Abstract

The invention provides an encryption Hub device supporting multiple UFS equipment. The encryption Hub device comprises a controller, a Flash memory module, an encryption and decryption module and a USB-KEY module which together form a Hub encryption and decryption module, wherein the Hub encryption and decryption module is connected with a PCIE transmission module PCIE Device and connected with an external PC host supporting PCIE through the PCIE transmission module PCIE Device; the Hub encryption and decryption module is connected with a Port-Controller through a data bus; a plurality of M-PHY expansion interfaces are arranged on the Port-Controller; the PC host encrypts data to be written in through the Hub encryption and decryption module and then writes the encrypted data into UFS equipment connected to the M-PHY expansion interfaces; the Hub encryption and decryption module decrypts the encrypted data on the UFS equipment and then transmits the decrypted data to the PC host. The encryption Hub device based on the M-PHY interface realizes expansion of the M-PHY interfaces, can improve the security of UFS data transmission, guarantees the safety of UFS data, meanwhile, has the characteristic of high USB-KEY compatibility, can meet the demands of special users and is greatly improved in flexibility.

Description

technical field [0001] The invention relates to the field of data transmission security, in particular to an encryption Hub device supporting multiple UFS devices. Background technique [0002] In the era of rapid development of electronic information, people pay more and more attention to information security. Information security itself covers a wide range, ranging from national military and political secrets to small corporate secrets and personal information. Any security breach may cause information leakage. There are many ways to transmit information. During the process of storing, processing and exchanging information, there are possibilities of leaking or interception, eavesdropping, tampering and forgery. A single confidentiality measure is usually difficult to guarantee the security of communication and information. It is necessary to comprehensively apply various levels of confidentiality measures to realize the protection of the three links of source, signal and ...
