The Bluetooth security mechanism and the structure of the Bluetooth chip are analyzed, and then a Bluetooth security transmission scheme is proposed in this paper. By redistributing the in-chip resources, DSP coprocessor is used to deal with the comparative complex cryptographic algorithm. Contrasting with adding extra chip hardware, the proposed scheme solves the problem of information leakage and hardware complexity. Experimental results demonstrate that the scheme can not only enhance the communication security of Bluetooth and reduce the cost of Bluetooth security products, but also shows high reliability without influencing the Bluetooth transmission speed.
