Distributed picture 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 technical field of control and information. According to the distributed picture encryption / decryption method, the average consistency characteristic of the algorithm is utilized, so that each agent approaches the average value of the initial state. When an encrypted pictureappears on the internet, a computer where the picture appears is called as an agent, and the agent through which the picture flows on the internet forms a network with a specific structure. Supposingthat the agents meet a certain topological structure, under the action of a distributed average consistency algorithm, state values of the agents through which the picture flows are continuously updated, the updated state values are an average value of the agents and neighbors of the agents, after a period of time, a state value of the encrypted picture on each agent is changed into the average value at the initial moment, and the average value corresponds to a true value of the picture, so that the picture becomes clear, and the purpose of decrypting the picture is achieved.

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
