Toward More Secure and Reliable Access Control
Roel Peeters, Dave Singelée, Bart Preneel · IEEE Pervasive Computing · 2011
Conventional access control mechanisms, relying on a single security token to authenticate remote users, introduce a single point of failure and are vulnerable to relay attacks. A threshold-based distance-bounding protocol that distributes a user's private key among various personal devices improves system security and reliability.
