Abstract:
The research on Internet of Things (IoT) devices has advanced tremendously over the past few years. IoT-based systems have their applications in almost every sphere of human life. Modern IoT devices are of quite heterogeneous nature and they are going to be involved in every thing from turning home lights ON/OFF to handling life critical data of a patient in smart health system. Because of the amount and nature of the data handled by IoT devices, they are a lucrative target for various kinds of security attacks. Among the many countermeasures against the security threats, Advanced Encryption Standard (AES) is a popular cryptographic scheme as it offers robust and platform independent implementation. In this work, keeping in view of the heterogeneous nature of target IoT devices, we explore five different implementations of AES algorithm. These implementations use different algorithmic and architecture optimizations. The results obtained through these implementation reveal that some of them are very suitable for resource constrained edge IoT devices while others are useful for performance hungry middle layer gateways of an IoT-based system. Experimental results reveal that in an IoT-based system, a uniform cryptographic implementation should not be considered and that the implementations should be altered as per the nature of target device.
