A data communication and storage method

Abstract

A data communication and storage method, comprising the following steps: (1) constructing a communication system including a control center, an interactive terminal, and an interactive medium, where the interactive terminal can write data to the interactive medium and can read data from the interactive medium (2) establish a secure communication channel, bidirectionally connect the interactive terminal and the control center, and the control center processes and controls the data of the interactive terminal entering the system; (3) the control center completes the security verification of the interactive terminal through the secure communication channel, If the interactive terminal is not safe, prevent the data of the interactive terminal from entering the system, and if the interactive terminal is safe, allow the data of the interactive terminal to enter the system; (4) store the data of the interactive terminal entering the system. This method can establish a secure communication channel more quickly, increases the difficulty of cracking digital certificates, and can enhance the security and reliability of the data communication process. At the same time, this method has good compatibility and read-write efficiency in the data storage process. .

Description

Technical field [0001] The invention relates to the technical field of data processing, in particular to a data communication and storage method. Background technique [0002] With the rapid development of communication technology, the functions of user terminals are becoming more and more diverse, and more and more user private information is stored in user terminals. In order to ensure the security of user data stored in user terminals, it is necessary to Stored user data is encrypted. Nowadays, with the development of the information age, the security of information interaction has attracted more and more attention. At present, some encryption measures are adopted in various data exchanges, mainly using some digital encryption methods. [0003] A digital certificate is a kind of electronic identity proof. Usually, a digital certificate is an invariable encrypted data. The passwords, passwords and digital certificates we use seldom use plaintext data for security. They a...

Problems solved by technology

[0005] However, there is still a large risk of leakage in this communication method, because no dynamic data participates in the encryption operation, so the encrypted result will not change. How complicated the encryption process is, once the source code is leaked, it is hard to escape the fate of being cracked on a large scale. The reason is very simple. After mastering the source code, the password cracker can use the input password to obtain the encryption result, and the website needs to face a large number of terminals. , the same communication protocol must be adopted for all terminals, otherwise, it is possible that terminal A can pass the verification
