Abstract:This paper is focused on the area of physical access control systems (PACs), particularly on the systems forbuilding access control. We show how the application of modern cryptographic protocols, namely the cryptographicproofs of knowledge, can improve the security and privacy protection in practical access controlsystems. We propose a novel scheme SPAC (Secure Physical Access Control) based on modern cryptographicprimitives. By employing the proofs of knowledge, the authentication process gets more secure and privacyfriendly in comparison to existing schemes without negative influence on the implementation complexity orsystem performance. In this paper, we describe the weaknesses of existing schemes, show the full cryptographicspecification of the novel SPAC scheme including its security proofs and provide benchmarks onoff-the-shelf devices used in real commercial systems. Furthermore we show, that the transition from an oldinsecure system to strong authentication can be easy and cost-effective.(More)
