Covert communication method, device and system, computer and readable storage medium

Abstract

The invention relates to a covert communication method, a device and a system, a computer and a readable storage medium, and the method comprises the steps: receiving a data reading program transmitted by a control end; acquiring local target data by running the data reading program, converting the target data into a data packet according to a preset coding rule, and sending the data packet to the control end, so that the control end receives the data packet and analyzes the data packet according to the coding rule to obtain the target data; wherein the data in the data packet is communicable data identified by a security protection device in the host. According to the method, the data reading program is received, the target data is obtained according to the data reading program, the target data is converted into the data packet which cannot be intercepted by the security protection equipment according to the preset coding rule, and the data packet is sent to the control end, so that the control end can analyze the data packet according to the coding rule; and receiving and acquiring the target data in a hidden manner are realized.

Description

technical field [0001] The present application relates to the computer field, in particular to a covert communication method, device, system, computer and readable storage medium. Background technique [0002] Based on security considerations, security protection devices such as firewalls are usually installed in the host. During the network communication data interaction between the host and other clients, the security protection devices usually detect the target data to prevent data from being stolen and attacked. [0003] However, in order to ensure social security, the relevant professional departments have the need to intercept the target data to conduct security analysis on the target data. At present, when the professional department acquires the target data in the host, the transmission behavior from the inside to the outside is easily detected and intercepted by the security protection equipment, which makes the professional department unable to obtain the target da...

AI Technical Summary

Problems solved by technology

[0004] The embodiment of the present application provides a covert communication method, device, system, computer, and readable storage medium to at least solve the problem of the internal-to-outward transmission when the professional department needs to obtain the data of the target in the related art. It was discovered and intercepted by the security protection equipment, which made it impossible for the professional department to successfully obtain the target data
