Timothy Hollebeek has 19 years of computer science experience, including eight years working on innovative security research funded by the Defense Advanced Research Projects Agency. He then moved on to architecting payment security systems, with an emphasis on encryption and key management, and wrote the first implementation of AES DUKPT, which is used to derive keys to protect credit card and PIN debit transactions. He remains heavily involved as DigiCert's primary representative in multiple industry standards bodies, including the CA/Browser Forum, IETF, and ANSI X9 striving for improved information security practices that work with real-world implementations. A mathematician by trade, Tim spends a lot of time considering the coming transition to post-quantum cryptography.
