Embodiment Construction

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0042] As the current USB interface devices are more and more widely used, the security requirements for data transmission through the USB interface are also getting higher and higher. For example, when used in special fields such as government security departments, the security requirements for data transmission through the USB interface will be higher. For another example, data transmission through the USB interface of a smart phone may cause security...

Abstract

The invention provides USB interface data protection method and apparatus, and device with USB interface. The device comprises a USB socket, a data transmission protection unit and a USB controller, wherein the data transmission protection unit is set between the USB socket and the USB controller; the USB socket is also used for connecting with a USB interface of external USB device; the USB socket is also used for performing data transmission with the USB controller; the data transmission protection unit is used for disconnecting a data transmission connection between the USB socket and the USB controller after being subjected to protection trigger. According to the scheme, the data transmission safety of the USB interface can be improved.

Description

technical field [0001] The invention relates to USB interface technology, in particular to a USB interface data protection method and device, and a device with a USB interface. Background technique [0002] At present, USB interfaces are widely used, and devices with USB interfaces are developing rapidly. When using the USB interface for data transmission, connect a device, such as a mobile phone, to another device, such as a USB socket of a computer, so that the two devices can transmit data through the USB interface. [0003] At present, when transmitting data through the USB interface, it is only necessary to connect the USB interfaces of two devices to perform the transmission, and there is no effective protection for the data transmission. If one of the devices, such as a mobile phone, includes an illegal program and steals data from another device such as a computer through the USB interface, data leakage will be caused, thereby reducing the security of data transmiss...
