  • Abstract Physical keys are a basic part of everybody's daily life. It is a proved system and has been subjected to continuous improvements, including access cards and door readers of fingerprint. However, existing physical access control systems are not that easy to control. The distribution and the invalidation of access cards are complicated, time consuming and not very convenient. Loosing an access card can occur without quickly noticed. For organizations where access to many different private buildings, each with its own lock and key, the circulation of keys to the right person at the right time is a complex and costly process. Furthermore, carrying a large number of keys is not practical and the possibility of keys getting stolen or lost increases.
    Our goal is to propose a mobile phone based access control system and design a solution that can replace physical keys for accessing private buildings. We propose a solution using digital keys on Bluetooth-enabled mobile phones providing manual and automatic unlocking. The design allows easy distribution of keys to users, with access control imposed by easily installable autonomous lock devices.
    This system supports fine-filtered access rights, remote distribution, and decentralized administration of access rights and revocation. Additionally, the system manages access to remotely located locks with low power supply and temporary communication abilities. We present a solution for fully automatic discovery and connection establishment using Bluetooth. Moreover we present a simple and secure authentication and access control protocol, allowing each mobile phone to unlock multiple different locks using a single identity certificate and public unencrypted digital keys. We build a prototype application, measure the exact energy consumption and time usage of the application. In addition to all obvious advantages of this system, it is at least as secure as all existing physical access control solutions。
