METHOD OF HIDDEN TRANSFER OF CODED INFORMATION ALONG MULTIPLE COMMUNICATION CHANNELS Russian patent published in 2012 - IPC H04L9/00 

FIELD: information technologies.

SUBSTANCE: in the method secret keys are exchanged between correspondents, the open text is broken into blocks, they are coded with the help of a code with coupling of E¹ _k1 units on a key k₁, comprising elements e₁e₂e₃…e_n, as a result of which the first cryptogram C₁ is produced, made of m units, which are repeatedly coded with a code E² _k2 on the key k₂, as a result of which the second cryptogram C₂ is produced, comprising r units, in each unit C₂ during coding several blocks C₂ are placed, all units C₂ are numbered in a hidden manner, in n units C₂ n elements k₁ are placed, r units C₂ are steganographically hidden in r containers of different types using a key k₃, which identifies a container type and secret parameters of implementation logics, r containers are sent along several communication channels in compliance with an organisation chart and communication schedule determined by the key k₄.

EFFECT: higher cryptographic security of transferred information.
