摘要:
为解决无线信道中的彩色图像通信安全问题,提出了一种基于微控制单元(micro controller units,MCU)的彩色图像实时加密通信方案. 利用所提密码系统提高混沌序列的随机性,通过基于混沌映射的伪随机数生成器(pseudo random number generator,PRNG)和XOR操作进行图像加密,并通过RS-232端口发送嵌入式加密系统的输出. 在PIC 16F873A微控制器上实施了提出的方案,并在无线链路上进行了实验. 结果表明,与其他优秀加密方法相比,所提方案提供了更高的安全性,可抵御各种已知攻击. 此外,使用双浮点精度的PRNG的处理速度为13.52 Mbit/s,能够满足现实应用的实时通信要求.
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.
