1. Introduction
Automation of controlling systems, increasing the
requirements to their precision, operation speed and
information capability in combination with continuous
modernization of data reception and transfer
technologies are tightly bound with constant and
essential increase in information volumes that are
processed in controlling and information-communication
complexes. At the same time, multi-factorial character of
external actions on a technical system and diversity of
available ways to obtain an optimal final result implies,
in most of cases, presence of an operator when
controlling complex objects and technological processes.
As a result, sharply increased are the requirements
to quality of information resources and directly to
systems for reception, transmission, procession and
displaying the data. Disturbance of the main information
features – confidentiality, integrity and accessibility –
results in adoption of mistaken decisions and, as a
consequence, is related with casualty-producing
capacities and other undesired situations. Therefore,
protection of information in an ergatic system is
extremely important both at the stage of its creation and
in the operational process. Any used methods and means
should prevent the leak of protected information as well
as unauthorized and unintended influence on it [1, 2].
Essential progress in microelectronics provides
creation of new and rather accessible means and
methods to extract and attack information as well as
results in saturation of surrounding medium with diverse
electronics. As a result, software-hardware and
engineering support in information protection becomes
more and more topical. At the same time, organizational-
legal methods become less essential. In this situation, the
very task of information protection is rather difficult and
has no formal methods to solve it. The methodological
basis to solve tasks of this class can be provided by the
system approach that is based on investigation of an
object by using a respective model [2, 3]. But models of
ergatic optoelectronic systems aimed at investigation of
protectability of information circulating in them are
absent up to date.
This work is devoted to modeling and analytical
description of ergatic optoelectronic digital information-
controlling systems from the viewpoint how to protect
the processed data.
2. Conception
In a general case, modeling this system consists of
creation of some its image corresponding (with an
accuracy up to the purposes of modeling) to the
investigated object in order to obtain the necessary
characteristics of a real system by using this model. The
purpose determines principles for creation of this model,
which are realized as being based on the choice of a
respective set of criteria for system classification. In our
case, the task is to create a generalized model for a
human-machine optoelectronic system from the
viewpoint how to protect information circulated in it.
Here, to simplify the task we shall consider the
operator as a determinate element, assuming that his
parameters for processing the coming communications
and controlling actions on other system elements are
rigorously determined [4-7]. Our analysis of the used
principles for realization of mathematical models
enabled us to formulate the required set of main criteria
for description of the investigated optoelectronic ergatic
system [8-11].
1. A model-prototype relationship related with a level
of characteristics that are determined using this
model. Here, one should separate general and partial
models that are created to determine generalized and

local system parameters, respectively. It is obvious
that in our case we shall construct some general
model that will enable to study security
characteristics for the system in the whole.
2. A way for modeling that is determined by the
approach put into the basis of the built model. With
account of this sign, all the models can be separated
by two groups: analytical and statistical. The first
group is realized in the form of mathematical
dependences that allow analytical determining the
necessary system characteristics. While statistical
modeling is based on processing the results of
multiple imitation of the necessary dependences for
characteristics on external and internal system
parameters. For the level of a generalized model
representing the ergatic system, we shall use the
analytical way for modeling as the most efficient in
estimation of potential threats to this system as well
as in development of methods to overcome them.
3. The system type mainly dependent on the level of
certainty of interrelations between system
parameters both analyzed and influencing on them,
The same concerns parameters of system elements
and external medium. When modeling in accord
with this criterion, it is important to ascertain
whether this system is determinate or stochastic. As
to the first type, all the dependences are rigorously
and uniquely determined, while to the second type –
there is an essential influence of random factors on
them. In our case, the certainty in element
parameters used to reveal the most essential threats
to the optoelectronic system assumes application of
a determinate model.
4. A way of information representation, which depends
on values of variables and character of time running
in the system. Here, continuous, discrete and
combined models can be realized. Since the
constructed system representation uses digital
structures, the object parameters and time in the
model will possess a discrete character.
5. Linearity of the system related with validity or
invalidity of the superposition principle. In the
former case, the linear model is used, but in the
latter one – non-linear. At the used level of
generalization, we shall consider the ergatic
optoelectronic system as the linear one.
3. Model
Let us form some general analytic model for linear
determinate discrete optoelectronic system. As a
principle for separation of system objects, we shall use
the criterion of unchangeability in the information
representation form or functions for data conversion. In
this approach, our study should comprise all the
information structure from the communication source up
to the operator who is an ultimate data receiver [12, 13].
It is a most essential to analyze influence of
channels for information transfer between system
elements on processing the signals and their
transformation, as well as interaction of its elements
with surrounding medium. This representation of the
ergatic system is depicted in Fig. 1, where: 1 is the initial
information converter, 2 – channel for data transfer, 3 –
system for information processing, 4 – electro-optical
converter, 5 – channel for communication with the
operator, 6 – system operator, 7 – surrounding medium.
The element 1 of the system is a form-maker for the
information signal that is displayed after respective
processing and aimed at further reception by the operator in
the form of a message S . In a general case, its function is to
receive the necessary data IX from surrounding medium 7
and transform them into the signal form 0XD convenient for
transmission through the connection channel 2. This channel
is duplex and provides two-way exchange of messages
between the converter 1 and system 3 for processing
information. The element 3 processes information XD
received via the connection channel 2 and forms the signals
SE to control the electro-optic converter 4.

The latter converts the electrical signals SE into
the visual message 0IS , intended for man reception. The
converter 4 via the channel 5 is connected with the
operator 6. Using this channel, the optical information
signal is received by the operator in the form IS . In his
turn, the operator 6 has the possibility to act on
apparatus means in the system. The corresponding inter-
unit relations iC (where 6,1i ) describe control over
the elements 1 to 5 in this system by the operator 6.
Surrounding medium 7 provides multi-channel (w
channels) complex action on all the elements of the
ergatic system. Present here are both non-information
actions and those carrying a threat.
The structural matrix MSES of the considered
representation for the ergatic system depicted in Fig. 1,
from the viewpoint of information protection, is
quadratic and may be written in the following form

where 10SES lkM is the binary value that
corresponds to the relation between the k -th output of
the i -th system element and the l -th input of its j -th
element and is equal to unity when this relation is

The ergatic system shown in Fig. 1 and described
with the matrixes (1) and (2) is closed. It determines the
absence of a further (higher) level of representation that
could include the investigated system as an element of a
lower level. It is obvious that in this approach all the
objects influencing information security are really
represented in this analysis. That allows limiting this
consideration and modeling possible threats to
information with the determined level for this system.
3. Conclusion
The obtained expressions (1) and (2) reflect operation of
technical means aimed at visual transfer of data to the
operator, with account of essential (from the viewpoint
of information security) elements and relations, and
allow determining the most probable sources of threats
in the system as well. The offered mathematical
apparatus is a convenient analytical tool to investigate
information security in ergatic systems as well as to
choose the most efficient methods for information
protection, which is extremely important when creating
controlling and information-communication complexes
of both general and special purposes.
