Firstly, the drive-response chaotic model of laser mass data communication transmission is constructed and the key scheme of digital certificate of laser mass data communication is designed. The public key of public key is configured with certificate-based hash chaotic encryption system to calculate the public key of corresponding digital certificate Symbol frequency, digital certificate encryption design. Finally, the experimental analysis shows that the proposed method performs digital certificate encryption for laser mass data communication, has better anti-attack performance and less entropy leakage, indicating that the proposed encryption technology has better encryption performance.
