FIELD: physics.
SUBSTANCE: invention relates to the field of terminal technologies, namely to circuits of communication with data storage devices and their control. For this purpose, the data storage device for the mobile device includes a safety element and a controller connected to the safety element. Security element includes data and is configured to process them. At the same time between the mobile device and the controller there is a first data exchange line, and between the safety element and the controller there is a second data exchange line. Controller, in its turn, is configured to receive requests from the mobile device, receive responses from the security element, determine the current operating status of the security element, generate and send requests to the security element and generate and send responses to the mobile device.
EFFECT: data storage safety.
