Password card communication method, password card and computer equipment

Abstract

The invention discloses a password card communication method, a password card and computer equipment. The method comprises the following steps that: the password card comprises a PCIe interface, a first conversion module, a USB interface, a second conversion module, a selection module and a password module; the first conversion module converts a PCIe protocol of the PCIe interface into a first protocol and / or the second conversion module converts a USB protocol of the USB interface into a second protocol, wherein the first protocol and the second protocol are the same protocol; the selection module selects a communication signal corresponding to one protocol from the first protocol and the second protocol to communicate with a server, and the password module outputs a password service according to the performed communication, and therefore a function corresponding to the output password service is operated on the server performing the communication. In this way, dual-protocol communication based on a high-speed serial computer expansion bus standard and a universal serial bus can be achieved.

Description

technical field [0001] The invention relates to the technical field of cipher cards, in particular to a cipher card communication method, a cipher card and computer equipment. Background technique [0002] A cryptographic card refers to a cryptographic device with the functions of cryptographic operations, key management, physical random number generation, and the device's own security protection measures. [0003] Cipher cards can be used in communication equipment, computer equipment, and security equipment that require security functions such as cryptographic operations and key management, such as VPN (Virtual Private Network, virtual private network) equipment, CA (Certificate Authority, certificate center) system Related equipment, network cipher machine, security server, security terminal, security management center, key management equipment, etc. [0004] However, the existing encryption card communication scheme is generally based on PCIe (peripheral component inter...

AI Technical Summary

Problems solved by technology

[0004] However, the existing encryption card communication scheme is generally based on PCIe (peripheral component interconnect express, high-speed serial computer expansion bus standard) single-protocol communication, which communicates with the server through the PCIe interface and outputs the password service through the encryption module. Different cryptographic functions can be run on the communicating server, and the dual-protocol communication based on the high-speed serial computer expansion bus standard and USB (Universal Serial Bus, Universal Serial Bus) cannot be realized
