METHOD OF TRANSMISSION AND COMPLEX PROTECTION OF INFORMATION Russian patent published in 2009 - IPC G06F11/00 H04L1/20 H03M13/35 

FIELD: physics; computer engineering.

SUBSTANCE: method of transmission and complex protection of information is characterised by that, at the transmitting side, before transmission of information, channel type and quality are determined, optimum values are chosen for parameters n, k and m of the used stochastic q-ary (n,k,q,m)-code based on the initial binary (n, k)-code with 1-alternation (q=2¹), where n, k - are parameters of the initial binary code, q - is the code base, m - is the number of repetitions of the code block with equal values of the information part. Information is encoded using the chosen stochastic q-ary code. Direct randomisation of q-ary symbols is done. Reverse randomisation of q-ary symbols is done at the receiving side. Integrity of q-ary symbos is monitored, authenticity of integrity of q-ary symbols is monitored, integrity of q-ary symbols is restored from m code blocks, accumulated for issuing the user with authentic q-ary symbols after processing m code blocks, optimality of values of parameters n, k and m is monitored and their values are corrected.

EFFECT: provision for stable exchange of information over a channel with independent characteristics and maximum effective information transmission speed for the given channel, closer to the channel carrying capacity.
