Communication authentication method, subscription verification method, and communication method

Abstract

The present invention discloses a communication authentication method, a subscription verification method, and a communication method, which are applied to a communication module. The communication module is communicatively connected to an eSIM card and a communication network. The authentication method includes: verifying whether a subscription authentication operation is completed; in the case of determining that the subscription authentication operation is completed, sending a first authentication request instruction to the eSIM card; obtaining an authentication feedback instruction corresponding to the first authentication request instruction; and generating a corresponding communication authentication result based on the authentication feedback instruction. By adopting two-way identity authentication using information derived from key information for identity legitimacy identification, the authentication reliability and authentication effectiveness in the communication authentication process are effectively improved, and the network communication security is enhanced.
