Secure data transaction and data analysis of IOT devices using blockchain

Abstract

The Internet of Things (IOT) is a network formed by electronic objects which have embedded sensors, software and network connectivity in them. They can collect and exchange and are prone to both cyber-attack and physical tampering. Thus, it is essential to encrypt their communications, by addressing new challenges such as impersonating "things" or nodes, denial-of-sleep attacks that drain batteries, to denial-of-service attacks (DoS). A peer-to-peer model can eliminate the dependency of a centralized data center. A Blockchain is a model for a distributed database of records of all transactions or digital events that have been executed and shared among participating nodes. In it, digital signatures are validated instead of physical signatures. With a decentralized approach implemented through cryptographic algorithms, blockchainoversees a secure transaction betweenIOT devices and coordinate them. This paper explores one of the process of incorporating blockchain with a very vulnerable centralized IOT data transactions. IOT devices are represented as Aircrafts in which the engine data and various data from the aircrafts’ sensors are sent to the airports for analysis. After analysis, the analyzed data is sent to nearby airports and also to that particular aircraft. The paper analyzes how the blockchain network is created, the time latency of sending the data of the IOT devices through this blockchain network and some parts of the analysis process which is required for the Aircraft maintenance.
