This paper proposes an NFC-based, off-line door access control mechanism. The credentials to access the door services, such as opening its lock, are first obtained by users from a central authentication server. Those credentials are time bounded, i.e., they can only be used on a specific time frame. In our case, we used daily credentials, but other time intervals could have been used. Door locks keep a record of all successful opening requests, which can be collected using another door service, also available through its NFC interface. The access credentials are fetched and used, within a challenge-response authentication protocol, by an application running on an NFC-enabled device, such as a smartphone. For a proof of concept we implemented a prototype of our system with an Arduino with an NFC shield, for controlling a door lock, an Android Nexus 7 mobile device and a Web server for providing daily access credentials.
