According to the encryption and decryption method based on the hard pipeline, disclosed by the invention, the hard pipeline technology is adopted to carry out hard pipeline isolation on the high-priority flow and the low-priority flow, so that the high-priority flow is ensured to be subjected to priority processing in a full pipeline, resources cannot be occupied by the low-priority flow, and the requirement of certainty and low time delay of edge computing safety is met.
As shown in fig. 1, the encryption and decryption method based on hard pipe disclosed in the present invention includes the following steps:
s100, receiving the message, identifying whether the message needs to be encrypted and decrypted according to information carried by the message, dividing the message into hard pipelines with different priorities, and further sending the message in different hard pipelines into corresponding hard pipelines in the direction processing module;
specifically, the edge network switching device generally includes an ingress direction processing module for forwarding a packet, a queue scheduling module, an egress direction processing module, and an encryption/decryption module for encrypting/decrypting the packet. In order to ensure that the high-priority flow can be processed preferentially and cannot occupy resources by the low-priority flow, a plurality of hard pipelines with different priorities are arranged in the incoming direction processing module, the queue scheduling module, the outgoing direction processing module and the encryption and decryption module, and the hard pipelines are used for carrying out hard pipeline isolation processing on the flows with different priorities, so that the high-priority flow certainty low time delay is ensured.
After receiving the message, the edge network switching device may obtain some information carried by the message, such as an IP address, a UDP port number, a Priority (Priority), and the like, by analyzing the message. After the above information is obtained, whether the packet needs to be encrypted and decrypted can be identified according to the IP address, UDP port number, and the like carried by the packet, and the packet is divided into hard pipes with different priorities according to the priority of the packet, as shown in fig. 2, the network switching device adopts two hard pipes, one is a hard Pipe1 used by a high-priority packet, and the other is a hard Pipe0 used by a low-priority packet, where the hard Pipe1 is forwarded corresponding to a high-priority MAC, the hard Pipe0 is forwarded corresponding to a low-priority MAC, that is, the high-priority packet is forwarded to the hard Pipe1, and the low-priority packet is forwarded to the hard Pipe 0.
After the messages are divided into the hard pipelines with different priorities and the data caching and assembling of the received messages are completed, the messages in the corresponding hard pipelines are further sent into the corresponding hard pipelines in the direction processing module according to the serial numbers (Channel IDs) of the hard pipelines, for example, the messages divided into the high-priority messages in the hard pipeline Pipe1, the messages can be determined to be sent into the hard pipeline Pipe1 in the direction processing module according to the serial number 1 of the corresponding hard pipeline, and the messages are further sent into the hard pipeline Pipe1 in the direction processing module.
In this embodiment, no matter the message needs to be encrypted or decrypted or the common message, the serial number of the hard pipeline occupied by the message is sent to each module, so that each module can send the message to the corresponding hard pipeline according to the serial number of the hard pipeline.
S200, the incoming direction processing module performs table look-up processing on the messages in different hard pipelines, and performs queue scheduling through the queue scheduling module, and the queue scheduling module sends the messages in different hard pipelines into corresponding hard pipelines in the outgoing direction processing module according to the priority and the serial numbers of the hard pipelines.
Specifically, the incoming direction processing module searches and processes forwarding entries for messages in different hard pipelines, and may obtain an editing behavior and a forwarding behavior of the message, for example, search and process forwarding entries for messages in hard pipelines Pipe1 and Pipe0, respectively, and obtain an editing behavior and a forwarding behavior of the message.
After searching and processing the forwarding table entry, the scheduling module further performs packet in-queue and out-queue processing, the queue scheduling module sends the packets in different hard pipes into corresponding hard pipes in the out-direction processing module according to the priorities and the numbers of the hard pipes, that is, forwards the packets in the corresponding hard pipes to the corresponding hard pipes in the out-direction processing module according to the order from high priority to low priority, for example, for a hard Pipe1 used for high priority traffic and a hard Pipe0 used for low priority traffic, firstly forwards the packets in the hard Pipe1 to the hard Pipe1 of the out-direction processing module according to the numbers of the hard pipes, and finally forwards the packets in the hard Pipe0 to the hard Pipe0 of the out-direction processing module according to the numbers of the hard pipes.

Further, in the encryption and decryption module, the message with the relatively high Priority is assigned to the hard pipeline with the relatively high Priority for forwarding and encryption and decryption, the message with the relatively low Priority is assigned to the hard pipeline with the relatively low Priority for forwarding and encryption and decryption, that is, the message enters the corresponding hard pipeline for forwarding and encryption and decryption according to the Priority, and meanwhile, the hard pipelines with different priorities adopt an SP (Strict Priority) scheduling algorithm for queue scheduling, so that the message in the hard pipeline with high Priority can be preferentially processed.
