Siebren Lepstra is currently working as Enterprise Architect PKI and chip technology at the Judicial Information Service as part of the Dutch Ministry of Justice and Security. For the last ten years Siebren is involved in the field of PKI, chip technology, applied cryptography and, more recently, quantum technology. Quantum technology is evolving fast and poses significant risks to anything involving cryptography, including the travel documents we use every day.
For his master thesis, theory and field practice have been combined to take the first steps into adding post quantum cryptography into travel documents, specifically for passive authentication: the most important protocol for electronic travel documents used worldwide.
