Internet of Things (IoT) are the first-class citizen of the 4th industrial revolution often called Industry 4.0. Security is of utmost concern when deploying IoT infrastructures. A majority of such deployments are centralized in nature and are much prone to several attacks such as DoS or DDoS, insider threats, etc. and are also vulnerable to a single point of failure. Such deployments rely on centralized cloud servers for identification, authentication, and storage of data generated by the IoT devices. Centralized architectures are in use for a long time with small to medium size IoT networks however, it may not be able to handle the requirements of the large-scale networks with billions of devices of tomorrow. Also, such systems lack transparency as users or organizations need to trust the way the cloud services store and use their data. Distributed technologies such as Blockchain along with Smart Contracts with the power of secure cryptography can help to solve a number of such challenges for better auditing, increased fault tolerance, and improve the overall security of such deployments. Integration of Blockchains with IoT based systems is still in its early phases and knowledge about them will give a researcher, or an industry practitioner an edge over others.
This tutorial is open to researchers, academicians, students and practitioners working in the area of IoT and blockchain technology, and anyone with interest in the topic. Participants can be from different backgrounds such as Security Analyst, people from audit and compliance sections, academic researchers, and so on. All of them need not be experts in the concerned Computer Science and Communications domain. From that point of view, the tutorial will begin with the very basics of the theories of cryptography and networks, and will subsequently move forward.
In this tutorial we will elaborate and emphasize the key aspects of the use of blockchain for IoT applications and will provide a platform to
