Novel lightweight interactive IoT end device architecture with tight security intelligence confidentiality, integrity, authenticity and availability

IoT end devices are resource deficient due to least processing power and footprint therefore need lightweight resources for optimum performance and optimum footprint. But presence of unsecure world and unsecure operating system in the existing architectures (Guan et al., 2017; Pinto in IEEE Internet Comput 21: 40–47, 2017; Zhang in Futur Gener Comput Syst 88:16–27) make the IoT devices over-architectured and over-interactive hence performance overhead and unsecure. Unlike existing architectures in this paper our proposed architecture does not use any operating system and apply lightweight µ-visor at the fog and lightweight s/w layers at the IoT edge over ESP32 microcontroller using Arduino IDE so as to exclude over-architecture hence lightweight. Lightweight architecture must include minimum trusted computing base therefore least surface area for attack hence least number of bugs thus secure. Our architecture also incurs security intelligence both at IoT edge and fog since boot till s/w stack upload. Security intelligence confirms intra-device security in terms of confidentiality, integrity, authenticity and availability (CIAA). In our architecture Secure IoT algorithm uses 64 bits key thus optimizes encryption decryption process. Communication between IoT edge and fog is also governed by communication security intelligence. This paper finally compares over-architectural and security issues among existing and proposed architectures using graph hence validate that proposed architecture is lightweight, interactive and equipped with tight security intelligence CIAA.
