Appendix II

Use case of creating trusted environment for rescue systems
(This appendix does not form an integral part of this Recommendation.)

This Appendix describes an example of forming trusted environment in the domain of ensuring the safety of
people in emergency situations.

Nowadays it is not easy for a person to navigate in technological environment. This problem becomes
extremely actual in the case of an emergency, when the wrong action or procrastination leads to human
victims. The use of modern ICT to create a different kind of warning and safety systems to assist the
evacuation process can improve the safety of people in the case of an emergency.

Moreover, services of safety systems (e.g. notification, evacuation management) should be provided in
trusted environment. This is related to a direct threat to human life or his activity that occurs in the case of
an unwanted effect from the interaction or security breach in the environment.

The basic properties of trusted environment can be implemented in safety systems as follows:

Predictability: it is required to inform users about the possible operation scenarios of the system, the types
of information provided by this system (audio, video, text or tactile messages) and its mission. It is required
to pre-define the alarm messages and introduce to the users the verity of possible alarm messages. In the
process of evacuation the system is required to use only familiar to users evacuation plans to minimize the
perception time of information and avoid any delay that could lead to human victims.

Information security: It is required for the integrity and availability of warning signals, information about the
evacuation process and other vital information in an emergency to be guaranteed for all users of the system.

Interoperability: all users of the system is required to be able to receive alarm messages and other
information via any of the established public communication channels (cellular, radio and television
broadcasting, Internet, etc.) and with any of available devices (mobile phone, smart phone, TV, etc.). It is
required for the alarm messages and other emergency information to be provided for both residents
(employees) and non-residents (visitors) in the appropriate language.

Availability of administration services: continuous customer support is required to be provided for all users
of the system (residents, workers, visitors, etc.) in terms of assistance in safety related issues. All actions and
instructions of the system is required to be recorded in a special vault (black box) in order to allow further
establish their eligibility.

The basic principles of safety systems in trusted environment can be described as follows:

The principle of non-discrimination – in security systems based on ICT electronic alerts and evacuation
instructions in case of emergency is required to have the same legal force and the same level of responsibility
as the direct commands of rescue services.

The principle of technological neutrality – the information from the security system is required to be
provided using all available for users technologies (see Interoperability).

The principle of functional equivalence – in security systems based on ICT electronic alerts and evacuation
instructions in case of emergency is required to be equivalent to the direct commands of rescue services.

The principle of unification – the substantial part of the information from security system is required to be
independent on transmission technology used in the communication channel.
