Abstract:
A digital interphone voice encryption scheme is proposed. Firstly, we designed a cryptosystem based on linear congruential generator and a hybrid chaotic system. The hybrid chaotic system with variable parameter is constructed based on Chebyshev map and Cubic map. And we ulitize linear congruential generator to provide the initial value for hybrid chaotic system. Then, a digital interphone voice cryptosystem is realized in STM 32 hardware platform. And all the steps described in the algorithm is implemented in STM 32. Finally, the experimental results show that the cryptosystem has higher security and better real-time performance.
