Open-source Secure NFC-based Physical Access Control System using EV2 Mutual Authentication

Abstract

[Abstract]: Currently, physical access control is dominated by private and proprietary solutions that are closed, inflexible and often insecure. To address these shortcomings, this work presents an open-source, modular NFC-based access control system. The system consists of two modules. First, a hardware module, capable of reading NFC NTAG424 cards and unlocking a magnetic lock has been assembled. Second, a centralized management server, with an administration panel. The system supports Enhanced Version 2 mutual authentication protocol, time-based and role-based policies, allowing administrators to protect multiple zones within the same facility from a centralized management server. This open solution provides a secure and cost-effective alternative that seeks greater transparency and control.
