METHOD FOR CONVERTING DATA WITH EQUAL-PROBABLE INITIALIZATION Russian patent published in 2017 - IPC H04L9/16 

FIELD: physics.

SUBSTANCE: method for converting data with equal-probable initialization based on the use of probable encryption, which consists in forming a pseudo-random sequence, to which the block of the original message is attached to form an extended message block, and then performing its crypto-conversion, the result of which is transmitted on the communication line to the subscriber. Then, the reverse crypto-conversion is performed to obtain an extended message block, from which a pseudo-random sequence is eliminated to obtain a block of the original message, while mixing the bits with changing their locations before the crypto-conversion, and after the reverse crypto-conversion, the bit locations in the extended message block are restored.

EFFECT: increasing the security level of the cryptosystem by reducing the apriori knowledge of the attacker, when using the probable encryption.
