Embodiment 1

[0069] This embodiment provides a method for creating an auxiliary security domain, which is applied to the SM-SR (Subscription Manager Security Routing) network element of the subscription relationship management platform, such as figure 1 As shown, the method includes:

[0070] Step S102: Receive a request for creating a supplementary security domain SSD (Supplementary Security Domain) sent by the service platform.

[0071] It should be noted that the present invention is based on a standard eUICC architecture and an eUICC card, and creates SSDs required for services in the currently activated profile. The eUICC architecture mainly includes SM-SR, SM-DP (SubscriptionManager Data Preparation, contract relationship Management platform data preparation), ECASD, ISD-P and ISD-R, the complete eUICC architecture can also include other network elements, which is not limited.

[0072] In this embodiment, the SM-SR is an important network element of the remote management platform of...

Embodiment 2

[0134] refer to image 3 , this embodiment provides a method for creating an auxiliary security domain, which is applied to the eUICC, and the method includes:

[0135] Step S202: The ISD-R of the eUICC receives the SSD creation command sent by the SM-SR, and the SSD creation command is sent by the SM-SR after receiving the SSD creation request sent by the service platform;

[0136] Step S204: The ISD-R creates an SSD in the eUICC according to the SSD creation command;

[0137] Step S206: If the SSD creation success message sent by the created SSD is received, the ISD-R returns an SSD creation response to the SM-SR, so that the SM-SR generates an initial key for the created SSD after receiving the SSD creation response, and sends the The service platform sends the initial key;

[0138] Step S208: ISD-R receives the initial key sent by SM-SR, and sends the initial key to the created SSD;

[0139] Step S210: The created SSD receives the initial key, and uses the initial key t...

Embodiment 3

[0146] This embodiment provides a method for creating an auxiliary security domain, which is applied to SM-DP, and the method includes:

[0147] Receive the request for applying for SSD migration token sent by SM-SR;

[0148] Generate an SSD migration token according to the request for applying for an SSD migration token;

[0149] Returning the SSD migration token to the SM-SR, the SSD migration token is used to trigger the SM-SR to send an SSD migration command carrying the SSD migration token to the ISD-R, so that the ISD -R forwards the SSD migration command to the Profile security domain ISD-P, and makes the ISD-P verify the SSD migration token after receiving the SSD migration command, and sends the SSD migration token to the The eUICC sends indication information authorizing the eUICC to migrate the created SSD to the ISD-P, so that the eUICC migrates the created SSD to the ISD-P.

[0150] Optionally, the request for applying for an SSD migration token carries an EID; ...

Abstract

The invention provides an auxiliary security domain creation method, an SM-SR and a system. The method comprises the following steps: receiving an auxiliary security domain SSD creation request sent by a service platform; sending an SSD creation command to a root security domain ISD-R of the eUICC according to the SSD creation request, so that the ISD-R creates an SSD in the eUICC after receiving the SSD creation command; receiving an SSD creation response returned by the ISD-R, and generating an initial key for the created SSD according to the SSD creation response; sending the initial secret key to the ISD-R, so that the ISD-R forwards the initial secret key to the established SSD; and sending the initial key to the service platform, so that the service platform uses the initial key to establish a secure channel with the established SSD. According to the method, the SM-SR and the system, the problem that a terminal cannot support coexistence of applications of multiple service providers on an eUICC due to the fact that the applications of the service providers do not have an exclusive security domain on a terminal side in related technologies can be solved.

Description

technical field [0001] The invention relates to the technical field of smart cards, in particular to a method for creating an auxiliary security domain, an SM-SR and a system. Background technique [0002] eUICC (Embedded Universal Integrated Circuit Card, Embedded Universal Integrated Circuit Card) is a new telecom smart card technology that supports remote configuration and can be used in any form of SIM card, including embedded and pluggable SIM cards. The eUICC card can support flexible network replacement through remote configuration in the air, ensuring the highest speed network support for devices, improving the security and work efficiency of devices, and enabling connected devices to expand from the public market to a richer Internet of Things and consumer products Market, can be widely used in smart grid, Internet of Vehicles, security monitoring and other fields. [0003] However, in the face of this new type of card architecture, it is necessary to consider how ...
