AI Technical Summary
In existing intelligent connected vehicle communication, fixed key algorithms and negotiated keys are at risk of being cracked, which increases the possibility of data leakage. Existing technologies have not been able to effectively solve the problem of dynamically generating shared keys.
By setting and storing key information, including data impact level, communication rate requirements, key security tolerance, vehicle-side capability level, key rated security strength, key allocation strategy, and data communication threshold, shared keys are dynamically allocated. During communication sessions, negotiated keys are switched based on data communication time and quantity thresholds. Intelligent agents are used to train and calculate key strength requirements, and key management and communication are performed using modules on the cloud server and vehicle side.
It improves the security of data communication, reduces the risk of data leakage, and enhances the reliability and security of communication.
