Abstract：Through analysis on the internal structure and the working characteristic of Bluetooth chip, a parallel cryptography algorithm instruction structure model based on Digtal Signal Processor (DSP) coprocessor and the algorithm working procedure was designed. The model was designed by considering two aspects of time overhead and storage space. And the model implemented the high computational and complex cryptography algorithm with DSP coprocessor possible during the Bluetooth communication. The experimental results show that the method can reduce the influence of complex cryptography to Bluetooth transmission.
