Abstract:
In order to solve the security problem of color image communication in wireless channel,a real-time encryption and communication scheme for color images based on micro controller units(MCU)is proposed. The proposed cryptographic system is used to improve the randomness of the chaotic sequence,the image is encrypted through a pseudo-random number generator(PRNG)based on chaotic mapping and XOR operation,and the output of the embedded encryption system is sent through the RS-232 port. The proposed scheme was implemented on the PIC 16F873A microcontroller,and experiments were carried out on the wireless link. The results show that the proposed encryption scheme provides a high degree of security,can resist various known attacks,and has better security performance than classic encryption algorithms. In addition,the processing speed of the proposed PRNG with double floating point precision is 13.52 Mbit/s,which can meet the real-time communication requirements of practical applications.
