What is SecOC?

SecOC, or Secure Onboard Communication, refers to security mechanisms implemented in automotive electronic control units (ECUs) to protect communication within the vehicle network. It ensures data integrity, authentication, and confidentiality to prevent unauthorized access, manipulation, and eavesdropping on critical vehicle functions. Common use cases include secure software updates over-the-air (OTA), preventing unauthorized diagnostic access, and securing inter-ECU communication for safety-critical systems like braking and steering.
