IPsec in automotive
IPsec, or Internet Protocol Security, comprises protocols and standards designed to secure network communication at the IP layer. It authenticates and encrypts each IP packet within a communication session, bolstering the security of automotive platforms. IPsec is pivotal for safeguarding communications between vehicle components and systems, as well as establishing secure connections between vehicles and external networks.
Secure communication between vehicle components
IPsec ensures secure data exchange between devices and networks, ensuring the integrity of safety-critical vehicle functions.
Remote diagnostics and software updates
OEMs rely on remote access to diagnose issues or deliver software updates. IPsec creates secure channels, protecting sensitive information and ensuring only authorized parties can access or modify vehicle systems.
Secured connected services
IPsec protects communication between telematics systems, external servers, and infotainment networks. Vehicle data such as location, performance, or streaming information is safeguarded against unauthorized access, ensuring secure connected services.
Resilience against network attacks
As vehicle connectivity rises, so does the risk of cyberattacks targeting automotive systems. IPsec is a key part of a robust security strategy, defending against unauthorized access, data breaches, and malicious code injections.
Key Features of IPsec
-
Secure IP-layer communication: IPsec enables authentication, confidentiality, and integrity for in-vehicle networks, using protocols like Internet Key Exchange v2 with pre-shared keys (PSK), authentication headers (acc. to RFC 4302), and extended sequence numbers (acc. to IETF RFC 4304) and starting and stopping IPsec.
-
Classic AUTOSAR-compliant module: EB tresos implementation of IPsec ensures secure communication via configurable modules compatible with Classic AUTOSAR middleware.
-
Configurable via EB tresos Studio: Developers can set security policies by port range, remote IP address, and protocol type, tailored to each ECU and communication requirement.
