Functional Verification and Validation of Secure Controller Area Network (CAN) Communication 2022-01-0110

In agriculture industry, increasing use of Vehicle Internet of Things (IoT), telematics and emerging technologies are resulting in smarter machines with connected solutions. Inter and Intra Communication with vehicle to vehicle and inside vehicle - Electronic Control Unit (ECU) to ECU or ECU (Electronic Control Unit) to sensor, requirement for flow of data increased in-turn resulting in increased need for secure communication.

In this paper, we focus on functional verification and validation of secure Controller Area Network (CAN) for intra vehicular communication to establish confidentiality, integrity, authenticity, and freshness of data, supporting safety, advanced automation, protection of sensitive data and IP (Intellectual Property) protection. Network security algorithms and software security processes are the layers supporting to achieve our cause. Test environment setup with secured hardware and simulated models, test scenarios and test data are created to achieve the defined objective. For validation, we relied upon simulated models equipped with network security algorithms. Sharing of test results with stakeholders is the decisive step to get aligned with the test delivery agreed upon during test planning phase. Identification of threat sources, associated vulnerabilities, and its degree of impact analysis are critical aspects of our performed testing. Continuous and quality integration is also one of the aspects of test execution.

This paper also presents methodology used in software functional testing on security requirements. These ensure proper working of all the security functionalities as well-supports achieved software behaviors to ensure safety and security of a quality product. Also focuses on the best practices recommended by International Software Testing Qualifications Board Advanced Security (ISTQB) for risk assessment techniques, strategies, and security testing processes.
