However, this common data encryption communication method has the following problems: (1) No matter what encryption algorithm is used, it is facing the risk of brute force cracking, and the method of using a single key and a single encryption algorithm for all data in the entire communication process is still (2) Different network application requirements have different considerations for communication performance. The more complex the encryption algorithm is, the longer the encryption and decryption time will be. This is especially unsuitable for control transmission in industrial control and audio and video transmission in the monitoring field. Applications that are sensitive to real-time performance, and the high encryption and decryption time overhead will also reduce bandwidth utilization
However, this method of hiding a fixed location during key synchronization is easy to be guessed, and at the same time cannot avoid the risk of internal personnel leaking, which reduces the security of transmission

The invention discloses a data random encryption communication method combined with a Hamming code, which comprises the following steps that: a sender encrypts each user data packet delivered in a communication process by using a random encryption parameter, then performs minimum size filling and Hamming coding on the encrypted user data packet as required, places the current encryption parameter randomly in different bits of the coded data packet by taking the bit as a unit to form an error code bit, and sends the error code bit to a receiver to be analyzed and decrypted, so that the safety and the reliability of delivery of the user data packet are ensured. According to the invention, random position hiding is carried out on the random encryption parameter used in the delivery process of each data packet, so that the risk of exposure is reduced, and the security of a random encryption mechanism is enhanced. The method is particularly suitable for application occasions where the requirement for real-time performance is high, and random key encryption is carried out through a fast stream encryption algorithm to ensure safe communication (such as audio and video transmission).
Description
technical field [0001] The invention relates to the technical field of data encryption communication, in particular to a data random encryption communication method combined with Hamming codes. Background technique [0002] With the rapid development of computer network technology, data communication involves all aspects of network applications such as industrial control, Internet transmission, Internet of Things transmission and even cloud computing. In addition to the reliability of data communication, the first thing to consider is data security. Unauthorized access, illegal theft, and illegal tampering of data in the communication process will bring immeasurable losses to individuals, enterprises and society. Therefore, data encryption Technology was born. In the process of data communication, data will be transmitted in the form of frames or packets encapsulated into packets. In order to improve the security level of data transmission, a single key and a single encrypt...
