Secure Data Exchange Technologies in Mobile and IoT Devices

When transferring keys, passwords, authentication or personal data between mobile or IoT, there is a risk of information leakage. Standard radio transmission channels contain many vulnerabilities, difficulties in developing certification of the received tools. Optical means are sensitive to camera quality, screen condition, illumination, etc. The issues of acoustic information transmission are considered. The article is devoted to making a decision on choosing a suitable information transmission system depending on the transmission conditions and level of protection. Optical and acoustic transmission channels are chosen as the basic system.
