Such a method requires maintenance of the server device, and is large in maintenance workload, not suitable for use in the order of millions of users, and high in hardware cost.
Based on the above, the embodiment of the invention provides a method and a device for calling a digital certificate, which are used for solving the problem of high cost for maintaining server equipment caused by adopting a soft certificate mode in the prior art. The method, the device and the system are based on the same inventive concept, and because the principles of solving the problems by the method, the device and the system are similar, the implementation of the method, the device and the system can be mutually referred to, and the repetition is not repeated.
For easy understanding, the embodiment of the invention first describes a digital certificate calling system.
Referring to fig. 1, an embodiment of the present invention provides a system 100 for invoking digital certificates, including a server 101 and one or more terminal devices, where fig. 1 illustrates one terminal device 102.
The server 101 is configured to request, from the terminal device 102 coupled with the tax control device 103, acquisition of authentication information generated based on the digital certificate in the tax control device 103, so as to complete the foregoing authentication process when the service platform 104 operates.
The verification information comprises an encryption character string corresponding to the digital certificate, which changes according to a preset period, has certain timeliness, ensures that the obtained verification information can be used for verifying the identity of the user only in the validity period, and avoids response business risks caused by the fact that the verification information is always valid. In the implementation, the verification information can be generated and updated by the tax control equipment based on the digital certificate, and can be read and called by the terminal equipment coupled with the tax control equipment.
The terminal device 102 is configured to obtain, in response to a request from the server 101, authentication information generated based on the digital certificate through the tax control device coupled to the terminal device, and send the authentication information to the server 101.
The manner in which the terminal device 102 is coupled to the tax control device may be through bluetooth, wireless, or an external device interface, such as when the tax control device is a USB device, the terminal device may be inserted into the terminal device based on the USB interface on the terminal device to implement coupling between the terminal device and the target tax control device, and specifically, the tax control device may be a digital certificate for storing the identity of the user, such as a gold tax disc, a gold tax disc-M, a tax disc, a haitaikey, a text tripod creating USB KEY, a holding USB KEY, or the like.
In the embodiment of the present invention, the server 101 determines to request the terminal device 102 coupled with the tax control device 103 for obtaining the authentication information, so as to perform the authentication on the service platform 104. The digital certificates corresponding to all enterprise users are not required to be stored and managed by the special server equipment, the maintenance workload and hardware cost of maintaining the server equipment can be reduced, and the method is suitable for the situation that the number of enterprise users is large. Furthermore, to facilitate understanding of the interactions between the foregoing devices, a tax control device 103 and a service platform 104 are also illustrated in fig. 1.
In an optional implementation manner, the server may be a cloud server indicating the aforementioned entry channel cloud, and based on the acquired verification information, complete identity verification on the service platform to obtain a token (token) fed back by the service platform, so that the service platform provides an entry invoice service for the user; in another alternative, the server may be a proxy server of the aforementioned inbound channel cloud, which may be referred to as a channel proxy. The channel proxy completes identity verification on the service platform based on the acquired verification information to obtain a token fed back by the service platform, and sends the token to the entry channel cloud to complete the butt joint between the entry channel cloud and the service platform. In the subsequent business interaction, the channel proxy is used as an intermediate interface between the entry channel cloud and the user interaction, namely, the channel proxy receives a business request initiated by the user and sends the business request to the entry channel cloud, and the entry channel cloud returns an execution result to the channel proxy after carrying out corresponding business interaction with the service platform based on the business request and returns the execution result to the user through the channel proxy.
In an alternative embodiment, the communication between the server and the one or more terminal devices is based on a transmission control protocol (TCP, transmission Control Protocol) long connection. In this embodiment, when the terminal device determines that the terminal device is coupled with the tax control device, the request of the long TCP connection is initiated to the server, and the server accepts the request of the long TCP connection to establish a secure and stable communication connection mechanism, i.e., long TCP connection with the terminal device. Based on the keep-alive function of the TCP long connection, the connection is not actively closed after being established, and interaction between the two parties can continue to use the connection within the protection timing; in the implementation, the server may further send a detection message segment to the terminal device when there is no data interaction between the terminal device and the server within a preset period of time, for example, two hours, so as to detect the state of the terminal device to determine whether the TCP long connection is closed.
In an alternative embodiment, an executable program exe (hereinafter, simply referred to as a management program) for managing the tax control apparatus may be installed on the terminal apparatus, and the management program is responsible for listening to a request sent by the server to acquire authentication information generated based on the digital certificate in the tax control apparatus, and saving the apparatus information of the tax control apparatus to the server and notifying the server to update the apparatus information of the tax control apparatus saved therein. According to the embodiment of the invention, the management program is installed, and verification information is acquired in a mode that the dll plug-in is not called by the browser, so that the situation of acquisition operation errors caused by incompatibility of the dll plug-in by the browser can be avoided.
When the method is implemented, before data such as equipment information and the like are transmitted between the management program and the server, the client certificate and the channel proxy server certificate are adopted to carry out identity authentication, and the method can be realized by calling a digital certificate interface. After the identity authentication is completed, a secure channel between the management program and the server is established, and the management program transmits data such as equipment information and the like to the server through the secure channel in an xml mode.
Specifically, taking the manner that the tax control equipment is inserted into the USB interface of the terminal equipment as an example, the management program can automatically detect whether the tax control equipment is inserted into the terminal equipment or not during running. When the insertion of the tax control equipment is detected, equipment information of the tax control equipment is obtained, and the equipment information (equipment number, tax number, network connection or not and equipment insertion state) and related network information (mode setting, protocol type, remote access password setting or not, tax control equipment password setting or not, channel proxy IP, channel proxy port, remote equipment IP and remote equipment port) are displayed on a management program interface. Transmitting the equipment information (equipment number, tax number, protocol type, equipment insertion mark and network password) of the tax control equipment inserted into the terminal equipment to a server through a secure channel for storage; when the tax control equipment on the terminal equipment is detected to be removed, the equipment number, tax number and equipment removal mark of the tax control equipment are sent to a server through a safety channel, so that the server updates the stored equipment information of the tax control equipment, namely, the state mark in the equipment information is changed into the removal mark; when the fact that the tax control equipment is inserted into the terminal equipment but the network connection state is disconnected is detected, the network connection is retried, equipment information (equipment number, tax number, protocol type, equipment insertion mark and network password) of the tax control equipment is sent to the server when the connection is successful, and if the retry is failed for a plurality of times, error information for prompting the network connection failure is output.
In specific implementation, the version number of the management program can be configured in the server, and the version number can be uploaded to the server periodically when the management program runs, so that the server can perform version verification and update the management program in time. When the server determines that the version number of the current configuration is smaller than or equal to the version number uploaded by the management program, the server does not operate; when the version number of the current configuration is determined to be greater than the version number uploaded by the management program, the download address of the upgrade management program is returned to the management program, so that the installation download address of the management program obtains the installation upgrade package, and the upgrade program is started to upgrade the version of the management program when the download is successful.
