In-Vehicle Cybersecurity Protocols

MACsec, (D)TLS, IPsec and SGTS Safeguard Vehicle Security

Protecting in-vehicle networks from cyber threats is crucial for ensuring vehicle safety and data integrity. These networks, responsible for monitoring critical functions like steering and braking, are often primary targets for hackers attempting to gain unauthorized access or control. By implementing robust security mechanisms, you build an impenetrable defense for your in-vehicle systems.

MACsec

Media Access Control Security (MACsec) is a network security technology that provides Layer 2 (Data Link Layer) authentication, data encryption/decryption, and integrity checks for Ethernet. It ensures secure communication between network devices within the same Ethernet broadcast domain, suitable for end-node ECUs and compatible Ethernet switches.

(D)TLS

(Data) Transport Layer Security (D/TLS) is an encryption protocol that ensures data transmitted between end nodes remains private and secure (including verifying data integrity). (D)TLS is widely used in in-vehicle networks to protect communications between various components, systems, and external services from eavesdropping or tampering.

IPsec

Internet Protocol Security (IPsec) is a suite of protocols and standards used to protect IP communications. By authenticating and encrypting each IP packet at the IP layer, it provides a robust security framework for network communications, further enhancing the security between in-vehicle systems and the vehicle's connections to external networks.

SGTS

Secured Global Time Synchronization (SGTS) is an integrated security mechanism specifically designed for Global Time Synchronization (GTS). With the introduction of AUTOSAR R22-11, SGTS ensures the integrity and authenticity of time synchronization across CAN, FlexRay, and Ethernet networks within the vehicle, significantly reducing potential risks in safety-critical applications.
