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 E1Çèk1 units on a key k1, comprising elements e1e2e3Çen, as a result of which the first cryptogram C1 is produced, made of m units, which are repeatedly coded with a code E2Çèk2 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. ^ 6 cl, 11 dwg, 3 tbl, 2 ex |
