Peker, Hearst Team with Colleagues to Publish Study on Use of Blockchain with IoT Devices

A new study by Yesem Kurt Peker, an associate professor in CSU’s TSYS School of Computer Science, and Jarel Hearst, a senior student in the TSYS School majoring in game design, explores the use of blockchain with Internet of Things (IoT) devices to provide visitor authentication and access control in a physical environment. Their approach, developed with Frederick Stock of the University of Massachusetts – Lowell and Alfredo Perez of the University of Nebraska – Omaha, proposes the use of a “bracelet” based on a low-cost NodeMCU IoT platform that broadcasts visitor location information and cannot be removed without alerting a management system.

The study, which appears in the current issue of Cryptography, not only presents the design of their system, it also provides tests of its implementation. As they report, the results support the feasibility of implementing a physical access control system based on blockchain technology, given its superior performance compared to a similar system proposed in a prior academic study.

In addition to being a member of eSports team at CSU, Hearst holds a certification in deep learning from NVIDIA. Set to graduate from CSU in 2023, he aspires to become an independent game designer who works toward improving games in ways that make them easier to learn while also maintaining an adequate level of difficulty. A native of Douglasville, Georgia, Hearst also aims to complete an internship in computer science wherein he would work in both computer hardware and computer software.
