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