The invention discloses a WIFI-HID bidirectional unvarnished transmission method, device and system, and the method comprises the steps: receiving a to-be-transmitted command which comprises a transmission identifier which is used for distinguishing a transmission type, wherein the transmission type is reading or writing; acquiring a transmission identifier in the transmission command; determininga transmission type of the transmission command according to the transmission identifier; and reading or writing the to-be-transmitted data at a target terminal according to the transmission type. Inthe above method, the to-be-transmitted command comprises a transmission identifier, the transmission identifier is used for distinguishing transmission types, and the transmission type is reading orwriting; therefore, in the target terminal, for the data to be transmitted, according to different transmission types, reading operation and writing operation can be carried out, bidirectional transmission is realized, the problem of mismatching of WIFI and HID protocol rates is solved, and the problem that the feedback result of the transmission data at the corresponding terminal cannot be obtained due to unidirectional transmission is avoided.
Description
technical field [0001] The invention relates to the field of embedded technology, in particular to a WIFI-HID two-way transparent transmission method, device and system. Background technique [0002] With the development of the Internet of Things, security experts can perform remote communication and file transfer operations on HID (Human Interface Device) through WIFI. Typical devices that control HID attacks based on WIFI include WHID, USABUSE, WIFIDUCK and other devices. The main The structure includes WIFI module + Arduino module, connect the client to the WIFI module, connect the single-chip microcomputer connected to the server USB to the WIFI module, realize upload management and run scripts. [0003] However, the existing WHID and other devices do not have a main control chip module responsible for communication management. Most of the data transmission is unidirectional, and it is impossible to obtain the feedback results of the transmitted data on the corresponding...
