Problems solved by technology
However, the traditional CAN (Controller Area Network, controller area network) bus cannot meet the needs of intelligent networked vehicles due to slow transmission speed and other reasons.
[0003] The above-mentioned CAN bus has security deficiencies. In recent years, news reports about hacking cars have often appeared in the newspapers. The main reason is that the existing vehicle bus lacks security design, so that any user and program can Inject illegal information on the bus, and can sniff information of interest on the bus

The invention relates to a message access method and system. The method comprises the following steps: an authentication client sends an authentication request to a bus access authentication server; the bus access authentication server performs identity authentication according to the authentication request; if the authentication is passed, the bus access authentication server sends authentication passing information to the authentication client; the bus access authentication server sends a request message or an identity confirmation message to a message bus system according to the identity information; and the message bus system receives the request message or the identity confirmation message, and performs resource allocation and multicast address allocation for the authentication client, or updates a multicast security policy for the authentication client. The authentication process is triggered when the authentication client needs to publish the theme message or need to receive the multicast message, so that malicious information is prevented from being injected into the bus from the source, information eavesdropping on the bus is avoided, and the security of in-vehicle message transmission is remarkably improved.
Description
technical field [0001] The present disclosure relates to the field of communication security, in particular to a message access method and system. Background technique [0002] The research and development of intelligent connected vehicles is the current focus of the industry. The emergence of intelligent networked vehicles has made the on-board electronic systems increasingly complex. Cars with advanced driver assistance systems (ADAS, Advanced Driver Assistance System), automatic driving, infotainment and other functions are equipped with more and more electronic devices, such as cameras, Millimeter wave radar, lidar, etc. A large amount of data generated by these devices needs to be transmitted to the processing unit in the vehicle in a timely manner, which places high demands on the bus bandwidth. However, the traditional CAN (Controller Area Network, Controller Area Network) bus cannot meet the needs of intelligent networked vehicles due to slow transmission speed and...
