A Kerberos based secure communication system in smart (internet of things) environment

Abstract

Over recent years, Internet of Things (IoT) has experienced a spectacular growth which is captivating the researchers to carry out their research towards the digitization of the physical world. An innumerable number of devices are deployed at various geographical locations to access data. These end nodes are extremely constrained in terms of power and processing capabilities. Traditional cryptographic and security algorithms require high computation and processing capabilities. The hardware specifications of these devices limit this mechanism, as it is too heavy to be handled by these low constrained nodes computationally. The solution to this is to use a lightweight authentication mechanism. Kerberos is one such authentication mechanism which uses symmetric key cryptography.
