HIDDEN ANTI-JAMMING NOTIFICATION METHOD AND SYSTEM Russian patent published in 2018 - IPC H04L9/00 G06F21/60 

FIELD: communication equipment; data processing.

SUBSTANCE: invention relates to telecommunications. Hidden anti-jamming notification method comprises interchanging secret keys K_steg and K_cryp between correspondents, open message M_i is pre-encrypted using key K_cryp, cryptogram C_i is obtained, k+r data channels are used for the transmission of the cryptogram, wherein the cryptogram is divided into k fragments c_i,1, c_i,2, …, c_i,k, which are interpreted as residues of some unknown number X_i. Excess residues are calculated c_k+1, …, c_k+r, further residues c_i,1, c_i,2, …, c_i,k+r by secure communication channels are sent to k+r pre-prepared sites. Trusted site environments store single-use steganography containers, in which steganography is used to embed residues. Filled containers are transferred to the network. At the subscriber points, the residues are extracted c*_i,1, c*_i,2, … c*_i,k+1, stages of their error-control decoding are performed and, if necessary, the faulty residues are corrected.

EFFECT: technical result is stealthiness and increased error-control of transmitted information.
