Encryption card and encrypted message processing method thereof

Abstract

The invention relates to an encryption card and an encrypted message processing method thereof. The method comprises the following steps that: a CPU data core acquires a message to be processed; constructing a first descriptor based on a protocol of the encrypted message; writing the first descriptor into a hardware queue; an FPGA analyzing the first descriptor to generate an operation instruction; and the FPGA sending the operation instruction to an encryption and decryption chip to process the encrypted message. According to the method for processing the encrypted message by the encryption card, electronic equipment and a computer readable medium, the queue utilization rate in the encryption card can be improved, processed descriptors can be recovered in time, more messages enter the queue, the problem of packet loss caused by the fact that the messages cannot enter the queue due to full queue is solved, and the encryption card processing efficiency is improved.

Description

technical field [0001] The present disclosure relates to the field of computer information processing, and in particular, relates to an encryption card and a method for processing encrypted messages, electronic equipment, and a computer-readable medium. Background technique [0002] IP Security (IP Security, hereinafter referred to as: IPSec) protocol suite is a series of protocols developed by the Internet Engineering Task Force (Internet Engineering Task Force, referred to as: IETF), which provides high-quality, interoperable, cryptography-based The security policy provides protection for the IP layer or above the IP layer. Specific communication parties use encryption and data source verification at the IP layer to ensure the privacy, integrity, authenticity and anti-replay of datagrams when they are transmitted on the network. Existing IPSec achieves the above goal mainly through two security protocols, an Authentication Header (AH for short) protocol and an Encapsulati...

AI Technical Summary

Problems solved by technology

[0005] In view of this, the present disclosure provides an encryption card and its method for processing encrypted messages, an electronic device, and a computer-readable medium, which can improve the utilization rate of queues in the encryption card, and at the same time recover the processed descriptors in time. Make more packets enter the queue, solve the problem of packet loss caused by the inability to enter the queue because the queue is full, and improve the processing efficiency of the encryption card
