The method in question has certain advantages over the state-of-the-art methods both from the point of view of functionality (it demonstrates universality and integrated approach to protection) and performance (high speed of information processing, the guaranteed reliability in any channel, high percentage of corrected errors).Universality is understood as applicability in any data memory bank and in any communication channel (with various interference rates and the law of interference distribution).Integrated approach to the protection problem is understood as possibility to protect the information at various kinds of impact within the framework of a single algorithm of information processing and at one-time redundancy introduction.
The method is based on new codes for restoration of integrity of the information - stochasticcodes, i.e. the errors correction with the preset accuracy.
Encoding of codes with restoration of information integrity is reduced to application of any binary (n, k)-code with correction of the errors, described by verification matrix Н and the code distance d, in the form of l-interlacing code blocks, where l the binary symbols with the same name are considered to be a q-ary symbol (q=2l); each q-ary symbol, prior to transmission to a channel, is subject to randomization (stochastic transformation) with randomization parameter changing for each new symbol. Randomization operation is carried out by Shannon rules of cryptography.
Correction of errors is carried out by the rule of maximum accuracy, unlike the principle of maximum credibility used in the theory of coding, which principle is reduced to allocation, from all possible vectors of errors, of such vector, which "is the most credible" in the type of channels used.
One may speak of “maximum benefit” (ultimate probability of message delivery, minimal probability of decoding error, minimal probability of inflicting false information, minimal probability of cracking the context of a confidential message) at minimal investments (introduction of minimal redundancy, required complexity of processing, minimal delay time)
Speed of decoding is up to 50 Mb/sec and practically does not depend on the code parameters and on the probability of error appearance.
Speed of direct stochastic conversion is
77 097 312 bit/sec.
Speed of reverse stochastic conversion is
0.962Transmission rate at selecting the optimal values of code with error correction
