Embodiment 1

[0032] In order to solve the problem existing in the prior art that certificate authentication cannot be realized if the server does not store a certificate issued by the same CA center corresponding to the smart card, a certificate authentication method is provided in the embodiment of this application. see figure 1 as shown, figure 1 It is a schematic flowchart of the certificate authentication method provided in the embodiment of this application, including:

[0033] S101: Receive a certificate to be authenticated of the smart card.

[0034] It should be noted that, before implementing the solutions provided by the embodiments of the present application, the present application needs to build a trusted environment among CA centers in advance.

[0035] The so-called trusted environment is to build an environment in which CA centers trust each other and each CA center with high security and trustworthiness can be connected to each other through a network.

[0036] In the e...

Embodiment 2

[0080] In this embodiment, on the basis of Embodiment 1, a specific code number data download process in which the smart card is an eSIM card is taken as an example to further illustrate this application. Wherein, the eSIM card is set on the terminal, and the terminal realizes the connection with the server (code number server in this embodiment, which provides certificate authentication and code number download service) through LPA (LocalProfile Assistant, local configuration assistant).

[0081] see Figure 4 As shown, the whole process includes:

[0082] 1. LPA sends an information acquisition instruction to the eSIM card, requesting to obtain the eID of the eSIM card, the manufacturer certificate CERT_EUM, and the eSIM card certificate CERT_EUICC.

[0083] 2. The eSIM card returns its own eID, manufacturer certificate CERT_EUM, and eSIM card certificate CERT_EUICC to the LPA.

[0084] 3. The LPA sends a code number download request to the code number server, and the code...

Embodiment 3

[0103] Based on the same inventive concept, the embodiment of the present application also provides a certificate authentication device 500 and a code number downloading device 600 . see Figure 5 and Figure 6 as shown, Figure 5 shows the use of figure 1 The method shown in the certificate authentication means, Figure 6 shows the use of image 3 The code number downloading device of the method shown. It should be understood that for the specific functions of the device 500 and the device 600, reference may be made to the above description, and to avoid repetition, the detailed description is appropriately omitted here. The device 500 and the device 600 include at least one software function module that can be stored in a memory in the form of software or firmware or solidified in the operating system of the device 500 and the device 600 . specifically:

[0104] see Figure 5 As shown, the apparatus 500 is applied to the server, and includes: a receiving module 501 ,...

Abstract

The invention provides a certificate authentication method and device, a code number downloading method and device, a server and a storage medium. The method comprises the following steps: receiving a to-be-authenticated certificate of an intelligent card by a server side ; if the certificate to be authenticated is not the certificate signed and issued by the first target CA center, acquiring a public key certificate of a second target CA center to which the certificate to be authenticated belongs from a superior trusted CA center, wherein the first target CA center is a CA center that has signed and issued a certificate to the server, the superior trusted CA center is any CA center in the first target CA centers, and the superior trusted CA center and the second target CA center are located in the same trusted environment; and authenticating the certificate to be authenticated by using the public key certificate of the second target CA center. According to the scheme, the problem that in the prior art, if the server side does not store the certificate corresponding to the intelligent card, certificate authentication cannot be achieved is solved. In addition, when all legal CA centers are located in the trusted environment, authentication of all certificates can be achieved through the scheme.

Description

technical field [0001] The present application relates to the technical field of smart cards, in particular to a certificate authentication method, a code number downloading method, a device, a server and a storage medium. Background technique [0002] With the popularity of smart cards, many smart cards (such as eSIM (Embedded Subscriber Identity Module, embedded customer identification module) cards, etc.) are currently widely used in various wearable and Internet of Things terminal devices. Smart cards on such products can often support the download, installation, activation and deactivation of operator code numbers, which solves the problem of resource management waste of operator code numbers to a certain extent. [0003] Referring to the existing operator code number download technology promoted by GSMA (Global System for Mobile Communications Association, the Global System for Mobile Communications Association), the certificate authentication mechanism is used to perf...
