Timing analysis of the lightweight AAβ encryption scheme on embedded Linux for Internet of Things

Abstract

Internet of Things (IoT) is an interconnection of physical objects to the Internet which enables data exchange. When things are connected to the internet it becomes an open path for adversaries to unlawfully gain data over the internet leading to unaccountable security issues pertaining to data integrity and privacy. The need to secure the data gathered from sensors is important as this eventually gives trust to the larger data, the big data. Furthermore, connected objects in IoT are resource constrained through having smaller processors, storage capacities and battery power, thus putting constraints on the `Things' by imposing extra computation such as cryptographic computation. Instead of having a middleware secure connection, this paper proposes to implement a lightweight asymmetric encryption onboard the `Things' itself. Thus, this paper presents an analysis of a lightweight asymmetric encryption, the AAβ (AA-Beta) that might be feasibly implemented on the `Things' to secure the IoT networks.
