Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless communication is used for autonomous vehicles to exchange information, then the autonomous vehicle can share and receive information (such as satellite navigation coordinates, acceleration information, live camera feed, traffic information, and speed) to execute various controls, but the communication may be compromised by hackers leading to information alteration and erroneous control execution
Solution Approach 1:
The system performs preliminary actions by generating cryptographic keys and encrypting data packets before transmission. The vehicle-mounted processor generates a key based on host vehicle information and encrypts the data packet with this key before sending it through communication channels, preventing hacker interference during transmission.
Solution Approach 2:
The terminal processor sends verification requests back to the vehicle-mounted processor to confirm key authenticity. After receiving encrypted data packets, the terminal processor extracts keys, verifies their authenticity, and controls connection statuses based on verification results, creating a feedback loop that ensures communication security.
2Reliability
If multiple communication channels are established for cross-verification, then communication security is enhanced through key verification, but the device complexity and processing requirements increase
Solution Approach 1:
The communication system is segmented into multiple independent communication channels, each capable of transmitting encrypted data packets. By dividing the communication infrastructure into separate channels (such as different wireless protocols or physical paths), the system can verify keys across multiple channels without requiring complete system redesign.
Solution Approach 2:
The encryption and verification mechanism serves multiple functions: it protects data integrity, authenticates communication partners, and enables secure key exchange across different communication channels. The same cryptographic approach is universally applied across all channels, simplifying the overall system architecture despite the multiple channels.
3Reliability
If data packets are encrypted and compressed before transmission, then communication security and efficiency are improved, but the processing time and computational resources required increase
Solution Approach 1:
The system performs encryption and compression as preliminary actions before data transmission. The vehicle-mounted processor encrypts the data packet with a generated key and compresses it before sending through communication channels, ensuring security and efficiency are built into the transmission process from the start.
Solution Approach 2:
The system creates encrypted copies of the original data packets for transmission across multiple communication channels. Instead of transmitting the original unencrypted data, the system generates and transmits encrypted copies, maintaining security while enabling efficient transmission across redundant channels for verification purposes.

AI summary
An autonomous vehicle communication safety system includes a vehicle-mounted communication device and a terminal communication device. At least two communication channels are established between the vehicle-mounted communication device and the terminal communication device. At least one vehicle-mounted processor of the vehicle-mounted communication device generates a key, stores the key in a data packet, encrypts and compresses the data packet, and outputs the data packet which has been encrypted and compressed through the at least two communication channels to at least one terminal processor of the terminal communication device. Once received, at least two encrypted and compressed data packets are decompressed and decrypted by the at least one terminal processor to obtain at least two keys to be verified. The least one terminal processor determines whether the keys to be verified are identical and consequently controls connection statuses of the at least two communication channels.
