Security of the Positioning Systems

Series: Department Seminar

Speaker: Mridula Singh, Faculty CISPA Helmholtz Center for Information Security Saarbrucken, Germany

Date/Time: Jan 08 11:00:00

Location: CSA Seminar Hall (Room No. 254, First Floor)

Abstract:
A wide variety of applications, such as modern payment systems, access control for critical infrastructures, healthcare, and contact tracing depend on location and proximity information. There are multiple ways to establish physical distance between two entities, most of which are prone to distance modification attacks and can lead to loss of property (e.g., cars with keyless entry systems) and human life (e.g., vehicle collision). The increasing need for secure distance measurement has motivated academia and industry to explore new secure designs and integrate them into the upcoming standards, including IEEE 802.15.4z (Ultra-Wideband), IEEE 802.11mc/az (WiFi), and 3GPP 5G, and OSNMA in Galileo. In this talk, I will discuss the security vulnerabilities of the ranging and positioning design proposed in these standards.

Speaker Bio:
Mridula Singh is (tenure-track) Faculty at CISPA – Helmholtz Center for Information Security in Saarbrucken, Germany. She is interested in Wireless and System Security, focusing strongly on autonomous cyber-physical systems. Her interest in designing physical layer Message Time of Arrival Codes establishes the foundation of secure proximity-based access control and positioning systems. This work has been instrumental in enabling secure passive keyless entry and start systems of various car models. She is currently exploring the possibility of designing secure communication and positioning systems. She co-founded Trishulam while pursuing her masters degree. She worked as a research engineer at Xerox Research Center India, where she was involved in smart transportation and healthcare projects. She received her masters degree in computer science from IIIT-Delhi, India, and her Ph.D in Computer Science from ETH Zurich, Switzerland.
