The method of increasing the security of IoT devices by implementing the dynamic change of the Bluetooth address

Abstract

The paper examines the possibilities of use and vulnerability of devices that, according to the concept of construction and use, belong to the Internet of Things. Modern technological solutions for collecting and transmitting primary data mostly focus on Internet of Things devices. They are actively used in various spheres of industry and everyday life. At the same time, the low price, technological limitations and the lack of uniform standards affected their security level. There are known cases when attackers, exploiting the vulnerabilities of Internet of Things devices, launched an attack on the company's information system and caused financial and reputational damage. Typical solutions for the construction of IoT systems, in most cases, allow attackers to implement attacks on vital components of such systems and create a threat to the lives of users, causing reputational and financial losses. Such devices are connected to the control unit with Bluetooth technology and are identified by the name of the device and its Bluetooth address. These parameters are the main vector of the intruder's attack on Internet of Things devices. The paper proposes a method of increasing the level of security of IoT devices by introducing a dynamic change of the Bluetooth address. The central control unit of the Internet of Things devices will initiate the process of dynamic, random over time, change of the Bluetooth address of the devices, which will limit the time interval of possible influence of the attacker on the device.
