Exemplary method
Fig. 1 is a flowchart illustrating a cooperative dynamic scheduling method for cryptographic resources according to an exemplary embodiment of the present invention. The embodiment can be applied to an electronic device, as shown in fig. 1, and includes the following steps:
step 101, obtaining password resource demand information corresponding to a target application system.
As an embodiment, before obtaining the password resource requirement information corresponding to the target application system, the method includes: storing all operation resources and password resources in a centralized and classified manner to construct a resource pool; collecting password resource demand information, password equipment operation capacity and operation parameter information of each application system; and distributing a corresponding number of fixed password service units and password resources for each application system from the resource pool according to the password resource demand information.
Generally, before the cooperative dynamic scheduling of the cryptographic resources, a resource pool needs to be constructed. Specifically, each operation resource, password resource and the like are classified and stored in a pool to construct a resource pool. Therefore, resources can be extracted from the resource pool as required, and the resources are released when no requirement exists. The resource pool comprises a hardware cipher machine resource pool, a virtual cipher machine resource pool and a key database resource pool.
The hardware cipher machine resource pool mainly comprises a hardware cipher machine cluster which is used for providing cipher operation functions, including a symmetric algorithm, an asymmetric algorithm and a digest algorithm, and simultaneously providing a security protection function for a security system core element key. The virtual cryptographic machine resource pool mainly comprises a virtual cryptographic machine cluster which is mainly used for partitioning hardware resources through a virtualization technology, multiple virtual machines are simulated on a physical host, functions of the virtual cryptographic machine are consistent with those of an entity machine, and the utilization rate of the hardware resources is enhanced. The key database resource pool is mainly used for realizing the isolated storage of the keys of each application system.
Further, referring to fig. 2, basic resource configuration is required before performing the cooperative dynamic scheduling of the cryptographic resources. Specifically, first, service requirements (corresponding to the cryptographic resource requirements of the application system), the computing power of the cryptographic device, and parameter information are collected. And then distributing a corresponding number of fixed password service units and password resources for each application system from the resource pool according to the password resource demand information. The cryptographic resources may include, among other things, physical cryptographic devices and virtual cryptographic device resources. The collected computing power and parameters of the cryptographic device include: supported cryptographic algorithms, operational performance of each cryptographic algorithm, concurrent connectivity, and the like.
As an embodiment, before obtaining the password resource requirement information corresponding to the target application system, the method includes: and monitoring the running state of the password resources associated with each application system, and obtaining each running parameter from the password resources so as to obtain the running information of the password resources corresponding to each application system.
Specifically, referring to fig. 2, before performing cooperative and dynamic scheduling of the password resource, the running state of the password resource associated with each application system needs to be monitored, and each running parameter needs to be obtained from the password resource, so as to obtain the running information of the password resource corresponding to each application system. And when the data flow of the application system is monitored to be stable, the password service is completed by the fixed password service unit and the password resource. And after monitoring that the traffic of the application system changes, starting the password resource cooperative dynamic scheduling system to perform dynamic resource allocation.
As an embodiment, the method for collaborative and dynamic scheduling of cryptographic resources further includes: and setting the password resource scheduling threshold value of each application system according to the collected password resource demand information of each application system.
Generally, after collecting the corresponding information, the cryptographic resource scheduling threshold of the specific service application system needs to be set according to the collected cryptographic resource requirement information of each application system. The cipher resource scheduling threshold comprises a highest threshold Simax and a lowest threshold Simin, and subsequently, a decision can be made according to the two thresholds to judge whether the cipher resource needs to be scheduled to the application system, wherein i represents the ith application system.
102, calculating a load value of the password resource currently used by the target application system based on a preset decision algorithm, and judging whether password resource scheduling needs to be performed on the target application system according to the load value.
Generally, according to the collected running information of the password resources, a weighted dynamic adaptation algorithm is adopted to calculate a load value of the password resources currently used by the target application system, and then whether the password resources corresponding to the target application system need to be dynamically adjusted, that is, whether the resources need to be increased or decreased, is determined.
As an embodiment, calculating a load value of a cryptographic resource currently used by a target application system based on a preset decision algorithm includes: acquiring password resource operation information corresponding to all application systems; calculating the load value of each password resource in the resource pool according to the password resource operation information; and calculating the total load value of all the password resources currently associated with the target application system according to the basic information and the load value of each password resource, wherein the total load value is used as the load value of the password resource currently used by the target application system.
Specifically, after collecting the running information of the password resources corresponding to all the application systems, obtaining the real-time load value Si of each current application system by adopting a comprehensive calculation method, and comparing the real-time load value Si with an initially set high threshold value Simax and a lowest threshold value Simin for decision making. Because the calculation of the real-time load value Si of each application system has high complexity, the available operating parameters of each device are more, and the number of password resource devices corresponding to each application is large, it is difficult to accurately calculate the comprehensive load of the password resources used by the current application. The invention realizes the dynamic load calculation by a weighted dynamic adaptation algorithm based on the characteristics of the password resource equipment, and can effectively meet the requirement of the actual dynamic password resource scheduling. The specific real-time load calculation process of the service is as follows:
(1) first, load calculation for each cryptographic resource needs to be implemented. Specifically, the password resource operation information corresponding to all the application systems is obtained, and the load value of each password resource in the resource pool is calculated according to the password resource operation information. And each password resource is a hardware password machine resource or a virtual password machine resource.
(2) Secondly, obtaining the total load condition of all the password resources related to the application system according to the basic information and the real-time load value of each password resource, namely calculating the total load value of all the password resources currently related to the target application system.
As one embodiment, calculating a load value for each cryptographic resource in the resource pool based on the cryptographic resource run information includes: determining a first ratio of the operational performance and the total performance of the current cryptographic function according to the running information of the cryptographic resource; determining a second ratio of the number of concurrent connections to the maximum nominal number of concurrent connections according to the password resource operation information; determining the resource occupancy rate of a target application system according to the running information of the password resources; and determining the load value of each password resource in the resource pool based on the first ratio, the second ratio and the occupancy rate of the target application system resource.
Referring to fig. 3, the detailed process of calculating the load value of each cryptographic resource in the resource pool according to the cryptographic resource running information is as follows:
1) determining the ratio of the current operation performance of each cryptographic function to the maximum performance of the resource, accumulating the ratios to obtain X1 (corresponding to a first ratio), and if X1>1, revising X1= 1;
2) determining a ratio X2 (corresponding to a second ratio) of the number of concurrent connections to the maximum nominal number of concurrent connections;
3) determining the CPU occupancy rate O and the memory occupancy rate M, and calculating to obtain the resource occupancy rate X3 of a target application system, wherein X3= Min (100, Max (O, M));
4) and calculating by adopting a dynamic adaptation algorithm based on the three numerical values to obtain the load value Sdi of each password resource. If X1=1 or X3=1, Sdi =1, otherwise, the calculation formula is:
Sdi = Min(100, 100*(X1+(W2*X2+W3*X3)/ (W2+W3)))
wherein, W2 is the number of concurrent connections, W3 is the weight value of the CPU memory resource occupancy rate value, the suggested values 10 and 90 can be adjusted according to the actual equipment cryptographic algorithm capability.
As an embodiment, calculating an overall load value of all the cryptographic resources currently associated with the target application system according to the basic information and the load value of each cryptographic resource includes: calculating the capability value scores of the password resources currently associated with the target application system as load weight values according to the nominal information of the password resources currently associated with the target application system; and calculating the total load value of all the password resources currently associated with the target application system according to the load value of each password resource in the resource pool and the load weight value of each password resource currently associated with the target application system.
Referring to fig. 3, the calculation process of the overall load value of all the cryptographic resources currently associated with the target application system is as follows:
1) calculating the capability value score Ni of each associated password resource according to the actual nominal information of the password resource currently associated with the target application system, taking the value of 0-100 as the load weight value;
2) and according to the obtained load value Sdi of each password resource, then according to the load weight value in 1), carrying out weighted average to obtain an overall load value Si.
Si=(N1*S1+N2*S2+…+Nn*Sn)/(N1+N2+…+Nn)
And the Nn is the capability value score of the nth password resource associated with the target application system, and the Sn is the load value of the nth password resource associated with the target application system.
As an embodiment, determining whether to perform cryptographic resource scheduling on a target application system according to a load value includes: comparing the load value of the password resource currently used by the target application system with a preset password resource scheduling threshold value; and judging whether password resource scheduling needs to be carried out on the target application system according to the comparison result.
Specifically, after collecting the password resource operation information corresponding to all application systems, obtaining the total load value Si of all password resources currently associated with the application systems by using a comprehensive calculation method, comparing the total load value Si with the initially set highest threshold value Simax and lowest threshold value Simin, and determining whether to perform password resource scheduling on the target application system according to the comparison result. For example, but not limited to, when the comparison result is that the overall load value Si is greater than the highest threshold value Simax, it is determined that the cryptographic resource scheduling needs to be performed on the target application system. And when the comparison result is that the total load value Si is smaller than the minimum threshold value Simin, judging that the password resource scheduling needs to be carried out on the target application system.

Therefore, after combining the system and method for cooperative dynamic scheduling of password resources proposed in this embodiment, the method for cooperative dynamic scheduling of password resources can be implemented by using the system for cooperative dynamic scheduling of password resources shown in fig. 5, and the implementation steps are as follows:
the first step is as follows: and basic resource allocation, namely firstly collecting service requirements, computing capacity of password equipment and parameter information by a basic allocation module of the password resource collaborative dynamic scheduling system, and then allocating a corresponding number of fixed password service units and password resources to an application system according to the service requirements. When the resource monitoring module monitors that the data flow of the application system is stable, the password service is completed by the fixed password service unit and the password resource. And when the traffic volume changes, starting the password resource cooperative dynamic scheduling system to perform dynamic resource allocation.
The second step is as follows: after collecting the corresponding information, the parameter configuration module of the code resource cooperative dynamic scheduling system sets the code resource scheduling threshold of each application system.
The third step: the resource monitoring module of the code resource collaborative dynamic scheduling system monitors the running state of the code resource in real time, obtains various running parameters from the code resource and sends the running parameters to the decision module in fixed time.
The fourth step: the decision module calculates to obtain a load value by adopting a weighted dynamic adaptation algorithm according to the collected password resource operation information, then judges whether the password resource corresponding to the application system needs to be dynamically adjusted, namely whether the resource needs to be increased or reduced, and sends the decision information to the resource scheduling module.
The fifth step: after receiving the strategy of resource increase, the resource scheduling module selects a certain amount of idle resources and dynamically adds the idle resources to the password resources required to be allocated by the current application. After receiving the strategy of password resource reduction, corresponding resources are recovered from the password resources which provide service for the application system at present, and the resources are marked to be in an idle state in the password resource collaborative dynamic scheduling system.
A sixth step: and repeating the third step to the fifth step until the password resource meets the requirements of each application system.
In the first step, a basic configuration module in the cooperative dynamic scheduling system of the password resources collects the password computing capacity and various parameters of all password equipment resources in the system. The password resource types can include an entity password device and a virtual password device resource. The collected device resource computation capabilities and parameters include: supported cryptographic algorithms, operational performance of each cryptographic algorithm, concurrent connectivity, and the like.
Meanwhile, the parameter configuration module needs to set a password resource scheduling threshold for the application system, including a highest threshold value Simax and a lowest threshold value Simin, and the decision module makes a decision according to the two threshold values, where i represents the ith application system.
In the fourth step, after the decision module collects password resource operation information corresponding to all application systems, a comprehensive calculation method is adopted to obtain a real-time load value Si of each current application system, the current load value Si is compared with an initially set high threshold value Simax and a lowest threshold value Simin for decision, and scheduling information is sent to the resource scheduling module according to a comparison decision result.
The calculation of the real-time load value Si has high complexity, the available operating parameters of each device are more, and the password resource devices corresponding to each application are numerous, so that it is difficult to accurately calculate the comprehensive load of the password resources used by the current application. The invention realizes the dynamic load calculation by a weighted dynamic adaptation algorithm based on the characteristics of the password resource equipment, and can effectively meet the requirement of the actual dynamic password resource scheduling. The specific real-time load calculation process of the service is as follows:
(1) firstly, load calculation for each password resource needs to be realized, and the calculation process is as follows:
1) determining the ratio of the current cryptographic function operation performance to the maximum performance of the resource, accumulating the ratios to obtain X1, and if X1 is greater than 1, revising X1= 1;
2) determining the ratio X2 of the number of concurrent connections to the maximum nominal number of concurrent connections;
3) determining the CPU occupancy rate O and the memory occupancy rate M, and calculating to obtain the resource occupancy rate X3 of a target application system, wherein X3= Min (100, Max (O, M));
4) and calculating by adopting a dynamic adaptation algorithm based on the three numerical values to obtain the load value Sdi of each password resource. If X1=1 or X3=1, Sdi =1, otherwise, the calculation formula is:
Sdi = Min(100, 100*(X1+(W2*X2+W3*X3)/ (W2+W3)))
wherein, W2 is the number of concurrent connections, W3 is the weight value of the CPU memory resource occupancy rate value, the suggested values 10 and 90 can be adjusted according to the actual equipment cryptographic algorithm capability.
And each password resource is a hardware password machine resource or a virtual password machine resource.
(2) And secondly, obtaining the total load value of all the password resources related to the application system according to the basic information of each password resource and the numerical value of the real-time load. The calculation process of the total load value Si of all the password resources related to the application system is as follows:
1) calculating the capability value score Ni of each password resource according to the actual nominal information of the password resource currently associated with the application system, taking the value of 0-100 as the load weight value;
2) and (3) carrying out weighted average according to each password resource load value Sdi obtained in the step (1) and the weight value in the step (1) to obtain an overall load value Si.
Si=(N1*S1+N2*S2+…+Nn*Sn)/(N1+N2+…+Nn)
And the Nn is the capability value score of the nth password resource associated with the service application, and the Sn is the load value of the nth password resource associated with the service application.
In the fifth step, after receiving the resource adjustment strategy, the resource scheduling module determines the amount of the loaded or released resource according to the comparison result of the real-time load value and the threshold value, so as to achieve the final dynamic scheduling of the resource, wherein the specific scheduling resource load amount allocation process is as follows:
(1) calculating the ability score Ni of each password resource according to the calculation ability and parameters of the initial password resource, and taking the value of 0-100;
(2) obtaining the capability scores of all password resources related to the current application, and calculating a total score CALL;
calculating a ratio T of resources to be increased or decreased according to a difference value between the load value and a median of threshold values (mean Savr = (Smax-Smin)/2), wherein T = (S-Savr)/Savr, the resources are required to be increased if T is a positive value, and the resources are decreased if T is a negative value;
(3) calculating to obtain a score value C = CALL | T | of the difference between the load value and the median of the threshold value according to the total score value CALL and the resource increase and decrease ratio calculated in the step (2);
(4) if the password resources need to be added, loading new password resources according to the score value C;
(5) if the password resources need to be reduced, the redundant password resources are released according to the credit value C.
Therefore, the cooperative dynamic password resource scheduling system provided by this embodiment can perform dynamic calculation according to the real-time use state of the password resource in the application of the password service, automatically implement scheduling and allocation of the password resource, effectively solve the problem of dynamic password resource scheduling, implement dynamic allocation or release of the password resource according to the increase or decrease of the service demand, optimize the reasonable use of the password resource, and thereby improve the password resource utilization rate and the password service efficiency. And then solved the unable dynamic scheduling and optimal configuration password resource that exist among the prior art to lead to the technical problem that the utilization ratio of password resource is low, password service efficiency is poor.
