example 1

[0215] Such as Figure 8 As shown, this example provides a digital certificate generation method, including:

[0216]Step S1: The provincial company (operator) or equipment manufacturer generates the device identification (ID) and private key of the small base station, and generates a digital certificate of the self-signed small base station. The ID includes the serial number part, the random number part, and the verification part to ensure that it is not duplicated by others and will not be generated by others. The blockchain certificate contains the small base station ID, thereby ensuring that a small base station corresponds to a blockchain certificate.

[0217] Step S2: The provincial company or / equipment vendor initiates the reporting of the digital certificate, and reports the digital certificate of the small base station to the blockchain digital certificate system. The communication operator referred to by the provincial company here corresponds to a communication dev...

example 2

[0224] The difference between this example and Example 1 is that the small base station does not directly store digital certificates, but only stores information such as public keys and device identifiers. The generation of the digital certificates includes:

[0225] The provincial company / equipment manufacturer generates the ID, private key, and public key of the small base station, and installs the ID, private key, and public key to the small base station on the production line of the small base station. Among them, the ID includes a serial number part, a random number part, and a verification part to ensure that it is not duplicated by others and will not be generated by others.

[0226] The provincial company / equipment manufacturer produces a self-signed certificate based on the ID, private key, and public key of the small base station. The certificate contains the ID of the small base station, thereby ensuring that a small base station corresponds to a blockchain certifica...

example 3

[0236] This example provides a digital certificate authentication method, including:

[0237] After the security gateway receives the digital certificate of the small base station, it verifies the legitimacy of the small base station certificate, including: whether the certificate identifier of the digital certificate (for example, the certificate name) matches the ID of the small base station, and whether the digital certificate is valid, and then sends The blockchain digital certificate system queries the status information of the digital certificate, and the query request contains certificate information, such as the complete digital certificate or the hash value of the digital certificate.

[0238] The blockchain digital certificate system searches for the latest status information of the certificate based on the certificate information, and returns the status information to the security gateway.

[0239] The security gateway authenticates the digital certificate of the sm...

Abstract

The embodiment of the invention discloses digital certificate generation and authentication methods, communication equipment and a storage medium. The digital certificate generation method provided bythe embodiment of the invention comprises the following steps that: predetermined equipment acquires an equipment identifier and a public key of a base station, wherein the predetermined equipment isa base station using a digital certificate, manufacturer equipment of a manufacturer for producing the base station or operator equipment of an operator applying the base station; and the digital certificate is generated according to the equipment identifier and the public key, wherein the digital certificate is used for allowing a blockchain digital certificate system to generate a certificate block, and takes effect after the certificate block passes through consensus mechanism-based verification.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a generation and authentication method of a digital certificate, a communication device and a storage medium. Background technique [0002] A digital certificate is a string of numbers that marks the identity information of each party in Internet communication, and provides a way to verify the identity of a communicating entity on the Internet. A digital certificate is not a digital ID card. For example, a network element of a gateway or a core network needs to use a digital certificate installed in the base station to authenticate the base station. [0003] The base station may be various types of base stations, such as small base stations, micro base stations, and home base stations. The Home Base Station, also known as HeNB, (Home evolved Node B, Home Evolved Base Station), is a miniaturized, low-power cellular technology, which is connected to the mobile core ne...
