Time-Memory Trade-Offs Sound the Death Knell for GPRS and GSM (2024)
Presentation / Conference Contribution
Avoine, G., Carpent, X., Claverie, T., Devine, C., & Leblanc-Albarel, D. (2024, August). Time-Memory Trade-Offs Sound the Death Knell for GPRS and GSM. Presented at Advances in Cryptology – CRYPTO 2024, Santa Barbara, USA

This paper introduces a practical TMTO-based attack against GSM (A5/3) and GPRS (GEA-3), which are both technologies used in 2G mobile networks. Although designed in the 80 s, these networks are still quite active today, especially for embedded syste... Read More about Time-Memory Trade-Offs Sound the Death Knell for GPRS and GSM.

Element Distinctness and Bounded Input Size in Private Set Intersection and Related Protocols (2024)
Presentation / Conference Contribution
Carpent, X., Hwang, S., & Tsudik, G. (2024, March). Element Distinctness and Bounded Input Size in Private Set Intersection and Related Protocols. Presented at Applied Cryptography and Network Security, Abu Dhabi

This paper considers Private Set Intersection (PSI) protocols where one party (server) imposes a minimum input size (lower bound) on the other party (client), and the latter wants to keep its input size private. This entails tackling two types of pos... Read More about Element Distinctness and Bounded Input Size in Private Set Intersection and Related Protocols.

Enabling Vehicle-to-Vehicle Trust in Rural Areas: An Evaluation of a Pre-Signature Scheme for Infrastructure-Limited Environments (2024)
Journal Article
Almani, D., Muller, T., Carpent, X., Yoshizawa, T., & Furnell, S. (2024). Enabling Vehicle-to-Vehicle Trust in Rural Areas: An Evaluation of a Pre-Signature Scheme for Infrastructure-Limited Environments. Future Internet, 16(3), Article 77. https://doi.org/10.3390/fi16030077

This research investigates the deployment and effectiveness of the novel Pre-Signature scheme, developed to allow for up-to-date reputation being available in Vehicle-to-Vehicle (V2V) communications in rural landscapes, where the communications infra...

Pre-Signature Scheme for Trustworthy Offline V2V Communication (2023)
Presentation / Conference Contribution
Muller, T., Carpent, X., Furnell, S., Almani, D., & Yoshizawa, T. (2023, October). Pre-Signature Scheme for Trustworthy Offline V2V Communication. Presented at 14th IFIP International Conference on Trust Management (IFIPTM 2023), Amsterdam, Netherlands

Vehicle-to-Vehicle (V2V) communication systems hold great potential for enhancing road safety and traffic efficiency. The authenti-cation of such communication is crucial, particularly in scenarios where infrastructure is absent, while also ensuring...
