In this embodiment, the Profile downloading method is applied to a mobile terminal, which may be the mobile terminal shown in fig. 1. The Profile management platform comprises a Profile generation server and a Profile download server, wherein the Profile generation server is used for generating Profile data, encrypting the Profile data and transmitting the encrypted Profile data to the Profile download server, and the Profile download server is used for storing the Profile data and managing Profile download. In specific implementation, in order to ensure the safety of the Profile, the Profile needs to be encrypted, a specific encryption mode is that the Profile generation server generates a Profile plaintext, the Profile plaintext is transmitted to an encryption machine, a key is randomly generated in the encryption machine, the Profile is encrypted by using the key to obtain a Profile ciphertext, the randomly generated key is encrypted by using the transmission key to obtain a key ciphertext, and finally the Profile ciphertext and the key ciphertext are transmitted to a Profile download server.
Before downloading the Profile, the download initialization operation that needs to be executed includes network operator subscription, Profile download preparation, and Profile download information, that is, a user sends relevant information required by the subscription, such as Electronic IDentity (EID), International Mobile Equipment IDentity (IMEI), and IDentity card information, to a corresponding network operator to execute a subscription operation, such as a Mobile operator, a unicom operator, or a telecom operator, through a subscription channel provided by the network operator, and after the subscription is completed, the network operator notifies a Profile download server to prepare a corresponding Profile, and notifies the Profile download information, such as Profile download credentials and addresses, to the user. The method comprises the steps that a mobile terminal receives Profile download information input by a user through an information input interface, namely a Profile download certificate and an address, at the moment, the mobile terminal requests identity authentication information of an eSIM card from eSIM card equipment, namely, an identity authentication information acquisition instruction is triggered, the identity authentication information acquisition instruction is sent to the eSIM card equipment, the eSIM card equipment receives the identity authentication information acquisition instruction, the eSIM card equipment acquires identity authentication information from the eSIM card according to the identity authentication information acquisition instruction, and the identity authentication information is returned to the mobile terminal. The identity authentication information includes, but is not limited to, EID, IMEI, and eUICC certificate.
After the identity authentication information is acquired, verifying the identity authentication information, namely executing a preset verification process on the identity authentication information, and after the execution of the preset verification process is finished, determining whether the identity authentication information passes verification, specifically, firstly, sending the identity authentication information to a Profile download server, verifying the identity authentication information by the Profile download server, signing the identity authentication information after the verification passes, then, returning the signed identity authentication information to a mobile terminal, forwarding the signed identity authentication information to an eSIM card device by the mobile terminal, verifying the signed identity authentication information again by the eSIM card device, and after the signed identity authentication information passes verification, signing the signed identity authentication information again by the eSIM card device, namely, carrying two signatures in the identity authentication information, wherein the two signatures are respectively carried out by the Profile download server and the eSIM card device, after the execution of the preset verification process is completed, whether the identity authentication information passes the verification is determined, that is, whether the identity authentication information passing the preset verification process carries two different signatures, wherein the two signatures are the preset signatures, and if the identity authentication information passing the preset verification process carries two different signatures, and the two signatures are the preset signatures, the identity authentication information is determined to pass the verification.
Step S102, if the identity authentication information passes the verification, when a Profile download confirmation instruction is monitored, sending the Profile download information and the identity authentication information to a Profile download server;
in this embodiment, the mobile terminal is connected to the Profile download server through the network, if the identity authentication information passes verification, the mobile terminal displays a Profile download confirmation bullet frame, where the Profile download confirmation bullet frame includes a confirmation control and a cancellation control, when it is detected that the confirmation control is touched, a Profile download confirmation instruction is triggered, when it is detected that the cancellation control is touched, Profile download is suspended, when it is detected that the Profile download confirmation instruction is touched, Profile download information and identity authentication information are sent to the Profile download server, the Profile download server obtains a Profile download certificate and a Profile download address from the Profile download information, and queries a corresponding Profile database through the Profile download certificate and the Profile download address, then obtains Profile data corresponding to the identity authentication information from the Profile database, and sends the Profile data to the mobile terminal.
Step S103, receiving the Profile data returned by the Profile download server, and sending the Profile data to the eSIM card device, so that the eSIM card device writes the Profile data into the eSIM card.
