[0038] Compared with the technical solutions in the prior art that have insufficient throughput, slow encryption machine request processing, and high failure rate, the method for distributed application of encryption machines for smart meters / terminals provided in the embodiments of the present invention can realize distributed application of encryption machines for smart meters / terminals, improve the throughput when applying for encryption machines, and thus improve the speed and accuracy of smart meters / terminals applying for encryption machines. The method for distributed application of encryption machines for smart meters / terminals is described in detail below.

[0039] The present invention provides a method for distributed application of encryption machines for smart meters / terminals, which can solve the problems of slow speed and high failure rate caused by insufficient throughput when applying for existing encryption machines. The present invention adopts a distributed method to arrange multiple server terminals for applying for encryption machines on multiple computers, and then uses a load balancing method to evenly distribute the requests to each computer. The present invention can implement distributed application of encryption machines for smart meters / terminals through the following steps. A detailed introduction is given below.

[0040] 1. First, the above step 101 is introduced.

[0041] Before the above steps 101 to 107, some preparatory steps may be included: deploying the encryption machine server method on several computers.

[0042] In the above step 101, each smart meter / terminal initiates an encryption machine request to the load balancing processor. The encryption machine request may include information to be encrypted, smart meter / terminal identification, etc. The smart meter / terminal identification may be the smart meter / terminal name, code, etc.

[0043] 2. Next, the above step 102 is introduced.

[0044] In the above step 102, the load balancing processor receives encryption machine requests initiated by multiple smart meters / terminals, and distributes the encryption machine requests initiated by multiple smart meters / terminals to multiple encryption machine servers in a balanced manner according to the busyness of each encryption machine server, so as to realize efficient processing of encryption machine requests.

[0045] In one embodiment, the encryption machine request may also include encryption priority indication information;

[0046] The load balancing processor receives encryption machine requests initiated by multiple smart meters / terminals, and distributes the encryption machine requests initiated by multiple smart meters / terminals to multiple encryption machine servers in a balanced manner according to the busyness of each encryption machine server, including:

[0047] The load balancing processor receives encryption machine requests initiated by multiple smart meters / terminals, and distributes the encryption machine requests initiated by multiple smart meters / terminals to multiple encryption machine servers in a balanced manner according to the busyness of each encryption machine server and the encryption priority indication information.

[0048] In specific implementation, when performing load balancing, the load balancing processor may not only consider the busyness of each encryption machine server, but also the encryption priority indication information in the encryption machine request, so as to process the encryption machine request according to the priority of the encryption machine request, give priority to processing urgent encryption machine requests, and realize reasonable and efficient scheduling of encryption resources.

[0049] In one embodiment, in the above step 102, the load balancing processor receives encryption machine requests initiated by multiple smart meters / terminals, and distributes the encryption machine requests initiated by multiple smart meters / terminals to multiple encryption machine servers in a balanced manner according to the busyness of each encryption machine server, which may include:

[0050] When the load balancing processor receives encryption machine requests initiated by multiple smart meters / terminals, it initiates an available resource query request to each encryption machine server;

[0051] When each encryption machine server receives a request to inquire about available resources, it feeds back its own resource usage to the load balancing processor;

[0052] The load balancing processor determines the busyness of each encryption machine server based on the resource usage feedback from each encryption machine server; based on the busyness of each encryption machine server, the encryption machine requests initiated by multiple smart meters / terminals are evenly distributed to multiple encryption machine servers.

[0053] In specific implementation, when the load balancing processor receives encryption machine requests initiated by multiple smart meters / terminals, it initiates an available resource inquiry request to each encryption machine server; when each encryption machine server receives the available resource inquiry request, it feeds back its own resource usage to the load balancing processor; the load balancing processor determines the busyness of each encryption machine server based on the resource usage fed back by each encryption machine server; according to the busyness of each encryption machine server, the encryption machine requests initiated by multiple smart meters / terminals are evenly distributed to multiple encryption machine servers, thereby realizing the determination of the busyness of each encryption machine server by round-trip inquiry, which can improve the accuracy and efficiency of load balancing processing.

[0054] In one embodiment, Figure 4 As shown, in the above step 102, the load balancing processor may be a load balancing processor of nginx.

[0055] During specific implementation, the load balancing processing of step 102 is implemented through nginx load balancing (nginx's load balancing processor), and the encryption machine requests of the workshop computer (smart meter / terminal) are submitted to nginx load balancing. Nginx load balancing will evenly distribute these requests to all encryption machine servers, which can improve the efficiency and accuracy of load balancing.

[0056] In one embodiment, the load balancing processor receives encryption machine requests initiated by multiple smart meters / terminals, and distributes the encryption machine requests initiated by the multiple smart meters / terminals to multiple encryption machine servers in a balanced manner according to the busyness of each encryption machine server, which may include:

[0057] The load balancing processor receives encryption machine requests initiated by multiple smart meters / terminals, and maps the encryption machine requests to different encryption machine servers through a hash function according to the busyness of each encryption machine server to achieve load balancing.

[0058] In specific implementation, the load balancing processor receives encryption machine requests initiated by multiple smart meters / terminals, and maps the encryption machine requests to different encryption machine servers through a hash function according to the busyness of each encryption machine server, thereby realizing hash-based polling and improving the efficiency of load balancing.

[0059] In one embodiment, the load balancing processor receives encryption machine requests initiated by multiple smart meters / terminals, and distributes the encryption machine requests initiated by the multiple smart meters / terminals to multiple encryption machine servers in a balanced manner according to the busyness of each encryption machine server, which may include:

[0060] The load balancing processor distributes requests by hashing the smart meter / terminal IP address into an encrypted server IP address, which can implement IP-based hashing and further improve the efficiency of load balancing.

[0061] 3. Again, for ease of understanding, the above steps 103 to 107 are introduced together below.

[0062] During the specific implementation, in this part, the encryption machine server sends the encryption machine request to the encryption machine for processing. After the encryption machine processes the request, it returns the encryption processing result and finally returns it to the workshop computer (smart meter / terminal).

[0063] In the above step 103, each encryption machine server performs encryption preprocessing on each encryption machine request to obtain each encryption machine request after encryption preprocessing, forms an encryption request machine queue for multiple encryption machine requests after encryption preprocessing, and initiates an encryption query request to the encryption machine.

[0064] During specific implementation, some encryption processing work that originally needed to be performed in the encryption machine can be achieved through each encryption machine server in the embodiment of the present invention, that is, each encryption machine server performs encryption pre-processing on each encryption machine request to obtain each encryption machine request after encryption pre-processing, thereby reducing the workload of the encryption machine and improving the processing efficiency of subsequent encryption machines.

[0065] In specific implementation, in an embodiment of the present invention, each encryption machine server also forms an encryption request machine queue for multiple encryption machine requests after encryption preprocessing. By managing the queue, the encryption machine requests are reasonably scheduled, which can improve the efficiency and accuracy of encryption machine request processing.

[0066] In specific implementation, in an embodiment of the present invention, each encryption machine server also initiates an encryption query request to the encryption machine. In one embodiment, in the above step 104, when the encryption machine receives the encryption query request, if it detects that it is in an idle state, it returns encryption machine idle feedback information to the corresponding encryption machine server, which includes:

[0067] When the encryption machine receives an encryption query request, if it detects that it is in an idle state, it estimates the idle time period; based on the estimated idle time period, encryption machine idle feedback information is formed and returned to the corresponding encryption machine server.

[0068] In specific implementation, in an embodiment of the present invention, when the encryption machine receives an encryption query request, if it detects that it is in an idle state, it estimates the idle time period; based on the estimated idle time period, encryption machine idle feedback information is formed and returned to the corresponding encryption machine server, thereby realizing the estimation of the encryption machine time period, and reasonably processing the encryption requests sent by each encryption server according to the estimated time period, which can improve the efficiency of encryption machine request processing.

[0069] In the above step 105, when each encryption machine server receives the encryption machine idle feedback information, it takes out the encryption machine request after encryption preprocessing from the encryption request machine queue and sends it to the encryption machine. The encryption machine request after encryption preprocessing can also include the identification information of the encryption machine server.

[0070] In the above step 106, the encryption machine processes the encryption machine request after encryption preprocessing, obtains encryption machine feedback information, and returns the encryption machine feedback information to the corresponding encryption machine server. Specifically, the encryption machine feedback information can be returned to the encryption machine server corresponding to the identification information based on the identification information of the encryption machine server.

[0071] Step 107: The encryption machine server feeds back the encryption machine feedback information to the corresponding smart meter / terminal through the load balancing processor. When feeding back, the load balancing processor can also set a queue for scheduling and feed back the encryption machine feedback information to the smart meter / terminal corresponding to the smart meter / terminal identifier one by one.

[0072] In a further preferred embodiment of the present invention, the above-mentioned method for applying for a distributed encryption machine for a smart meter / terminal may further include:

[0073] The feedback information of the encryption machine is uploaded to a pre-established blockchain, which can be composed of various ends of the encryption machine system to ensure that the encrypted information cannot be modified, which can improve the security of the encrypted information and the security of the encryption machine processing.

[0074] To sum up, the beneficial technical effect of the method for distributed application of encryption machines for smart meters / terminals provided by the embodiment of the present invention is: the embodiment of the present invention adopts a distributed method, arranges multiple server terminals for applying for encryption machines on multiple computers, and then uses a load balancing method to evenly distribute the requests to each computer, which can solve the problems of slow speed and high failure rate caused by insufficient throughput when applying for existing encryption machines, and can realize distributed application of encryption machines for smart meters / terminals, thereby improving the throughput when applying for encryption machines, and thereby improving the speed and accuracy of smart meters / terminals applying for encryption machines.
