Dan Petro & David Vargas: Vulnerabilities in the OSDP Protocol for Access Control Systems
A DEF CON 31 talk on security issues in the OSDP protocol — a newer encrypted standard designed to replace the legacy Wiegand protocol in access control systems.
The researchers present more than a dozen vulnerabilities that allow interception or bypass of access systems, including flaws in both cryptography and protocol implementation.
The talk also introduces a practical pentesting tool that can be connected to an RFID reader to exploit these vulnerabilities.
