Innovation Solution
A vehicle security communication method and device that utilizes a security chip to decrypt encrypted control data from the network system before transmitting it to the vehicle body system, ensuring only legitimate commands are executed, thereby preventing unauthorized control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vehicle multimedia is connected to networks to provide entertainment and multimedia services, then user experience and functionality are improved, but security risks increase due to potential malicious invasions and unauthorized control
Solution Approach 1:
The patent introduces a security chip as an intermediary component between the network system and vehicle body control systems. This security chip acts as a mediator that verifies and authorizes control instructions before they reach the vehicle body system, thus enabling network connectivity while preventing unauthorized access and malicious control attempts
2Extent of automation
If vehicle multimedia is equipped with 4G and WIFI modules to enable remote control and cloud services, then remote functionality is improved, but vulnerability to malicious programs increases
Solution Approach 1:
The patent implements preliminary security verification through the security chip before control instructions are executed. The security chip pre-authores incoming control instructions from the network, blocking malicious programs before they can affect vehicle operations, thus enabling remote control while preventing harmful invasions
3Ease of operation
If vehicle multimedia transmits control instructions to vehicle body system to enable remote operation, then operational capability is improved, but risk of false instruction transmission increases
Solution Approach 1:
The security chip serves as an intermediary that verifies the authenticity of control instructions before transmission to the vehicle body system. It checks whether incoming instructions are legitimate and authorized, thus enabling ease of remote operation while ensuring instruction authenticity and preventing false control commands
Data Source
AI summary
The present application discloses a method and a device for vehicle security communication, a vehicle multimedia system, and a vehicle. The method applied to a security chip comprises: receiving a control instruction from a network system when the network system is connected, wherein the control instruction includes encrypted control data; decrypting the encrypted control data in the control instruction; obtaining the decrypted control data when the decryption is successful; and transmitting the decrypted control data to the vehicle body system to make the vehicle body system control the vehicle to perform a target operation according to the decrypted control data.
