Abstract
Internet of things is a concept that interrelates the devices that are connected to one or the other network for the purpose of exchanging the data with the other systems and devices without the necessity of human to machine interaction. Nowadays, privacy and security are the two major concerns in IoT and also the crucial security requirements of IoT cannot be guaranteed by the existing security structures due to the restraints in memory and CPU of the IoT devices. There is also another disadvantage which is the centralized security architecture which means to a database that is located or situated at a single point or single server but whereas it has a limitation of single point of attacks and also defending against this limitation is very costly. So a decentralized security architecture is required for IoT and it is designed in such a way that it meets the limitations caused by the centralized security architecture. So an important concept called Blockchain comes into the picture where the Blockchain is a decentralized security architecture which is very much suitable for different applications. However, Blockchain is not suitable in its original form due to low scalability and high complexity. So we propose a Sliding window blockchain architecture which helps in many ways such as in modifying the traditional Blockchain architecture to suit IoT applications. This proposed Sliding window blockchain architecture will make use of previous blocks to form the has h of the next block and also the hash values altogether are responsible in sliding window block chain architecture performance is analysed on a real time data stream generated from smart home testbed. Finally, the overall results shows the advantages of this proposed Blockchain architecture that is increased security and minimization of the memory overhead.
