Covert hopping communication method based on DNA encryption

Abstract

The invention provides a covert hopping communication method based on DNA encryption. The method comprises the following steps: a message server and a client are deployed; the client encrypts text contents into a letter A-P text sequence; the client carries out the DNA encryption on the text sequence with letter A-P ciphertext; the server configures four IP addresses which are respectively corresponding to four basic groups of DNA, and the client sequentially accesses the corresponding IPs on the server according to the encrypted DNA sequence for DNA encrypted sequence sending; when accessing the IPs on the server, the client calculates service port numbers based on time stamps, and makes access requests according to the target IPs and ports; the server obtains a letter A-P plaintext encrypted sequence through conversion according to rules; and the server recovers the original contents from the encrypted sequence. The method provided by the invention has the advantage that DOS attacks and eavesdropping attacks during communication can be effectively resisted.

Description

technical field [0001] The invention mainly relates to the field of covert communication of network security, in particular to a communication method based on DNA encryption and port jumping, so as to realize the security of communication in the network system. Background technique [0002] With the rapid development of Internet technology, people gradually acquire, transmit, process and utilize information through network technology. Especially in recent years, with the popularization of wireless networks and portable devices, networks have become closely related to people's lives. However, due to the openness and sharing of the network itself, network security incidents have increased year by year, and network information security is facing severe challenges. [0003] Traditional network threats mainly include Network Sniffing Attack, Denial of Service, replay, and Man-in-the-Middle (MIMT) attacks. In response to the above-mentioned network threats, people have adopted n...

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.
