Internet of Things Security: A Blockchain Perspective

Abstract

Since the arrival of computers in 1950s, technology has leaped over many generations at a rapid pace. Computers have found their use in every human activity, namely scientific experiments, industries, transportation, medicine, healthcare, home management, etc. Internet of things (IoT) is one such computing paradigm that aims to assist and automate various trivial and non-trivial aspects of these activities. IoT generates a huge amount of data at a fast rate. The data can be trivial, personal, or sensitive to someone or an organization. Hence, securing IoT data and its aggregation is of utmost importance. The paper gives a brief introduction of IoT in terms of its security aspects to understand the various facets of malicious attacks possible on it. Then, how blockchain, an ever-popular security suite, can be used to provide security to IoT in its various integrations is presented. Finally, some future research issues are discussed towards blockchain-IoT future.
