A Distributed Image Encryption/Decryption Method Based on Average Consistency

Abstract

The invention provides a distributed picture encryption / decryption method based on average consistency, which relates to the field of control and information technology. The present invention utilizes the characteristic of the average consistency of the algorithm to make each intelligent body approach the average value of the initial state. When an encrypted picture appears on the Internet, the computer where the picture appears is called an intelligent agent, and the intelligent agents through which the picture is circulated on the Internet will form a network with a specific structure. Assuming that these agents satisfy a certain topology, under the action of the distributed average consensus algorithm, the state values ​​of the agents that these photos flow through will be continuously updated, and the updated state value is the difference between the agent and its neighbors. Average value, after a period of time, the state value of the encrypted photo on each agent becomes the average value at the initial moment. This average value corresponds to the real value of the picture, thereby making the picture clear and achieving the purpose of decrypting the picture.

Description

technical field [0001] The invention relates to the field of control and information technology, in particular to a distributed picture encryption / decryption method based on average consistency. Background technique [0002] A multi-agent system is a collection of multiple coupled agents, each of which has a certain degree of autonomy and can communicate with other agents by perceiving the surrounding environment. There are clear advantages to using multi-agent system techniques in large systems. In recent years, the distributed cooperative control of multi-agent systems has become a hot spot in the field of control research, and the theoretical results have become more and more abundant. The main issues involved include consistency, coordination tracking, formation control, distributed optimization, distributed average tracking etc. Among them, the distributed average consensus algorithm has unique advantages in signal processing, and has attracted extensive research inte...

Problems solved by technology

[0003] The current image encryption / decryption algorithm is based on a single agent to process the image, the encryption / decryption steps are complicated, the calculation is large, and the robustness is poor

Especially when the number of images to be processed is extremely large, far exceeding the processing capacity of a single agent, it becomes very troublesome to use a centralized algorithm, and it may even result in the inability to realize the encryption / decryption of images within the specified time
