In recent years,with the comprehensive popularization of the Internet,citizens have put forward new and higher requirements for information security and privacy protection.In order to keep the information secure,we are based on the requirements of"winning the net-work war in the new era"and carry out in-depth research on the research and realization of image encryption algorithms.We propose an image encryption technology based on the China secret SM2 digital envelopes and DNA encoding,combining image encoding technology,pub-lic key technology,and password protection technology.In this algorithm,the focus is on re-alizing the complexity of the key space,robustness,randomness,and low correlation of the image using Python.The histogram of the image is analyzed,and the research results have enhanced encryption security while achieving the replacement of public key by Chinese algo-rithm.
