Initializing an internal RAM of the PCI cipher card, initializing various peripheral equipment, resetting an algorithm chip and the like. The main control program is also responsible for the work of service receiving and analyzing, scheduling of cryptographic algorithm, bearing key protection system, service sending and the like. The self-diagnosis PCI cipher card software system is realized in the PCI cipher card main control program and comprises a main control working mode switching module, a main control working mode capturing module, a main control self-diagnosis module and a main control state pushing module.

The hardware may be manually set to keep the PCI card operating in a certain state. For example, the PCI password card is configured to be in a self-diagnosis working mode, so that the stability test of the PCI password card can be completed.
The main control self-diagnosis module: the main control self-diagnosis module completes detection of each function in the main control chip, and self-checking result recovery and diagnosis data synthesis are performed. In the diagnosis process, modules such as SM1, SM2, SM3, SM4, SM7, SM9, PCIE modules, other peripheral devices and the like are detected, and at most 32 modules can be supported for detection. Each self-test result is identified by 1bit, 0 indicates pass, and 1 indicates fail.

The main control self-diagnosis module shifts the detection results of the 32 modules to form one int type of diagnosis data, and sends the diagnosis data to the main control state pushing module.
The format of the diagnostic data is as follows:
1. the diagnostic data consists of 32 bits, each bit representing a cryptographic algorithm or functional module diagnostic result. Each bit has an initial value of 0.
2. Each bit has a value of 0 or 1.0 indicates that the diagnosis is passing and the algorithm or function is normal. 1 indicates a diagnostic failure, the algorithm or functional module being abnormal.
3. If each algorithm or functional module is normal, the diagnostic data is 0.
4. If an algorithm or functional module is wrong, the diagnostic data is not 0. The error algorithm or the function module can be rapidly positioned through the corresponding table.
A main control state pushing module: the main control state pushing module is mainly responsible for pushing the working state and the diagnosis data.

The invention provides a self-diagnosis PCI cipher card, which can complete diagnosis of each cipher algorithm and each functional module of the PCI cipher card under the condition of power-up only, complete stability test and display diagnosis conditions to detection personnel, and the detection personnel can intuitively judge whether each module of the PCI cipher card works normally or not, and can accurately position an error module if the work is abnormal.
The work flow of the PCI cipher card for self diagnosis is as follows:
(1) The password card is powered on, and only the power supply module is used for supplying power to the PCIE, so that a PCIE slot inserted in the host is not needed.
(2) The main control program finishes loading the firmware program and all necessary initialization work, and prompts successful loading and successful initialization of the firmware program through the status indicator lamp. And after the main control program is started, the main control working mode capturing module is accessed.
(3) The main control working mode capturing module enters a self-diagnosis mode if the main control working mode capturing module is in the self-diagnosis mode, and otherwise, enters a normal working mode.
(4) After entering the self-diagnosis mode, if the diagnosis is normal, the mode judgment is carried out again by jumping.
(5) After entering the normal working mode, the main control program monitors whether the service needs to be processed or not, and jumps to carry out mode judgment again after the service processing is completed or the service to be processed is not completed.
(6) And (4) and (5) continuously working.
Examples:
the PCI cipher card is provided with a working mode change-over switch which is connected with the GPI pin of the PCI cipher card main control chip. If the GPI pin is 0, the PCI cipher card enters into a normal working mode. The loss of the main control chip can be reduced due to the interrupt mode, and the interrupt mode is adopted in the implementation to realize the main control working mode switching/capturing module. The main control program registers an interrupt processing function, if the GPI pin is 1, the interrupt is triggered, and the interrupt processing function responds. The interrupt processing function internally realizes a main control self-diagnosis module and a main control state pushing module. The main control self-diagnosis module sequentially detects modules such as SM1, SM2, SM3, SM4, SM7, SM9, PCIE modules, other peripheral devices and the like, returns diagnosis results, and shifts the diagnosis results to fill diagnosis data. In the embodiment, 8 modules are detected in total by the cryptographic algorithm and other functional modules, the main control state module outputs diagnostic data by adopting 8 GPO pins of a main control chip, the 8 modules are in one-to-one correspondence with the 8 GPO pins, and the 8 GPO pins are externally connected with red lights. Under normal state, all red lights are extinguished, and if errors occur, the corresponding red lights are lightened by driving to write 1 to the GPO port. If the SM1 algorithm is wrong, the red light corresponding to SM1 is lightened. The main control state pushing module adopts 2 GPO pins of the main control chip to push working states, and the 2 GPO pins are externally connected with green lights. The green light 1 in the self-checking state working mode flashes, the green light 2 in the normal working mode flashes, and the two locking states are extinguished.
By the implementation method, only the PCI cipher card power module is powered, the switch is switched to the self-checking mode, the PCI cipher card green light 1 continuously flashes, and after 24 hours of stability test, no red light is lightened. And disconnecting the SM1 chip, powering on again, switching on the switch to a self-checking mode, flashing the green lamp 1 of the PCI cipher card, and brightening the red lamp corresponding to the SM1 to prompt the self-checking error of the SM1 algorithm. The test further proves that the self-diagnosis PCI cipher card is accurate in detection. The whole process does not use host equipment, windows or Linux operating system, PCI cipher card driver, test program and the like, thereby greatly saving hardware and software resources.
In the present specification, each embodiment is described in a progressive manner, and each embodiment is mainly described in a different point from other embodiments, and identical and similar parts between the embodiments are all enough to refer to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant points refer to the description of the method section.
