True random bit generator based on cell phone recording and chaotic encryption

This paper proposes a design method of true random bit generator(TRBG) based on cell phone recording and chaotic encryption. Firstly a recording from cell phone is collected, then is transformed the format operated by MATLAB. The recording is turned into a sequence in computer by MATLAB, which is encrypted by chaotic sequence from a chaotic system. Finally, through binarization a true random bit sequence is produced. Randomness and security analysis is carried out. Simulation results show that the properties of the bit sequence are excellent in randomness and security, and the method is safe, fast and easy to realize.
