Tiivistelmä
The recent proliferation of Internet of Things (IoT) has emphasized a lack of security and privacy in the industry. Many of the vulnerabilities stem from irresponsible practices committed by manufacturers and consumers alike and require a drastic paradigm shift to correct. The focus of this thesis is to understand how the Ethereum platform and blockchain technology can be utilized to bolster the security of the IoT sector. The proposed solution eliminates the need for trust by automating the workflow of devices through an interpreter that uses a distributed smart contract to determine its procedures. This form of indirect management allows a device to be hardened against internal threats by disallowing all incoming connections which significantly reduces the number of attack vectors that can be used to undermine a device’s integrity. While this solution does introduce an unprecedented level of security to a technological sector that is in dire need of it, an inevitable consequence is an increased cost of use and latency.
