Authentication on Internet of Things(IoT)

Abstract

Internet of Things (IoT) is a rapidly growing technology that is gaining importance in the area of ubiquitous computing. The main aim behind this concept is to provide communication capabilities to all the things present around us, so that these devices can communicate directly among themselves in an intelligent manner eliminating the need for human intervention. This communication is established by the use of RFID tags, sensors etc., which are provided with addresses to be uniquely identified and to communicate with each other. The main problem with IoT is providing security and privacy. Among many wireless technologies used for communication among devices, RFID technology is the most popular and widely used. Various factors like reduction in terms of size, weight, energy consumption lead to its popularity. So, in this thesis we mainly concentrate on RFID and its security problems. Since, RFID is a wireless communication technology; it is very easily prone to attacks and intrusions from the adversaries. So, we have to develop strong authentication algorithms which provide maximum security so that this technology can be used for the implementation of Internet of Things. But, the problem is that, RFID tags consist of very low tag resources in terms of memory and computational capabilities. It is very difficult to develop authentication protocols that consume minimum tag resources and provide maximum security. So, our goal is to develop lightweight authentication protocols which use simpler operations like XOR, Rot etc. which consumes very few tag resources and aims to provide maximum security.
