection profile is issued by the European Committee for Standardization, Information Society
Standardization System (CEN/ISSS).

3.1.1
Coordinated Universal Time
UTC
time scale based on the second as defined in TF.460-6
Note 1 to entry: For most practical purposes UTC is equivalent to mean solar time at the prime meridian (0°).
More specifically, UTC is a compromise between the highly stable atomic time (Temps Atomique International -
TAI) and solar time derived from the irregular Earth rotation (related to the Greenwich mean sidereal time (GMST)
by a conventional relationship).
