Description
Technical Field
The present invention relates to the field of network optimization and network security technologies, and in particular, to a method and a system for processing a multi-device access platform.
Background
The internet of things platform is a software system for connecting, managing and monitoring internet of things equipment. These platforms allow for communication between devices, collecting and processing sensor data, performing remote control, and providing data analysis and visualization functions. The core goal of the internet of things platform is to realize interconnection and interworking of equipment and provide more intelligent and efficient service and application for users. When multiple devices are simultaneously accessed into the platform of the internet of things, the concurrent problem of the information queue may be faced, that is, the multiple devices simultaneously send data to the platform, and the platform needs to process the data and respond correspondingly.
In order to cope with congestion and failure of data transmission caused by data transmission when a plurality of terminal devices send data to a platform at the same time, in the prior art, a technical means of message queues and concurrent processing is generally adopted, namely, an internet of things platform stores messages sent by the devices in the queues, and the platform processes the messages sent by the devices one by one according to the sequence of the queues so as to smooth the information sent by the devices and ensure that confusion is not caused by concurrent access. And the concurrent processing technology can be used for processing information sent by a plurality of devices simultaneously, so that the processing efficiency of the platform is improved, and the concurrent pressure is relieved. However, the data transmitted in the message queue is not encrypted, so that sensitive information is easily intercepted and stolen by an attacker, thereby threatening the security of transmission. Lack of a data encryption mechanism may cause security problems such as data disclosure and privacy disclosure, and affect success rate of message transmission. When the concurrent processing of the message queue is performed, resource competition and performance bottleneck exist, for example, too many processing threads cause too high system load, which can cause increase of message processing delay and even system breakdown, thereby affecting success rate of message transmission, and due to introduction of mechanisms such as the message queue, a certain processing delay can be caused under the condition of large message quantity.

Example 1
Referring to fig. 1, fig. 1 is a flow chart of a processing method of a multi-device access platform according to an embodiment of the present invention. The embodiment of the invention provides a multi-device access platform processing method, which comprises steps 101 to 105, wherein the steps are as follows:
Step 101: receiving access request information sent by terminal equipment to a target platform, and sending response information to the terminal equipment based on the access request information; wherein the response information indicates the terminal device to send authentication information.
When the terminal equipment accesses the target platform, the terminal equipment needs to send access request information to the target platform, so as to inform the identity of the platform equipment and the operation to be executed of the terminal equipment, so that the platform can authenticate and authorize the equipment according to the equipment identity and the access request, and the platform can ensure that the equipment can safely access the platform and provide corresponding services and resources for the equipment through the correct access request information. The corresponding response information is fed back by the target platform based on the access request information sent by the terminal equipment, and the formats of access parameters sent by different terminal equipment are standardized based on the response information, so that the platform can quickly know the current state and the requirements of the equipment, and resource allocation and scheduling can be better performed.

In the embodiment of the invention, the response information is used for indicating how the terminal equipment feeds the authentication information back to the target platform. The terminal equipment sends a registration request to the target platform based on the received response information, and the target platform generates a unique digital certificate as an identity certificate of the terminal equipment after receiving the registration request sent by the terminal equipment. Preferably, the terminal device, upon receipt of the unique digital certificate, is also stored in local hardware to prevent unauthorized access and tampering. And then, the terminal equipment sends the generated unique digital certificate to the target platform based on the secure transport layer encryption protocol by the instant TLS protocol so as to verify the identity of the terminal equipment and carry out secure communication.
Step 102: acquiring first authentication information fed back by the terminal equipment, carrying out identity verification on the terminal equipment based on the first authentication information, and sending access indication information to the terminal equipment when the terminal equipment passes the identity verification; the access indication information indicates the terminal equipment to encrypt the initial access parameter based on a preset encryption algorithm so as to generate an encrypted access parameter.
In an embodiment, the obtaining the first authentication information fed back by the terminal device and verifying the identity of the terminal device based on the first authentication information specifically includes: acquiring a unique digital certificate in the first authentication information, extracting a certificate revocation list and a validity period, and rejecting the identity verification of the terminal equipment when the unique digital certificate is included in the certificate revocation list or the unique digital certificate exceeds the validity period; iteratively verifying a certificate chain of the unique digital certificate based on issuer information until a root certificate of the unique digital certificate, and determining that the terminal device passes the identity verification when the root certificate is issued by a trusted root certificate authority.

When the unique digital certificate of the terminal device is included in the certificate revocation list or the digital certificate is not in the validity period, the target platform refuses the authentication request of the terminal device. When the unique digital certificate is not included in the certificate revocation list and the validity period of the unique digital certificate is valid within the current time range, iteratively verifying the certificate chain of the unique digital certificate based on the issuer information. That is, the issuer in the unique digital certificate is checked, and then the whole certificate chain is verified iteratively until the root certificate in the unique digital integer is confirmed to be issued by a trusted root Certificate Authority (CA), at this time, the terminal device is judged to pass the identity verification, and the control target platform sends the access indication information to the terminal device.

In an embodiment of the invention, a pair of random key pairs is generated using an asymmetric encryption algorithm, including a first public key and a first private key. The initial access parameters are encrypted at the terminal equipment based on the first public key so as to ensure the information transmission safety in the communication process. And then, the encryption intervention parameters are sent to the target platform through a preset encryption transmission protocol HTTPS protocol so as to prevent the intermediate man from attacking or eavesdropping in the transmission process. In the embodiment of the invention, the initial access parameters comprise equipment identity identification information, connection parameters, protocol version information and equipment state.

The terminal device provides protocol version information, which can be properly managed and optimized by the target platform. In addition, the initial access parameters include device states, such as "online", "offline", "failure", etc., so that the platform can conveniently know the current state of the terminal device.
Step 103: decrypting the encrypted access parameters to obtain initial access parameters of the terminal equipment; and distributing the initial access parameters to corresponding message queues according to a preset distribution standard, so that the message queues carry out service logic processing on the received initial access parameters.

The processing types of each message queue in the target platform are predefined, the types of access request information corresponding to the initial access parameters are classified each time the message queue receives new initial access parameters, and the distribution of the initial access parameters is realized based on a rule engine technology so as to realize the distribution of the initial access parameters to the corresponding message queues. And then, the responding consumers in different message queues process the access request information in the queues, and proper processing programs or services are distributed to each queue according to the types and the characteristics of the message queues. Preferably, the message queues can be classified according to the type of the access request information and the type of the initial access parameters. For example, a message queue is created for processing access request types as data acquisition requests, and device types as sensors. However, the above solution may cause the created message queue to be too large due to the difference between the request type and the initial access parameter type, so as to occupy too many resources of the platform, and may be adjusted according to the specific application requirements. In performing business logic processing operations for data analysis, a consumer may acquire sensor data from a message queue and process and analyze the data, such as calculating statistics, executing predictive models, detecting anomalies, etc.; when executing the business logic processing operation of the device control, for the device control instructions contained in the message queue, the consumer can be responsible for sending the instructions to the corresponding devices and monitoring the execution results; in performing business logic processing operations for service invocation, the consumer may invoke other services or functional modules, such as storing data and sending notifications, etc., based on the request information in the message.
Step 104: and acquiring a service logic processing result of each message queue to the initial access parameter and distributing the service logic processing result to the corresponding terminal equipment.
And acquiring service logic processing results, such as equipment access success and failure, of each initial access parameter in the message queue, and feeding back the corresponding service logic processing results to the corresponding terminal equipment, thereby completing the information access processing process of the terminal equipment based on the current access request information and the target platform.
Step 105: and monitoring the load speed of each message queue in real time, and carrying out load balancing on the message queues based on the load speed of each message queue.
In an embodiment, the monitoring the load speed of each message queue in real time, and performing load balancing on the message queues based on the load speed of each message queue respectively specifically includes: dividing each message queue into a plurality of partitions and distributing a preset number of consumers in each partition; when the number of the messages to be processed in the first partition exceeds a preset threshold, distributing the messages to be processed in the first partition to a second partition in a message queue corresponding to the first partition; the message processing speed in the second partition is higher than a preset reference value; and when the number of the messages accessed in the message queue exceeds the maximum receiving threshold, increasing the consumers in a preset number of subareas in the message queue.
The message queue is divided into a number of partitions, each of which is processed by one or more consumers. Thus, the partition load balance of the message can be realized, and the processing load of each consumer is ensured to be relatively balanced. When the number of the messages to be processed in the partition exceeds the processing capacity of the partition, namely exceeds a preset threshold, the messages to be processed in the first partition are distributed to other partitions in the message queue where the first partition is located. Preferably, a second partition having a processing speed higher than the reference processing speed is selected. The reference processing speed is preset to process the average duration of a message request by each partition in the message queue. Preferably, further, when the number of messages received by the message queue as a whole exceeds the maximum receiving threshold value which can be born by the message queue, the consumers can be additionally added in the message queue according to the number of the received messages so as to improve the message processing speed. Further, when the number of the messages to be processed in the message queue is small, the number of the consumers in the message queue can be reduced, and the number of the consumers is dynamically adjusted according to the load condition of the message queue.
In one embodiment. The multi-device access platform processing method further comprises the following steps: acquiring historical access request information of the target platform in a preset time period, and training an ARIMA model based on the historical request information so that the ARI MA model outputs a future access request information prediction result of the target platform; and carrying out load balancing on the message queue based on the future access request information prediction result.
The ARI MA model can capture trend information in time series data, thereby helping to know data trends when different devices are connected to the platform. Through trend analysis, the characteristics of periodicity, seasonality and the like of the data can be found, and more comprehensive data insight is provided for the platform. In the embodiment of the invention, the ARI MA model is trained based on the historical access request information received by the target platform in a past period of time. Preferably, data analysis and preprocessing, including data cleansing, outlier handling, missing value filling, etc., are required prior to training to ensure the quality and integrity of the data. Parameters of the ARI MA model are optimized by using proper algorithms and technologies so as to improve the adaptability and prediction accuracy of the model. The best model parameters may be determined using grid search, AI C/bi-ic criteria, etc. The AR I MA model obtained through training can output an access request information prediction result of the target platform in a period of time in the future, and can perform load balancing on a message queue in advance based on the prediction result, so that the message processing capability of the multi-device access is improved.
