FPGA based architecture for securing IoT with blockchain

Abstract

The Internet of Things (IoT) became widely utilized during last years, due to the large number of object that are connected to it - not only computers, but also humans, sensors and actuators. In the near future, a large number of objects will communicate to each other in a way never experienced before by the humankind. Connecting all these objects together will come with a wide area of challenges. One of the most important issues concerns trust. In majority of cases, centralized architectures are used to solve the problem, but the enormous number of object that can be connected in IoT will make almost impossible to manage and implement these solutions. Blockchain technology offers powerful solutions for decentralized architectures, which can be the future of IoT systems. A strong solution needs to be flexible to changes and must offer powerful resources to be successful. A hardware platform that uses FPGAs is suitable for those systems. In this paper we propose a solution for securing IoT systems using blockchain technology, implemented on a FPGA based architecture.
