  1. ; ; (, REUNS 2022: The 8th National Workshop for REU Research in Networking and Systems)
    In this study we explore the use of blockchain with IoT devices to provide visitor authentication and access control in a physical environment. We propose a “bracelet” using a NodeMCU that transmits visitor location information and cannot be removed without alerting a management system. Our results show that the proposed system has noticeable improvements over a similar system proposed last year, increasing the practicality of implementing such a system.

    In this work we explore the use of blockchain with Internet of Things (IoT) devices to provide visitor authentication and access control in a physical environment. We propose 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. We present the design, implementation, and testing of our system. Our results show the feasibility of implementing a physical access control system based on blockchain technology, and performance improvements over a similar system proposed in the literature.

  3. ; ; (, 2021 National Symposium for NSF REU Research in Data Science, Systems, and Security (REU 2021 Symposium) - Together with 2021 IEEE BigData Conference)
    This study applies the high data integrity that comes with blockchain technology towards authentication and access control for visitors of a physical facility. The use of smart contracts on an Ethereum based implementation of the blockchain allows for smart contract code to handle both access control and visitor authentication at scale. Javascript code executed off the blockchain enables the system to interact with and parse through the blockchain data. The proposed system is scalable, applies to multiple use cases, and mitigates issues a centralized approach faces.
