Problems solved by technology
[0005] In view of the above problems, the object of the present invention is to propose a method and system for preventing relay attacks based on terminal sensor-based near-field wireless communication. The user is required to actively hold the mobile terminal to make a specific gesture, and dynamically recognize the user gesture through the data collected by the sensor event of the mobile terminal. After the recognition is successful, the subsequent business command interaction can be carried out, so as to solve the problem that the existing technology cannot be used on the mobile terminal side. The problem of blocking relay attacks in the authentication process

The invention provides a near field wireless communication relay attack prevention method based on a terminal sensor. The method comprises the following steps: establishing communication connection between a mobile terminal and a communication opposite terminal, and collecting sensor event data related to a gesture action of a user; performing behavior decision through sensor event analysis data; and judging whether operation is performed by the user himself or herself according to a decision result. The system comprises a terminal business APP, the terminal business APP is internally provided with an anti-relay attack service module, and the anti-relay attack service module is internally provided with a sensor event acquisition unit and an event data analysis and identity recognition unit; a user needs to actively hold a mobile terminal to make a specific gesture before near-field wireless communication service instruction interaction, then the gesture of the user is dynamically recognized through data collected by a sensor event of the mobile terminal, and subsequent service instruction interaction can be carried out after recognition succeeds. Therefore, relay attack behaviors can be defended and blocked from the source.
Description
technical field [0001] The present invention relates to the field of Internet of Things wireless technology and information security technology, in particular to a method and system for preventing relay attacks based on terminal sensor-based near-field wireless communication. Background technique [0002] In recent years, near-field wireless communication technologies such as Bluetooth and NFC of mobile terminals have been widely used. Typical applications include the use of Bluetooth and NFC modules of mobile terminals to realize services such as Bluetooth digital keys and NFC digital keys. Through Bluetooth / NFC digital key technology, users only need to A smart phone is required to complete various operations such as vehicle unlocking, vehicle information acquisition, and key sharing, which greatly facilitates user use and improves user experience. [0003] While the near-field wireless communication technology for mobile terminals represented by Bluetooth / NFC digital key ...
