IPMS researchers have developed additional protection against hacking of modern cars. The new function protects networked electronic systems in vehicles from cyber attacks.
Old technology further developed
The CAN (CAN bus) data transmission protocol, which is often used in vehicles, was developed in the 1980s. It impresses with its high level of robustness, flexibility and the associated cost savings. Since then, several variants of the serial bus system have been developed to meet the increasing demands. The latest CAN XL variant allows higher data transmission rates and also a scalable user data length.
The new standard (CiA613-1 and 2) is being developed by CAN in Automation to expand the CAN-XL protocol with safety functions (CANsec). These protect against unauthorized access and ensure the integrity and authenticity of the origin as well as the confidentiality of data in CAN-based networks. The CANsec Controller IP Core CAN-SEC developed by IPMS can be used directly between the host processor and a CAN-XL IP core.
Platform-independent usable
«The new IP core CAN-SEC builds the CANsec structure in the buffers of the CAN-XL core directly before sending or directly after receiving the frame. It can be used both with the CAN controller IP core from Fraunhofer IPMS and with IP cores from other manufacturers and, like all other IP cores from Fraunhofer IPMS, can be used in all FPGAs and foundry technologies, regardless of the platform,” explains IPMS -Researcher Marcus Pietzsch.
