Thus, the proposed system compared to the baseline and other technical solutions for a similar purpose provides improved reliability information security from unauthorized access. This is achieved by using complex signals with phase shift keying and duplex radio communication at two frequencies.
When this discrete information on the first modem is transmitted on frequency ω1=ωPR1=ωT2and received on frequency ω2=ωG1and the second modem, on the contrary, discrete information is transmitted on frequency ω2and received on the frequency ω1. The frequency of the local oscillators separated by twice the value of the second intermediate frequency
Protect transmitted information from unauthorized access has three levels: cryptographic, energy, and structural.
Cryptographic provincespecific special encryption methods, encoding and conversion information in which the content becomes unavailable without presenting key cryptogram and the inverse transform.
When the digital way to close the message being sent, which is implemented digital scrambler 15.1 (15.2), we can distinguish four main groups:
1) substitution symbols of discrete messages are replaced by other symbols in accordance with a predetermined rule;
2) the permutation characters of discrete messages perestanavlivaya by some rule within a specified block of the transmitted discrete messages;
3) analytical convert - encrypted message is converted by some analytical rule;
4) the combined conversion - source discrete message is encrypted by two or more methods of encryption.
The principle of operation of digital descrambler 29.1 (29.2) corresponds to a digital scrambler 15.1 (15.2), but has the opposite character.
Energy and structural levels provided by the use of complex signals with phase shift keying, which have high energy and structural secrecy.
Energy reserve data signals due to their high compressibility in time or range under optimal processing that poses the s to reduce the instantaneous radiated power. As a consequence, used complex QPSK signal at the point of reception may be masked by noise and interference. And energy complex QPSK signal is not small, it just spread across the time-frequency region so that at each point of this region is the signal power is less than the noise power and interference.
Structural secrecy FMN complex signals due to the large variety of their forms and significant ranges of parameter changes, which complicates the optimal or at least quasi-optimal processing complex QPSK signals priori unknown structure in order to increase the sensitivity of the receiver.
Complex signals with phase shift keying open new opportunities in technology transfer messages and protect them from unauthorized access. These signals allow you to apply a new type selection - structural selection. This means that there is a new opportunity to highlight the complex QPSK signals other signals and noise, operating in the same frequency band and at the same time. This feature is implemented by a convolution of the spectrum of the complex QPSK signals.
