Support & Training Downloads Careers Contact

Two engineers collaborate on testing automotive ECU security functions on a computer screen, focusing on secure communication, key management, and response to incorrect inputs. The image symbolizes ETAS' commitment to thorough and continuous security testing .

ESCRYPT Fuzz testing service targets the attack surface of connected vehicles. We use commercial and in-house fuzzers like our ESCRYPT CycurFUZZ for protocols like UDS and J1939. Fuzz testing reveals hidden bugs by exposing software to unexpected inputs. This helps you identify bugs before release, reduce vulnerabilities, and enhance software robustness for occupant safety and privacy.

Fuzz testing of embedded systems

The diagram shows fuzz testing for software robustness. Valid inputs lead to defined behavior, unexpected inputs cause undefined behavior, and invalid inputs are rejected. ETAS uses fuzzing to test reactions to random input, identify weaknesses and errors, including crashes in safety-critical ECUs. — Fuzz testing diagram illustrating how software handles valid, unexpected, and invalid inputs. Our experts at ETAS use this method to identify vulnerabilities, ensuring robust and secure vehicle systems.
