Post-Quantum Security for the Extended Access Control Protocol
Marc Fischlin, Jonas von der Heyden, Marian Margraf, Frank Morgner, Andreas Wallner, Holger Bock
Cryptographic protocols

The Extended Access Control (EAC) protocol for authenticated key agreement is mainly used to secure connections between machine-readable travel documents (MRTDs) and inspection terminals, but it can also be adopted as a universal solution for attribute-based access control with smart cards. The security of EAC is currently based on the Diffie-Hellman problem, which may not be hard when considering quantum computers. In this work we present PQ-EAC, a quantum-resistant version of the EAC...

Solving Terminal Revocation in EAC by Augmenting Terminal Authentication
Rafik Chaabouni
Public-key cryptography

In this paper we propose a solution to enable an accurate terminal revocation in the Extended Access Control (EAC). Chaabouni and Vaudenay in [CV09] pointed out the need for an accurate revocation procedure, but failed to provide a complete solution description. We aim at filling this gap. Our solution relies on augmenting terminal authentication with a t-out-of-l threshold signature provided by neighboring terminals. These terminals will be in charge of checking the revocation status of the...

Preventing Attacks on Machine Readable Travel Documents (MRTDs)
Gaurav S. Kc, Paul A. Karger
Applications

After the terror attacks of 9/11, the U.S. Congress passed legislation that requires in the US Visa Waiver Program to begin issuing issuing machine readable passports that are tamper resistant and incorporate biometric and document authentication identifiers. The International Civil Aviation Organization (ICAO) has issued specifications for Machine Readable Travel Documents (MRTD) that are equipped with a smart card processor to perform biometric identification of the holder. Some countries,...
