Safe communication method, device, computer device and storage medium

Abstract

The invention relates to a safe communication method, device, computer device and storage medium. The method includes acquiring a receiving terminal mark; inquiring a self-signed first root certificate generated by a receiving terminal; performing encryption on the communication data through the first root certificate; sending the encrypted communication data to the receiving terminal so as to enable the receiving terminal to decrypt the communication data through a first private key, wherein the first private key is corresponding to the first root certificate. According to the invention, through sending a self-signed root certificate to an opposite party in communication, i.e., sending the self-signed root certificate to the sending terminal from the receiving terminal, the sending terminal can sign the communication data according to the self-signed root certificate of the receiving terminal. In this way, only the terminal having the corresponding private key, namely, the receiving terminal, can acquire the plaintext of the communication data, so that a communication server can be prevented from acquiring the plaintext of the communication data, and the safety of the private keyis ensured and the safety of the communication data is improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a secure communication method, device, computer equipment and storage medium. Background technique [0002] Usually, the security in the communication process is jointly guaranteed by the communication server and the communication parties, that is, the communication server can see the communication content of the communication parties, so that the communication server can obtain the communication content, which will lead to the leakage of the communication content. [0003] Traditionally, in order to avoid this situation, the communication client applies to the authoritative certificate provider CA to issue a certificate, and uses the issued certificate to ensure the dual communication, that is, the information security between the sending end and the receiving end. However, in this case, information security completely depends on the certificate provider. Once the cert...
