A Jump Covert Communication Method Based on DNA Encryption

Abstract

The invention provides a DNA encryption-based hopping concealment communication method, comprising the following steps: deploying a message server and a client; the client encrypts the text content into a text sequence of letters A-P; The text sequence of ‑P is encrypted by DNA; the server is configured with four IP addresses corresponding to the four bases of DNA, and the client accesses the corresponding IP of the server according to the encrypted DNA sequence to send the DNA encrypted sequence; When accessing the IP of the server, the service port number is calculated based on the timestamp, and then the access request is made through the destination IP and port; the server side converts it into a plaintext encrypted sequence of letters A-P according to the rules; the server restores the encrypted sequence to the original content. The invention can effectively defend against DOS attacks and eavesdropping attacks in the communication process.

Description

technical field [0001] The invention mainly relates to the hidden communication field of network security, in particular to a communication method based on DNA encryption and port hopping, which realizes the security of communication in a network system. Background technique [0002] With the rapid development of Internet technology, people gradually acquire, transmit, process and utilize information through network technology. Especially with the popularity of wireless networks and portable devices in recent years, the network has been closely related to people's lives. However, due to the openness and sharing of the network itself, network security incidents are increasing year by year, and network information security is facing severe challenges. [0003] Traditional network threats mainly include network sniffing attacks, denial of service (Denial of Service), replay and man-in-the-middle (MIMT) attacks. In response to the above-mentioned network threats, people have a...

Problems solved by technology

In addition, since the interception of messages in the communication process is difficult to be discovered by both parties in the communication, this makes it difficult to transmit more important messages in port hopping communication.
