Foreword
This European Telecommunication Standard (ETS) has been produced by the Special Mobile Group
(SMG) of the European Telecommunications Standards Institute (ETSI).
This ETS defines security features within the digital cellular telecommunications system.
The specification from which this ETS has been derived was originally based on CEPT documentation,
hence the presentation of this ETS may not be entirely in accordance with the ETSI/PNE Rules.

1 Scope
Bearer and Teleservices, as respectively defined in GSM 02.02 and GSM 02.03, are the objects which the
GSM PLMN operators offer to their customers. Besides these basic telecommunications services,
features which aim at up-grading these basic services need also to be offered. Due to the use of
radiocommunications in a PLMN, which are of a special nature compared to classical distribution
transmission techniques used in the fixed networks, such a category of features is related to security
aspects.
In a GSM PLMN, both the users and the network operator have to be protected against undesirable
intrusion of third parties. However, measures should be provided for in order to insure maximum
protection of the rights of the individuals concerns. As a consequence, a security feature is either a
supplementary service to Tele or Bearer services, which can be selected by the subscriber, or a network
function involved in the provision of one or several telecommunication services.
The purpose of this European Telecommunication Standard (ETS) is to define the security features which
are to be available in a GSM PLMN, together with the associated levels of protection. This ETS is only
concerned with those security features which aim at the up-grading of the security in a GSM PLMN. In
particular, end-to-end security is outside the scope of this ETS.
The implementation aspects of security features are described in GSM 03.20.

2 General
The use of radiocommunications for transmission to the mobile subscribers makes PLMNs particularly
sensitive to:
- misuse of their resources by unauthorised persons using manipulated Mobile Stations, who try to
impersonate authorized subscribers; and
- eavesdropping of the various information which are exchanged on the radio path.
It can be seen that PLMNs intrinsically do not provide the same level of protection to their operators and
subscribers as the traditional telecommunication networks provide. This fact leads to the need to
implement security features in a GSM PLMN in order to pro
