[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. It is understood that the specific embodiments described herein are only used to explain the related applications, rather than to limit the applications. It should also be noted that, for ease of description, only the parts related to the related applications are shown in the drawings.

[0038] With the rapid development of mobile Internet in recent years, more and more terminal devices need to connect to the Internet through cellular networks, which requires that each connected device needs to deploy the operator's SIM card. The increasing application scenarios have led to a frequent increase in the number of applications deployed on SIM cards. The increase in applications requires the SIM card operating system to have richer functional interfaces. At the same time, it may also require the root keys of new applications to be pre-set in COS to support the use of new applications.

[0039] However, the current SIM card key presetting method has the following problems: (1) Every time the SIM card COS needs to be upgraded, the card manufacturer produces a new SIM card. At the same time, on the card manufacturer's production line, the key is generated in a decentralized manner through an encryption machine and then written into the card through a device; (2) For SIM cards that have already been issued, COS does not provide a method to re-write the key, so there are limitations on application expansion.

[0040] In order to solve the problem that there is no method for re-writing the key for the COS in the issued SIM card, resulting in limitations in application expansion, the embodiments of the present application provide a key writing method, device, equipment, storage medium and computer program product. After receiving the update results sent by one or more SIM card chips, the first platform sends a first request to the second platform; wherein the update result is used to indicate whether the COS in the SIM card chip is updated successfully, the first request carries one or more of the identification information of the SIM card chip, the identification information of the card application in the SIM card chip and the key version information, and the second platform is at least used to generate the key information corresponding to the card application; receive the first response message sent by the second platform; wherein the first response message at least includes the encrypted key information; send the encrypted key information to the corresponding SIM card chip, so that the SIM card chip writes the decrypted key information into the corresponding card application through the updated COS; the second platform generates the key information corresponding to the card application based on the identification information of the SIM card chip, the identification information of the card application in the SIM card chip and the key version information; and send the first response message to the first platform. It can be seen that after receiving the update results sent by one or more SIM card chips, the first platform can send a first request to the second platform, which carries one or more of the identification information of the SIM card chip, the identification information of the card application in the SIM card chip, and the key version information, so that the second platform can generate the key information corresponding to the card application based on the identification information of the SIM card chip, the identification information of the card application in the SIM card chip, and the key version information, and then send the encrypted key information to the first platform, so that the first platform sends the encrypted key information to the corresponding SIM card chip, and the SIM card chip can write the decrypted key information into the corresponding card application through the updated COS, that is, the embodiment of the present application supports the COS in the issued SIM to write the new key of the card application, thereby completing the pre-setting of the new key, thereby expanding the application usage scenarios in the SIM card.
