METHOD OF PROVIDING TRANSMISSION OF ENCRYPTED DATA IN A DIGITAL DATA TRANSMISSION SYSTEM (VERSIONS) Russian patent published in 2019 - IPC H04L9/12 

FIELD: computer equipment.

SUBSTANCE: invention relates to the computer equipment. Method of transmitting encrypted data in a digital data transmission system, wherein if variables are not initialization in a computer sending security messages, initialization of variables, reading the current time value from the timer of the computer sending the protected messages, if the current time value from the timer is greater than or equal to the sum of the time for sending the previous service frame and the time interval between the service frames, then sending the service frame, otherwise, if there is a frame of data requiring sending, then processing this frame, if in the computer receiving protected messages, initialization of variables is not carried out, then resetting the flag, receiving the next frame from the computer sending the protected messages, determining the type of frame, if the frame at the input of the computer receiving the protected messages is a service frame, the value of the synchronization burst is extracted from the service frame, the simulated service packet is checked, otherwise, if the frame at the input of the computer receiving the protected messages is not a service frame, the frame is deleted, otherwise the imitation of the frame is checked.

EFFECT: high efficiency of decrypting data frames.
