Identifying and analyzing Risk Mitigation strategies in IOT devices using Light Weight Symmetric Encryption Algorithms

Abstract

Internet of Things (IoT) is becoming more and more pervasive in all applications. It has greater capabilities like remote monitoring and control. Different available APIs make IoT devices and applications easy to develop and deploy. The data generated by IoT devices is smaller in size and needs light weight protocols like MQTT to carry it over the network. Risk Mitigation in IoT data is very crucial and to do that traditional security and risk mitigation algorithms like RSA, SHA-512 and all cannot be used as IoT devices have smaller data. Applying traditional security and Risk Mitigation techniques to IoT data by traditional algorithms will cause the computation overhead in IoT applications. Different Light Weight Encryptions schemes for risk mitigation are suggested like PRESENT, HUMMINGBIRD et al. in this paper, different light weight encryption algorithms used in IoT risk mitigation are studied and understood. Their problems are noted down and possible improvements are suggested to make them more efficient
