Abstract

The invention relates to a security certificate updating method. The method comprises the following steps: after a client establishes a connection with a server, the client receives a certificate updating notification sent by the server when a certificate needs updating; after receiving the certificate updating notification, the client sends identity identification information to the server; the client receives a certificate updating command which is sent when the server determines the client is qualified for carrying out certificate updating, and generates a certificate signature request comprising a security certificate preparation file after receiving the certificate updating command; the client sends the certificate signature request to the server; and the client receives the security certificate file sent by the server. According to the security certificate updating method provided in the embodiment of the invention, cost on manual maintenance which is performed by workers on the client can be avoided, and the maintenance efficiency of the remote client is improved.

Description

technical field [0001] The invention relates to the field of the Internet, in particular to a method for updating a security certificate, a client and a server. Background technique [0002] Certificates are a means of protecting data transmission and are widely used in fields such as finance and communications. The issuance and maintenance of certificates in the current technology basically refer to the Public Key Infrastructure (PKI) specification, using USB key and other transfer methods to transfer certificates, and manual participation is often required when updating is required. [0003] However, for clients that need to be remotely controlled, such as home meters (eg, gas meters, electric meters), etc., these clients can be intelligently controlled by connecting to a remote server through the Internet, and perform operations such as meter reading, reading, and billing. For data security, the server usually installs a certificate for the client to achieve security con...
