| Summary: | 碩士 === 佛光大學 === 資訊學系 === 101 === Access control system can be roughly divided into two categories: one is traditional, mainly based on different structures of locks with a key or a set of buttons (or a dial) for combinational codes to unlock; another type is digitally scientific, mainly based on digital electronic locks equipped with electromagnetic induction mechanism by means of applying a barcode card, RFID, fingerprint (palm print) identification system, or radio remote control to unlock.
Bluetooth is a radio LAN technology, which was first developed by Ericsson, then followed by IBM, Nokia, Toshiba and Intel. The primitive purpose was to replace IrDA and to increase the transmitting efficiency among the personal communicative devices in short distance. Due to the low cost of the products, small size of the modules and low energy-consumption, Bluetooth is convenient to be applied to various mobile devices. In addition, Bluetooth uses ISM (Industrial Scientific Medical) 2.4GHz radio network channel, which belongs to industrial, scientific and medical purposes, called ISM band and it is a global channel, so there is no need to apply for license and no dispute will be argued in any conditions. Android, based on Linux. It is a semi-open source operating system and is primarily applied on personal mobile devices. Currently, Google established the Open Handset Alliance (OHA) taking care of the maintenance and developing new systems. Linus is playing a major role on managing the system resources on Android platform, such as memory management, network service and driving operation on different hardware devices, all executed by Android.
This thesis tries to adopt the Frequency Hopping Spread Spectrum (FHSS) transmission function through the Bluetooth and multi-authenticated encryption technology, along with the open operating system of the smartphone --- Android, to establish a secure and reliable control system, to improve the weakness of the old style access control system, and to enhance the security on the management of access control system.
