COVERT CHANNELS GENERATED BY TAGS.
- N. A. Grusho IPI RAN, email@example.com
Abstract: A possibility of creation of covert channels by means of the tags determined
by admissible changes of the form of electrical signals is researched. Existence of
identified admissible changes of the formof electrical signals is shown. The algorithm
of creation of the covert channel with the check group reducing probability of the
wrong decoding of hidden transmission is considered. It is shown that the number of
the transferred hidden messages is commensurable with number of messages in legal

Abstract: Creation of the powerful centralized centers of attacks detection, servicing a large
number of clients, possesses obvious positive properties. However, such systems
generate a new class of the attacks connected with a need to service a flow of
incidents, arriving from different clients. Such flow can generate a queue preventing
effective detection of attacks. These problems are described by queue models. Some
results of attacks simulation by means of queuing systems are presented.
Keywords: information security; queuing systems; intrusion detection
ON A METHOD OF RELIABLE DELIVERY AND DATA SOURCE
VERIFICATION WITHIN A CLIENT–SERVER INTERACTION
OVER AN OPEN COMMUNICATION CHANNEL.
- E. V. Piskovskiy Moscow Institute of Physics and Technology (State University),
Abstract: Two models of client - server interaction are considered: a model to describe reliable
data delivery over an open channel and a model to describe data source verification.
The models are formulated based on a set of rules to resolve the conflicts when
several clients are connecting to one server. A computer-appliance is suggested for
testing the functionality of the models either allowing several connections to the
server from multiple clients or blocking connections from multiple clients.
Keywords: client - server interaction; two-factor authentication; information source
verification; reliable data delivery; open channel

INTO THE DATA PACKAGES HEADERS.
- M. I. Zabezhailo Applied Research Center for Computer Networks, Moscow, Skolkovo,
Abstract: The possibility to apply models and techniques of the Software Defined Networks
(SDN-technologies) to optimize traffic control in computer networks is discussed.
An algebraic formalization for the problem of subwords inclusion into the words over
the given alphabet is suggested. There are analyzed problem-oriented conditions
and algorithms that implement and optimize checking for limited length subwords
(subsequences) inclusion into the lines of big switching tables. Some additional SDN-
based abilities to speed up data processing in computer networks are demonstrated.

Abstract: The paper is dedicated to improvement of perfomance charachteristics of existing
malicious network traffic analyzing algorithms on high-speed network interfaces.
The Racewalk algorithm is considered as a base for research. The authors focus on
offloading certain processing actions into specific dedicated hardware device. As
seen from experimental results, such implementation can work on higher network
interface speeds (i. e., 10 Gbit/s).

- A. A. Khoroshilov Center of Information Technologies and Systems for Executive Power Authorities,
Abstract: A method for generation of the formalized semantic content of a document and
its visual representation, a semantic map of the document, is described. The
formalization of the document content is based on the application of the semantic
and conceptual analysis methods ensuring definition of the conceptual content of the
text and the assignment to concepts of characteristics consistent with their semantic
role and significance in the text. The resulting semantic structure of the text is
converted to its visual representation showing the relationships between objects,
events, and themes.
Keywords: formalized semantic description of the document; document semantic
map; semantic analysis; conceptual analysis; analysis of conceptual content of the
document; knowledge extraction from texts
