Short Bio: Dr Thomas Hardjono is currently the CTO of Connection Science and Technical Director of the MIT Trust-Data Consortium, located at MIT in Cambridge, MA.  For several years prior to this he was the Executive Director of the MIT Kerberos Consortium, helping make the Kerberos protocol to become the most ubiquitously deployed authentication protocol in world today. Over the past two decades Thomas he has held various industry technical leadership roles, including Distinguished Engineer at Bay Networks, Principal Scientist at VeriSign PKI, and CTO roles at several start-ups.  He has been at the forefront of several industry initiatives around applied cryptography, identity, trust and cybersecurity.

Aside from various open source software projects, he has held leadership roles in various standards-defining organizations (as specifications editor; working group chair; board member):  Trusted Computing Group (cybersecurity of systems); Open Music Initiative (smart contracts for music licensing); Internet Engineering Task Force (public-key certificates, multicast authentication & Kerberos); Kantara Initiative (decentralized identity management); Open Interconnect Forum (IoT security); OASIS Security Services Task Force (Security Assertions Mark-Up Language); IEEE 802 TGi (for WiFi Security).
