Mastering automotive network security: our core expertise

Security protocols: MACsec, (D)TLS, IPsec, Secured Global Time Synchronization

Protecting automotive networks from cyber threats is paramount to ensuring vehicle safety and data integrity. These networks, which oversee critical functions like steering and braking, are prime targets for hackers seeking unauthorized access or control. Robust security measures are essential in protecting from such attacks and maintaining passenger safety.

In today’s interconnected world, compromised networks can lead to accidents, data breaches, and privacy violations, highlighting the urgent need for enhanced network security in the automotive industry. Leveraging Elektrobit’s security protocols can fortify these defenses, providing manufacturers and consumers with peace of mind and confidence in vehicle safety.

Automotive network security

MACsec

MACsec is a security technology for Ethernet networks that provides Layer 2 authentication, encryption, and integrity checks to ensure secure communication between devices.

(D)TLS

(Data) Transport Layer Security (D/TLS) is a cryptographic protocol ensuring the data transmitted between end-nodes remains private and secure (including verifying the integrity of the data). (D)TLS is used in automotive networks to secure communications between various components, systems, and external services.

IPsec

Internet Protocol Security (IPsec), is a set of protocols and standards used to secure Internet Protocol (IP) communications. It provides a framework for securing network communication at the IP layer by authenticating and encrypting /decrypting each IP packet within a communication session.

IPsec enhances the security of communications between different components and systems within a vehicle, as well as for ensuring secure connections between vehicles and external networks.

SGTS

Secured Global Time Synchronization (SGTS) is an integrated security mechanism for Global Time Synchronization (GTS) to reduce the potential security risk in vehicles given its use cases in safety-critical, time-critical, and security-critical applications. Introduced in AUTOSAR R22-11 ensures the integrity and authenticity of the global time distributed inside the car across CAN, FlexRay, and Ethernet networks.
