This application is applicable to the technical field of data connection, and provides a method, apparatus, terminal device and storage medium for establishing a data connection, wherein the method includes receiving a first certificate chain sent by a server; the first certificate chain includes first verification information ; Obtain the pre-stored second certificate chain, and verify the first authorization certificate according to the second certificate chain; After the first verification information is verified, receive the target validity period information sent by the server; Obtain the first authorization certificate in the second authorization certificate Second validity period information; according to the second validity period information, establish a data transmission channel with the server after verifying that the target validity period information is legal. The first authorization certificate is preliminarily verified by pre-storing a complete second certificate chain in the terminal device, and after the verification is passed, the second verification is performed on the target validity period information issued by the server, so as to improve whether the verification server is legal or not. reliability to further ensure the reliability of data transmission.
Description
technical field [0001] The present application belongs to the technical field of data connection, and in particular, relates to a method, apparatus, terminal device and storage medium for establishing a data connection. Background technique [0002] In the prior art, a Secure Socket Layer (SSL) certificate is widely used in network communication. When a session connection is established between the terminal device and the server, the server will issue its authorization certificate to the terminal device, and the terminal device will automatically verify the validity of the authorization certificate according to the stored root certificate to ensure the authenticity of the server. However, the validity period of the root certificate is too long, and the certificate authority cannot verify the latest information of the website on the server side in time, and cannot ensure the security of the website in time. SUMMARY OF THE INVENTION [0003] The embodiments of the present a...
