基于混沌序列的无线网络加密传输方法研究

Research on Wireless Network Encryption Transmission Method Based on Chaotic Sequence

无线网络由于具有开放性,使得图像信息在传输过程中存在安全风险,为此笔者提出一种基于混沌序列的无线网络加密传输方法。该方法首先会加密发送通过混沌系统生成混沌序列,然后对明文图像进行加密,包括置乱和扩散,并向接收端发送加密图像,接收端接收密文图像后会进行解密。实验结果表明:与传统加密传输方法相比,所研究方法的信息熵更大,相关性系数更靠近0,由此证明所研究方法的性能更好,更能保证图像信息安全。

Due to the openness of wireless networks, there are security risks in the transmission of image information. For this reason, the author proposes a wireless network encryption transmission method based on chaotic sequences. This method first encrypts and sends the chaotic sequence generated by the chaotic system, then encrypts the plaintext image, including scrambling and diffusion, and sends the encrypted image to the receiving end, and the receiving end will decrypt the ciphertext image after receiving the ciphertext image. The experimental results show that: compared with the traditional encryption transmission method, the information entropy of the research method is larger and the correlation coefficient is closer to 0, which proves that the performance of the research method is better and can guarantee the security of image information.
