FIELD: technology for controlling safe transmission of data between user module and safety module.
SUBSTANCE: in accordance to invention, problem is solved by using a method, including following operations: checking, on the side of user module, whether safety module is in coupling condition; if that condition is satisfied, unique coupling key is utilized, specific for couple user module/safety module for encryption of data exchanged between these modules; if aforementioned condition is not satisfied, than a request is dispatched to control center to authorize coupling with safety module, to which identification of user module and safety module is attached; in control center, competence of request is verified and result is transferred to user module; during receipt of authorization, coupling key is generated, unique for couple user module/safety module for encryption of data exchanged between these modules.
EFFECT: prevention of unsanctioned access to information while making it possible to couple current safety module with other user modules.
