<div>The increased connectivity of vehicles expands the attack surface in-vehicle networks, enabling attackers to infiltrate through external interfaces and inject malicious traffic. These flows often contain anomalous semantic information, potentially leading misleading control instructions or erroneous decisions. While most semantic-based anomaly detection methods for networks focus on extracting context, they overlook interactions associations between multiple semantics, resulting...
