A Secure Cloud Computing Approach for Rapid Implementation of Public Key Cryptography on IoT Terminal Devices

Paper proposes a method for rapid implementation of public-key cryptography on IoT terminal devices with secure use of cloud computing, which allows increasing the security level due to multicomponent multiplicative-additive decomposition of a modified secret exponent code taking into account cyclic properties. A mathematical model of the proposed method has been developed and studied, allowing to obtain a quantitative assessment of the protection level. Theoretical calculations carried out using the developed mathematical model, as well as experimental studies have shown that the use of the proposed method allows to increase the protection level by 2-3 orders of magnitude compared to known solutions.
