FIELD: information technologies.
SUBSTANCE: invention refers to data transmission, specifically to effective cryptographic data transmission in real-time security protocol. Transmitting terminal can be used for data decoding with session key received from bitstream. Bitstream can be transmitted with head information to transmitting terminal. To maintain bandwidth the information can be divided into parts, and each part is transmitted with encrypted data package. Transmitting terminal can be used for restoration of bitstream from information parts comprising package headers, and use of bitstream for session key receiving. Session key can be used for data decoding.
EFFECT: higher cryptographic security of transferred data.
