Implementation Of Bluetooth Authentication Algorithm Based On RNS

Bluetooth is a global standard of data and audio communication through wireless transfer. It is attracted more and more attention as a new technique. Bluetooth technology has made rapidly progress in recent years.Bluetooth is designed as a wireless cable replacement to connect a wide range of devices. It is provided a short range, peer-to-peer wireless communications between two units. It's important to avoid the data been attacked or stolen the same time we ensure the data is transferred correctly.The principle of SAFER series algorithm is introduced in paper, as well as RNS(Residue Number System). Based on RNS ,the core algorithm of subkeys production and the diffusion layer establishment will make the improvement. Understanding this improvement algorithm, it carries on the diffusibility analysis and the many kinds of cryptanalysis. Compared with the original authentication algorithm,it will obtain the feasibility of algorithm improvement. Finally it compile the realization procedure, and has realized the bluetooth subkey production and software simulation in this foundation. Meanwhile it describes this algorithm function module, and carries on the time-simulation realization by Altera Corporation simulation.
