[0002] Password cards are used in the field of information security and are located in the hardware encryption layer of the network security platform. Users can flexibly select cryptographic algorithms to provide cryptographic computing services for upper-layer application systems as needed. Password card virtualization means that based on a single physical password card hardware device, multiple "logical password cards" with the same functions are virtualized for use by multiple virtual machine terminals. Although each terminal shares the same physical password card through a virtual machine, the virtualized "logical password cards" are functionally independent, so they will not affect each other during user use.

There are problems such as uneven password card operation load, local password card operation overload, reduced computing performance, and long user waiting time, which affects the quality of password services. It is impossible to maximize the utilization of password resources and meet the needs of intensive management and use of password resources. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0080] like Figure 1 As shown, a method for centralized management of multiple password cards according to a preferred embodiment of the present application includes:

[0081] S101: Obtain device parameters of each physical password card, and generate multiple virtual password cards according to the device parameters of a single physical password card;

[0082] S102: Establishing a virtual password card resource library, storing all virtual password cards in the virtual password card resource library, and establishing a calling program to generate a virtual password card calling instruction;

[0083] S103: obtaining the virtual password card operation parameters corresponding to the target physical password card according to the preset monitoring node, and determining whether to modify the number of virtual password cards of the target physical password card according to the operation parameters.

[0084] Specifically, when all virtual password cards are stored in the virtual password card resource library, it includes:

[0085] Establishing multiple sub-password card resource libraries according to the virtual password card resource library, and generating index tags of the sub-password card resource libraries;

[0086] Establish a physical password card sequence A, A=(A1,A2…Ai…An), where n is the number of physical password cards and Ai is the i-th physical password card;

[0087] Generate a feature tag based on the device parameters of a single physical password card, and establish a mapping relationship between the password card and the sub-password card resource library based on the index tag and the feature tag;

[0088] All virtual password cards are stored in the corresponding sub-password card resource library according to the password card-sub-password card resource library mapping relationship.

[0089] Specifically, feature tags are generated according to the product parameters of each physical password card, and multiple virtual password cards are established for a single physical password card. Each virtual password card stores a corresponding feature tag, so that multiple user virtual machines can call password card resources at the same time and operate independently of each other.

[0090] Specifically, multiple sub-password card resource libraries can be constructed, and a corresponding relationship between the sub-password card resource libraries and the physical password cards can be established, thereby realizing storage management of virtual password cards.

[0091] In a preferred embodiment of the present application, when establishing a calling program to generate a virtual password card calling instruction, it includes:

[0092] Establish a physical password card association model according to the physical password card sequence A, and generate a sub-password card resource library cross-call model according to the physical password card association model;

[0093] Select the physical password card to be called according to the user's required parameters;

[0094] Select the sub-password card resource library to be called according to the physical password card to be called;

[0095] Traverse all virtual password cards in the sub-password card resource library to be called to determine whether there is an idle virtual password card;

[0096] If there is an idle virtual password card, a first-level call instruction is generated;

[0097] If there is no idle virtual password card, generate the expected waiting time t;

[0098] When the expected waiting time t is less than the preset waiting time threshold, a secondary call instruction is generated;

[0099] When the expected waiting time t is greater than the preset waiting time threshold, a standby sub-password card resource library is selected according to the sub-password card resource library cross-call model, and all standby sub-password card resource libraries are traversed to generate a third-level call instruction.

[0100] Specifically, the first-level calling instruction refers to selecting an idle virtual password card in the sub-password card resource library to be called. The second-level calling instruction refers to waiting first, and when a virtual password card that has completed operation appears, it is set as the virtual password card to be called and called. The third-level calling instruction refers to obtaining the virtual password card resources corresponding to the same physical password card as the physical password card to be called, screening, and selecting a suitable virtual password card for calling. By setting the third-level calling instruction, it is guaranteed that the virtual password card can be called quickly, thereby ensuring the quality of password service.

[0101] Specifically, establishing a physical password card association model means generating the same type of physical password cards according to the operating parameters of each physical password card, that is, setting the physical password cards using the same encryption calculation method as the same type of physical password cards, and establishing a sub-password card resource library cross-call model according to the sub-password card resource library corresponding to the same type of physical password cards.

[0102] Specifically, when generating the expected waiting time t, it includes:

[0103] Obtain the required running time of all virtual password cards in the sub-password card resource library to be called;

[0104] Set the sequence of virtual password cards in the sub-password card resource library to be called according to the required running time;

[0105] Establish a required running time sequence T, T = (t1, t2 ... tm), where m is the number of virtual password cards in the sub-password card resource library to be called, ti is the required running time of the i-th virtual password card in the sub-password card resource library to be called, and t1 ≤ t2 ≤ ... ≤ tm;

[0106] Generate a fluctuation evaluation value according to the operation parameters of the first virtual password card, the second virtual password card and the third virtual password card in the sub-password card resource library to be called;

[0107] Generate compensation coefficient e according to the fluctuation evaluation value;

[0108] Generate the expected waiting time t, t=e*(t1+t2+t3) / 3.

[0109] Specifically, the required running time sequence T is established according to the required running time of each virtual password card in ascending order.

[0110] Specifically, a fluctuation evaluation value is generated according to the user historical demand fluctuation data corresponding to the first virtual password card, the second virtual password card and the third virtual password card. The larger the fluctuation evaluation value, the larger the corresponding compensation coefficient. By dynamically adjusting the compensation coefficient, the expected waiting time is made more accurate.

[0111] In a preferred embodiment of the present application, when determining whether to modify the number of virtual password cards of the target physical password card according to the operating parameters, it includes:

[0112] Select the target sub-password card resource library according to the target physical password card;

[0113] Obtaining the operating parameters of the target sub-password card resource library between the last monitoring time node and the current monitoring time node;

[0114] Generate the average waiting time b of users and the number of waiting users c according to the operating parameters;

[0115] Generate a first evaluation value D1 based on the number of waiting users c;

[0116] Generate a second evaluation value D2 based on the average waiting time b of the user;

[0117] Generate a user evaluation value d=n1*D1+n2*D2, where n1 is the first weight coefficient and n2 is the second weight coefficient;

[0118] A first user evaluation value threshold and a second user evaluation value threshold are preset. If the user evaluation value d of the current monitoring node is greater than the second user evaluation value threshold, a first-level correction instruction is generated. If the user evaluation value d of the current monitoring node is less than the user evaluation value threshold, a second-level correction instruction is generated.

[0119] Specifically, the first evaluation value and the second evaluation value have the same value range. The more waiting users there are, the higher the corresponding first evaluation value is. The longer the user-evaluated waiting time is, the higher the corresponding second evaluation value is.

[0120] Specifically, the first user evaluation value threshold and the second user evaluation value threshold can be set according to historical operation data. When the user evaluation value is between the first user evaluation value threshold and the second user evaluation value threshold, it means that the system is operating normally and can better meet user needs. When it is lower than the first user evaluation value threshold, it means that the current number of users in demand is small, and a secondary correction instruction can be generated to reduce the number of virtual password cards, thereby reducing the loss of physical password cards and improving management efficiency. When it is higher than the second user evaluation value threshold, it means that there are many users in demand at this time, and the current virtual password card cannot meet all the needs, causing the user's waiting time to be too long. A secondary correction instruction can be generated to increase the number of virtual password cards. The specific correction number can be set according to the computing performance required by the user and the parameters of the physical password card to ensure that each virtual password card can meet the user's needs. Improve service quality.

[0141] Set the sequence of virtual password cards in the sub-password card resource library to be called according to the required running time;
