Uri Blumenthal received M.S. degree in Applied Mathematics in Soviet Union in 1981. From 1981 to 1987 he worked at several Soviet research facilities as a Researcher and Systems Programmer. In addition following his military training Uri was commissioned as Lieutenant of Signal Corps. Uri was involved in work on Automated Control Systems for CAM, Computerized Management Systems for manufacturing plants, and kernel development work on OS/360, OS/370, RSX-11, RT-11, Unix v6 and other operating systems. From 1988 to 1989 he worked as a subcontractor at IBM East Fishkill, designing and implementing control system for measurement tools on semiconductor foundry manufacturing floor (System-38 and IBM PC).

In 1989 Uri was offered a position at IBM T. J. Watson Research Center to work on AIX development.  He implemented AIX/370 driver for Fiber Optics (FDDI) channel that was subsequently installed at CERN. From 1992 Uri gets involved in Network Management and Network Security issues, and begins participating at IETF (Internet Engineering Task Force). Uri contributed to SNMPv2 security design, and co-authored SNMPv3 User-based Security Model. Circa 1996 Uri co-founded and co-chaired an IRTF (Internet Research Task Force) Research Group on Services Management. Uri also designed and developed SNMPv3 platform-independent multi-version protocol stack that was tracking the evolving IETF SNMP standard. That implementation became IBM code base for SNMP support in all the corporate platforms. Besides Network Security and Network Management, Uri was involved in Cryptography research and published several papers on block ciphers and key schedules. In particular, he proposed a different key schedule for DES that increased the algorithm attack resistance to approximately 260, while maintaining verified and exhaustively analyzed DES encryption engine.

In 2000 Uri moved to Lucent / Bell Labs and joined Wireless Security and Fraud Prevention Group, where he worked on various security problems of cellular networks and was involved in 3GPP and 3GPP2 standards work. Uri drove Performance Evaluation project to analyze and predict performance impact of IPsec on wired and wireless Internet traffic. Also Uri had been working on solutions for base stations Provisioning on cellular network.

In 2004 Uri joined Intel labs to work on various security issues. He drove the effort to secure first release of Active Management Technology (iAMT’05), and did some work on security of communication protocols for AMT, provisioning for AMT, and run-time protection capabilities of computing hardware. Uri was involved in adding security functionality to Virtualization, particularly to Virtual Machine Monitor.

In 2007 Uri accepted the invitation from Bear Stearns to work on their security infrastructure. This illuminating position revealed where the money goes, and why requirements for better computer security are rarely forthcoming from the financial industry.

In the end of 2007 Uri joined MIT Lincoln Laboratory to work on securing communication protocols, computer applications, infrastructures, etc.

Uri’s most recent professional activities at Lincoln Laboratory have focused on Information Assurance. In particular he’s been delving into Identity Management and Access Control in complex configurations, and integration of NCES (Net-Centric Enterprise Services) into distributed application security architecture.
