Commonly used security methods for authentication and encryption/decryption on the Internet cannot be easily applied to CAN/CANopen. ESAcademy’s solution is CANcrypt, an ingenious combination of scalable security features for CAN.
The in-depth description of CANcrypt is available as book: “Implementing scalable CAN security with CANcrypt, Authentication and encryption for CANopen, J1939 and other Controller Area Network or CAN FD protocols”
Update concerning the EU Cybersecurity Act (CSA) and the EU Cyber Resilience Act (CRA):
While the current CANcrypt can be used to achieve the basic security requirements of these acts, it can not achieve higher security levels. We are currently working together with the University Offenburg and the CiA Special Interest Group (SIG) Higher-Layer Protcol (HLP) Security on solutions suitable to meet the most stringent security demands.
