CANsec IP Core

© Fraunhofer IPMS
Scheme: CANsec IP Core

The CiA 613-1 and -2 standards of CAN in Automation (CiA) extend the CAN XL protocol with security functions that protect the integrity, authenticity, and confidentiality of data in CAN-based networks.

The CANsec IP core can be used directly between the host processor and a CAN XL controller core. It builds up the CANsec structure in the buffers of the CAN-XL core directly before transmission or directly after reception of the frame. The CANsec IP core has internal registers that contain the information (identifier, key and mode) for the safe channels. The registers for up to 256 safe channels can be set by synthesis parameters. Therefore, the station equipped with the CANsec IP-Core can participate in up to 256 safe channels. The CANsec is compatible with the CAN XL Controller IP Core (CAN-CTRL) of Fraunhofer IPMS and can also be used independently or with other CAN XL solutions. 

Features

  • CANsec for CAN XL: compliant with CAN XL spec and add-on services (CiA 610-1, CiA 613-1/2)
  • NIST-aligned cryptography: AES, CMAC, AES-GCM
  • Up to 16 parameterizable cipher channels
  • Configurable secure channels up to 16
  • Single clock domain (from host interface)
  • Detailed error reporting and configurable interrupt sources
  • Reuses CAN XL controller TX/RX buffers; optional separate buffer for standalone operation
  • Compatible with multiple CAN XL IP cores

Scheme: LIN IP Core

The IPMS-LIN-IP core of the Fraunhofer IPMS supports the LIN specification 2.0, 2.1 or 2.2. The LIN (Local Interconnect Network) communication protocol for serial bus systems is mainly used in automotive applications, which require a lower bandwidth than CAN and is therefore comparatively cost-effective. The core is certified as ASIL-D-ready according to ISO 26262 for functional safety in automotive applications. The LIN IP design can be integrated into ASICs and FPGAs.

Features

  • LIN 2.2A compliant; backward compatible with LIN 1.3
  • Configurable for master or slave operation
  • Master: programmable data rate 1–20 kbit/s; Slave: automatic bit‑rate detection
  • 8-byte data buffer
  • 8-bit host controller interface
  • Fully synchronous, synthesizable RTL in VHDL or Verilog
