FIELD: radio engineering, communication.
SUBSTANCE: method of authentication of a data hidden terminal transmission channel between two parties is characterized in that an unauthenticated data hidden terminal transmission channel is first created with the data channel end device on the first side and the data channel end device on the second side and the target application on the first side and the target application on the second side, where the end devices have at their disposal an unauthenticated shared secret code, and then on both sides of the data channel, the derivative data is calculated using unauthenticated shared secret code that are transmitted through external communication media outside the data channel to the two sides of the external authentication system, which then performs authentication of the sides involved in communication, including authentication of the data transmission channel. An external authentication system, which is a system, a set of programs and devices or an electronic service, is capable of independent authentication of users or systems.
EFFECT: increase in data transmission rate.
