Problems solved by technology

[0004] In addition, after the IoT device is released, its service life is generally relatively long. In order to avoid certain economic losses, as time goes by, the IoT device needs to choose to download the appropriate profile according to the tariff situation, and the CERT_CI and CERT_EUM certificates of the eUICC in the device The usage period is fixed, and once it expires, it can no longer be used to download new profiles
[0005] In addition, after the CERT_EUM certificate is abolished, there is no mechanism to rewrite the certificate. For IoT devices, this situation leads to the same result as the expiration of the CERT_eUICC certificate, which shortens the service life of IoT devices, and even causes IoT devices to waste of resources

Embodiment 1

[0027] figure 2 It is a flow chart of the eUICC renewal method provided by the embodiment of this application. like figure 2 As shown, the renewal method includes the following steps:

[0028] S1: In response to the EUM certificate management server querying that the EUM certificate of the eUICC in the IoT device has expired or been revoked, the EUM certificate management server generates a first asymmetric key pair, that is, the first public key and the first private key, and uses the second A private key to issue a manufacturer's certificate request file (CSR_EUM file), which is used to apply for a new EUM certificate (CERT_EUM).

[0029] S2: The EUM certificate management server initiates a manufacturer certificate request (CSR_EUM) to the CI certificate issuance center, and applies for issuing CERT_EUM.

[0030] Preferably, the EUM certificate management server and the CI certificate issuance center communicate through a network security protocol. For example, securi...

Embodiment 2

[0053] exist figure 2 Based on the flow shown, the image 3 is a block diagram showing the EUM certificate management server.

[0054] like image 3 As shown, the manufacturer certificate management server includes a first communication module 1201, a manufacturer certificate request file issuing module 1202, a manufacturer certificate request module 1203, a first data receiving module 1204, a first verification module 1205, a manufacturer certificate recording module 1206, and a certificate update push module. Module 1207 , second data receiving module 1208 , second verification module 1209 , embedded universal integrated circuit card (eUICC) certificate issuing module 1210 , third data sending module 1211 and update certificate result receiving module 1212 .

[0055] Wherein, the first communication module 1201 is used for communicating with the CI certificate issuing center and the LPA respectively.

[0056] The vendor certificate file issuing module 1202 is configured ...

Abstract

The invention provides a certificate continuing method and a certificate continuing system of an embedded universal integrated circuit card. The method comprises the steps as follows: a manufacturer certificate management server initiates a manufacturer certificate request to a certificate issuing center in response to the condition that a manufacturer certificate of the embedded universal integrated circuit card is overdue or rescinded; the manufacturer certificate management server receives the manufacturer certificate issued by the certificate issuing center; the manufacturer certificate management server records the manufacturer certificate and pushes a certificate update notice to the embedded universal integrated circuit card in equipment of the Internet of Things; the manufacturer certificate management server receives an embedded universal integrated circuit card certificate issuing request of the embedded universal integrated circuit card and issues the new embedded universalintegrated circuit card certificate; and the manufacturer certificate management server distributes the new embedded universal integrated circuit card certificate and the manufacturer certificate to the embedded universal integrated circuit card, and the manufacturer certificate management server receives an update result of the embedded universal integrated circuit card certificate. According tothe method and the system, the service life of the equipment of the Internet of Things is prolonged.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to a method and system for renewing a certificate of an embedded universal integrated circuit card for an Internet of Things device. Background technique [0002] In the field of the Internet of Things, the embedded Universal Integrated Circuit Card (eUICC) is an important component for connecting devices to the network. It realizes network access by downloading and installing the network access profile provided by the operator, but it is not limited to a certain operator. [0003] The manufacturer of eUICC needs to apply for a manufacturer certificate (CERT_EUM) from the CI certificate issuing center. During production, the manufacturer uses the private key of CERT_EUM to issue an eUICC certificate (CERT_eUICC) for each eUICC, and write it into the eUICC together with the root certificate (CERT_CI) and CERT_EUM. CERT_EUM is generally valid for one year, while...
