Embodiment Construction

[0034] First of all, some nouns involved in the embodiments of this application are explained:

[0035] 1. eSIM and eUICC

[0036] The eSIM card is to embed the traditional SIM card directly on the device chip, instead of adding it to the device as an independent removable part, and the user does not need to insert a physical SIM card. The eSIM card will allow users to choose operator packages more flexibly, or change operators at any time without unlocking the device or purchasing a new device. Embedded Universal Integrated Circuit Card (eUICC), eUICC is the physical form of eSIM card.

[0037] 2. Digital certificate

[0038] Such as figure 1 As shown, digital certificates include: CI root certificate (level 1 certificate), EUM certificate (level 2 certificate), SM-SR certificate (level 2 certificate), eUICC certificate (level 3 certificate). The CI root certificate is issued by a certificate authority (Certificate Authority, CA), the EUM certificate, SM-SR certificate an...

Abstract

The embodiment of the present application discloses a routing method and a device, which relate to the field of communication technology and solve the problem that the eSIM card in the prior art doesnot support the switching of the management rights of multiple operators and cannot solve the conversion problem of the international operators. The specific scheme is as follows: the first routing platform receives the eUICC information set of the embedded card sent by the second routing platform; The first routing platform and the second routing platform are routing platforms of different operators; the validity of the eUICC certificate is verified; if the first routing platform determines that the eUICC certificate of the eUICC is valid, the first routing platform transfers the SM-SR certificate to the second routing platform; a first random number transmitted through the second routing platform by the eUICC is received; the first routing platform and the eUICC negotiate a key; if thefirst routing platform and the eUICC succeed in negotiating the key, the first routing platform and the eUICC communicate directly.

Description

technical field [0001] The embodiments of the present application relate to the technical field of communications, and in particular, to a routing method and device. Background technique [0002] At present, China has become a country on the wheels of automobiles, and is facing the improvement of transportation efficiency brought about by the Internet. The emergence of Internet of Vehicles can lead the development of intelligent transportation. exchange of information. [0003] The communication requirements of the Internet of Vehicles are actually security requirements. Traditional plug-in cards cannot ensure the normal use of communication services after a collision. Compared with traditional plug-in cards, embedded SIM cards (Embedded-SIM, eSIM) Security is more secure. In the prior art, the eSIM card installed on the car is a hard-coded number card produced after consultation with the operators of various countries in advance. However, since the car is to be exported t...
