When generating certificates for the security conformance tests with the certificate generation tool, the certificates are already expired. I generated certificate CERT_IUT_A_AT today at 2019-02-01. When looking at the validityPeriod, it is set to start from 2018-01-01 and is valid for one year. When looking at the xml file used STF525_Its/data/v3/profiles/CERT_IUT_A_AT.xml, it looks like this: ... <validity> <restriction type="time" start="+0d" end="+365d"/> <restriction type="region"> <none/> </restriction> </validity> ...
