Cryptographic device and cryptographic apparatus

Abstract

The invention discloses a cryptographic device and a cryptographic apparatus. The cryptographic device comprises a PCIe interface, a power supply, a power supply management module, a universal serialbus concentrator, a mobile communication module and an encryption module, wherein the PCIe interface comprises at least one high-speed serial computer expansion bus standard interface and at least oneuniversal serial bus interface. Electric energy is provided by the power supply, and the power supply management module distributes the electric energy to the mobile communication module and the encryption module; the universal serial bus concentrator converts one of the PCIe interfaces into two universal serial bus interfaces, namely a first universal serial bus interface and a second universalserial bus interface; the mobile communication module performs mobile communication based on the first universal serial bus interface, and the encryption module encrypts data of communication betweenthe second universal serial bus interface and a personal computer. In this way, the data encryption function and the mobile communication function can be achieved at the same time.

Description

technical field [0001] The present invention relates to the field of cryptographic technology, in particular to a cryptographic device and cryptographic equipment. Background technique [0002] A cryptographic device refers to a cryptographic product that has the functions of cryptographic operations, key management, physical random number generation, and equipment's own security protection measures. [0003] Cryptographic devices can be applied to 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, and CA (Certificate Authority, certificate center) systems. Related equipment, network cipher machine, security server, security terminal, security management center, key management equipment, etc. [0004] However, the existing cryptographic devices generally encrypt the data communicated between the PCIe ...

AI Technical Summary

Problems solved by technology

[0004] However, the existing cryptographic devices generally encrypt the data communicated between the PCIe (peripheral component interconnect express, high-speed serial computer expansion bus standard) interface and the PC (Personal Computer, personal computer), and generally do not have mobile communication functions and cannot be implemented. At the same time, it has data encryption function and mobile communication function
