A Sliding Window Blockchain Architecture for the Internet of Things

The Internet of Things is a concept that allows people to connect to the Internet and access services through new, unconventional computing and communication practices. But there are two issues in the Internet of Things. These are security and data protection. Due to the limited processor, storage, and energy resources of IoT devices existing security frameworks are unable to meet the essential security requirements. Centralized security is not good for IoT as they tend towards a single point of failure and are more expensive for protecting centralized resources against attacks. Therefore, decentralized IoT security must be adapted. Blockchain is a a decentralised security system that can be used to secure many different things. Blockchain is not currently appropriate technology for IoT because it is too complicated and poorly scalable. This paper shows research on and implementation of Sliding Window Blockchain (SWBC), a conventional blockchain architecture used in Internet of Things applications. SWBC's performance is computed using live data which is supplied by a smart home testbed.
