Problems solved by technology

This pairing mode can easily lead to attackers attacking nodes through devices that can only be connected in (just work) mode, or attackers to attack nodes that can only use direct working mode, which has a very high impact on user privacy and vehicle safety. Threat, especially for in-vehicle communication systems, this situation is likely to cause the vehicle to be untrusted, causing the vehicle to communicate with an attacker whose identity is not credible, and even endanger the personal safety of the driver and passengers in severe cases

Embodiment approach 1

[0418] Embodiment 1: The pairing response message includes an input / output capability IOC field, and the IOC field includes information for indicating whether the second node has the PSK pairing capability. For example, when the value of the IOC field in the pairing response message is 0x05, it may indicate that the second node has the PSK pairing capability; correspondingly, when the value of the IOC field is other values, it may indicate that the first node does not have the PSK pairing capability, Therefore, it can be indicated that the first node cannot perform pairing based on PSK. Further, when the value of the IOC field is other values, it may specifically indicate the input and output capability of the second node. For example, the value of the IOC field is 0x01, which may indicate that the input and output capability of the second node is DisplayOnly.

Embodiment approach 2

[0419] Embodiment 2: The pairing response message includes an IOC field, and some bits of the IOC field include the PSK capability value of the second node, and the PSK capability value of the second node is used to indicate whether the second node has PSK pairing capability. For example, the 2 bits in the IOC field contain the PSK capability value of the first node, and the PSK capability value "01" indicates that the second node has PSK pairing capability or there is a first PSK shared with the first node, so it can Support pairing based on PSK. Optionally, if the PSK capability value is "00", it may indicate that the second node does not have PSK pairing capability information or that there is no first PSK shared with the first node, and PSK-based pairing is not supported at this time. Pairing via another pairing mode is required.

[0420] It can be understood that in the embodiment of the present application, the part of bits is taken as 2 bits as an example, and in speci...

Embodiment approach 3

[0422] Embodiment 3: The pairing response message includes a PSK capability field, and the PSK capability field includes a PSK capability value of the second node, and the PSK capability value of the second node is used to indicate whether the second node has PSK pairing capability. For example, a PSK capability value of 0x01 indicates that the second node has a PSK pairing capability or that there is a first PSK shared with the first node, and therefore, PSK-based pairing can be supported. Optionally, if the PSK capability value is 0x00, it can indicate that the second node does not have PSK pairing capability information or that there is no first PSK shared with the first node. At this time, PSK-based pairing is not supported, and it needs to pass pairing in other ways.

[0423] Optionally, the pairing response message also includes an IOC field, which can be used to indicate the input and output capabilities of the second node, so that the first node can determine the pairi...

Abstract

Embodiments of the present application provide an association method and device, which are applied to nodes supporting Bluetooth communication. The method includes: receiving a pairing request message from a first node, where the pairing request message includes information indicating whether the first node has a pre-shared key PSK pairing capability; Having the information of PSK pairing capability, sending a pairing response message to the first node, where the pairing response message is used to indicate pairing using the shared first PSK; and authenticating the first node according to the first PSK. By adopting the embodiment of the present application, the security of the node pairing process can be improved, and the nodes can be prevented from connecting to untrusted devices. This solution can further be used to improve the capabilities of autonomous driving or advanced driver assistance system ADAS, and can be applied to the Internet of Vehicles, such as vehicle outreach V2X, vehicle-to-vehicle communication long-term evolution technology LTE-V, vehicle-vehicle V2V, etc.

Description

technical field [0001] The present invention relates to the fields of communication technology and networked vehicle technology, in particular to a Bluetooth node pairing method and related devices, such as Bluetooth communication in the cockpit domain. Background technique [0002] Today, with the rapid development of information technology, communication technology has penetrated into people's lives. While enjoying the convenience of communication, we also face the threat of security breaches and privacy leaks. Taking smart cars as an example, with the wide application of vehicle communication, wireless communication technology can be used to communicate between cars and other devices, and between various components in the car. Generally speaking, before two nodes perform wireless communication, an association relationship needs to be established between the two nodes, and this process of establishing an association relationship can also be called a node pairing process. ...
