V2X security credential system conformance testing equipment that flexibly responds to diverse and complex security protocols

S2X Tester is a solution that automatically evaluates interoperability/conformance between V2X OBU/RSU devices and the security credential system.

In an environment where a security credential system (SCMS) is applied, it provides users of V2X OBU/RSU devices with message signing, behavior verification, and error reports via a dedicated test station, enabling fast and easy SCMS testing.

V2X security credential system conformance, fuzzing testing, platform security testing,


  • V2X SCMS PKI server & security test system
  • World’s first support for IEEE 1609.2.1 standard testing
  • Efficient testing with an intuitive conformance evaluation process
