Embodiment 1

[0037] Embodiment 1 of the present invention proposes a virtual SIM card parameter management method. Such as figure 1 As shown, the method includes the steps of:

[0038] S1. The mobile terminal encrypts the authorization request and sends it to the network side, so that the network side assigns the encrypted SIM card parameters to the mobile terminal according to the encrypted authorization request.

[0039] In Embodiment 1 of the present invention, the encryption algorithm and the encryption key are preset and stored in the network side and the mobile terminal, and the encryption algorithm and the encryption key can be selected according to needs, one of which is as follows: the mobile terminal pre-stores the SIM card The private key and the public key on the network side. The public key of the SIM card and the private key on the network side are pre-stored on the network side. When the mobile terminal needs the network side to allocate SIM card parameters, a certain term...

Embodiment 2

[0046] Embodiment 2 of the present invention proposes a virtual SIM card parameter management device. Such as figure 2 As shown, the device includes:

[0047] The encryption module 10 is used to encrypt the authorization request and send it to the network side, for the network side to distribute encrypted SIM card parameters for the mobile terminal according to the encrypted authorization request;

[0048] A receiving module 20, configured to receive the SIM card parameters allocated by the network side;

[0049] Decryption module 30, for decrypting the SIM card parameters;

[0050] The updating module 40 is configured to update the local SIM card parameters according to the decrypted SIM card parameters.

[0051] Such as image 3 As shown, the encryption module 10 includes:

[0052]The first encryption unit 11 is used to encrypt the preset terminal identification through the prestored SIM card private key;

[0053] The second encryption unit 12 is configured to re-encr...

Abstract

The invention is suitable for the communication field and provides a virtual SIM card parameter management method and device. The method comprises following steps: a mobile terminal encrypts an authorization request and sends to a network side, so that the network side can distribute an encrypted SIM card parameter for the mobile terminal according to the encrypted authorization request; the SIM card parameter distributed by the network side is received; the SIM card parameter is decrypted; and an SIM card parameter of the home terminal is updated according to the decrypted SIM card parameter. By means of the virtual SIM card parameter management method and device provided by the invention, the security problem of the virtual SIM card parameters is solved.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to a virtual SIM card parameter management method and device. Background technique [0002] With the development of Internet of Things technology, Internet of Things network security has also been put on the agenda. Like traditional IT networks, Internet of Things mainly focuses on access control, privacy protection, user authentication, non-repudiation, data confidentiality, communication Layer security, data integrity and other security categories. However, the objects connected and processed by the Internet of Things are mainly machines or objects and their related large amounts of data. The "ownership" characteristics of these processed objects make the Internet of Things have higher requirements for data security than the Internet that mainly processes "text" information. , the information that needs to be protected includes the business data transmitted and processed in ...
