Embodiment approach

[0039] As an implementation, when the logic device inside the signal sending module 31 is used to realize the USB signal shielding function, the signal sending module 31 is used to obtain the signal identifier corresponding to the USB signal when receiving the USB signal sent by the USB host device 20, And when the signal identifier corresponding to the USB signal satisfies the preset shielding condition pre-stored by the signal sending module 31 or the signal receiving module 32 , shield the USB signal so that it cannot be transmitted to the USB slave device 50 .

[0040] As another embodiment, when the logic device inside the signal receiving module 32 is used to realize the USB signal shielding function, the signal receiving module 32 is used to obtain the signal identification corresponding to the USB signal when receiving the USB signal sent by the USB host device 20. , and when the signal identifier corresponding to the USB signal satisfies the preset shielding condition ...

Abstract

The embodiment of the present invention relates to the field of information security technology, and provides a signal transmission management method and system, the method comprising: when the transmission device receives the USB signal sent by the USB master device, obtains the signal identifier corresponding to the USB signal; when the USB signal When the corresponding signal identifier satisfies the preset shielding condition, the transmission device shields the USB signal so that it cannot be transmitted to the target USB slave device. Compared with the prior art, the embodiment of the present invention can effectively prevent the USB slave device from copying data from the USB master device and prevent the use of prohibited devices, thereby ensuring the information security in the USB master device.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of information security, and in particular, to a signal transmission management method and system. Background technique [0002] USB (Universal Serial Bus, Universal Serial Bus) is a high-speed serial communication interface specification, which is widely used in electronic products such as computers, printers, mobile phones, U disks, and tablet computers. At present, the USB device or USB signal transmission type supported by the USB host device (for example, a computer) can be set through the administrator authority, that is, as long as you have the administrator authority, you can freely set the supported USB device or USB signal transmission type , so that it is easy to copy confidential data from the USB host device, or use a prohibited device, resulting in that the information security in the USB host device cannot be guaranteed. Contents of the invention [0003] The purpose o...
