Embodiment Construction

[0087] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0088] In the current technology, the terminal device is returned to the factory to rewrite the expired eUICC certificate. This method undoubtedly brings the problem of cumbersome operation and high cost. Therefore, it brings a lot of inconvenience to users. The certificate rewriting method, device, storage medium, equipment, and system provided in the embodiment of the application rea...

Abstract

The invention provides a certificate rewriting method and device, a storage medium, equipment and a system. The method comprises sending a verification request to a certificate management platform; receiving a verification request response sent by the certificate management platform, sending an eUICC certificate rewriting request to a certificate management platform, and receiving an eUICC certificate rewriting request response sent by the certificate management platform, wherein the eUICC certificate rewriting request response comprises a transaction serial number, a rewritten eUICC certificate and a ciphertext of a second private key; decrypting the ciphertext of the second private key; and obtaining a second private key, storing the rewritten eUICC certificate and the second private key, and signing the transaction sequence number by using the second private key to obtain a rewritten eUICC certificate signature file, thereby realizing online rewriting of the eUICC certificate, reducing the maintenance cost of the eUICC, and further improving the user experience.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a certificate rewriting method, device, storage medium, equipment and system. Background technique [0002] Embedded subscriber identity module (eSIM) card, also known as virtual smart card, differs from traditional SIM card in that: (1) The hardware part of traditional SIM card is used as a dedicated security chip (that is, embedded universal integrated The circuit card (embedded universal integrated circuit card, eUICC)) is directly embedded in the terminal device, instead of being added to the terminal device as an independent removable part, and does not require a special card slot in the terminal device. Therefore, no user Insert a physical SIM card into the terminal device; (2) load the user's subscription data (i.e. eSIM electronic card) in the operator's network into the security chip through over-the-air download, so that a built-in chip can be used ...
