CODING OF INFORMATION IN INFOCOMMUNICATIONS, AS ONE OF THE PROMISING AREAS OF INFORMATION PROTECTION

Abstract

The article reveals the principle of coding information in infocommunications, as one of the promising areas of
information protection. the main problems of information transfer and principles of formation of the protected channel of
information transfer in information and communication systems are defined. It is emphasized that in modern information and
communication systems modular presentation of information and encryption of information is widely used, when information
is encrypted on the transmitter side and decrypted on the receiver side. The block diagram of the information encoding system
for information protection in information and communication systems is shown, in which the interleaving of the symbols of
the transmitted message is used along with the noise-tolerant code. Encryption, decryption and interleaving operations are
described. It is noted that the interleaving procedure is to rearrange the characters of the codeword and restore the original
sequence after transmitting it on the channel. The algorithm of the system of complex information protection in information
and communication systems is offered, which is given in the form of a block diagram. The principle of operation of the system
of complex information protection is described in detail. Methods of presenting information on determining the level of
protection are substantiated. The action of the safety vector is described and the mechanism of presenting the result is formed.
It is emphasized that if the application of the signal of the complex information protection system in information and
communication systems leads to a positive result, then the graph is reflected by a vector with an upward direction; if the
application of the signal of the complex information protection system in information and communication systems ends in
errors, then the graph is reflected by a vector with a downward slope. Graphs of weight security accessories within the time
distribution of the system of complex information protection in information and communication systems are graphically
presented. It is emphasized that when using redundant coding, the set of memory elements can be considered as a channel for
transmitting information in information and communication systems, in which the latter is transmitted not in space but in
time.
