A lightweight authentication protocol for Internet of Things

The Internet of Things (IoT) refers to uniquely identifiable objects (things) which can interact with other objects through the global infrastructure of wireless/wired Internet. The communication technique among a large number of resource-constrained devices that generate large volumes of data has an impact on the security and privacy of the involved objects. In this paper, we propose an encryption method based on XOR manipulation, instead of complex encryption such as using the hash function, for anti-counterfeiting and privacy protection. The enhancement of the security is described and hardware design methodology is also demonstrated.
