Security research - recent highlights

The paper ARPKI: Attack Resilient Public-Key Infrastructure was  accepted at the flagship ACM Conference on Computer and Communications Security, CCS 2014. The paper proposes a new internet public-key  infrastructure that ensures that certificate-related operations, such  as certificate issuance, update, revocation, and validation are  transparent and accountable. ARPKI offers extremely strong security guarantees, where impersonation attacks are prevented unless attackers  manage to compromise multiple parties.

The paper Gaining Insight on Friendly Jamming in a Real-World IEEE  802.11 Network received the Best Student Paper Award at this year's  ACM Conference on Security and Privacy in Wireless and Mobile  Networks. The paper investigates the applicability of wireless signal  interference as a security primitive to enforce wireless access  control, i.e., jamming untrusted wireless packets, while minimising  the interference with legitimate wireless traffic. ACM WiSec is one of  the premier annual conferences in the field of wireless and mobile  security and privacy.
