Dr. Mike Atallah
Dr. Atallah is a co-founder of Arxan Inc. and is a Distinguished Professor of Computer Science at Purdue University. He also serves as Chief Scientist for Arxan Defense Systems, Inc. Dr. Atallah joined the Computer Sciences Department at Purdue University immediately upon obtaining his Ph.D., and has been with Purdue since then. He was promoted to Associate Professor in 1986, to Full Professor in 1989, and to Distinguished Professor in 2004.
Dr. Atallah's current research interests are in information security. He received a Presidential Young Investigator Award from the National Science Foundation in 1985. A Fellow of both the ACM and IEEE, he has served on the editorial boards of many journals, and was selected to serve on the Program Committees of many top conferences and workshops. Dr. Atallah was Keynote and Invited Speaker at many national and international meetings, and a speaker in the Distinguished Colloquium Series of many top Computer Science Departments. He was selected in 1999 as one of the best teachers in the history of Purdue University and included in Purdue's Book of Great Teachers, a permanent wall display of Purdue's best teachers past and present.
Michael J. Jacobs
Mr. Jacobs is Senior Advisor for Cyber and National Security for SRA. Prior to Cyber and National Security, Mr. Jacobs was the Information Assurance (IA) Director at the NSA. Under his leadership, NSA began implementing an information assurance strategy to protect the Defense Information Infrastructure and, as appropriate, the National Information Infrastructure. He was responsible for overseeing the evolution of security products, services, and operations to ensure that the Federal Government's national security information was free-flowing, unobstructed and uncorrupted.
Mr. Jacobs had a long and distinguished career at the NSA, where he served in key management positions in both the Intelligence and IA mission areas. He served as the Deputy Associate Director for Operations, Military Support, where he was responsible for developing a single, coherent military support strategy for NSA. During his 38 years of NSA service, Mr. Jacobs was a leader in information systems security production and control, policy and doctrine, and customer relations. He has been recognized by the Department of Defense with the Distinguished Civilian Service Medal for his vision, dedication, and accomplishments; by the Director Central Intelligence with the Intelligence Community's Distinguished Service Award; and by NSA with the Exceptional Civilian Service Award. In addition, he has been awarded the National Intelligence Medal of Achievement and was twice awarded the Presidential Rank Award for Meritorious Achievement.
Mr. Jacobs received his BS in Business Administration from King's College, and completed the Senior Managers in Government Program at Harvard University's Kennedy School.Dr.
John T. (Tim) Korb
Dr. Korb is one of Arxan's three scientists. He joined the Purdue Computer Science faculty 1981 and now serves as Assistant Head for the department. Dr. Korb is responsible for the oversight and direction of the departmental computing facilities. He also serves on various campus-wide computing and networking committees, and represents the department at corporate and government events and activities. Recipient of the Outstanding Teacher in the School of Science award, he developed and taught a new undergraduate course in Programming Languages and recently taught the undergraduate Compiler course. He participates in a number of research projects. His research interests include programming languages, networking, databases, operating systems, and information security.
Before coming to Purdue, Dr. Korb worked at Xerox Corporation with their Palo Alto Advanced Systems Development group and was a visiting assistant professor at the University of Arizona. He is a member of the Association for Computing Machinery and Phi Beta Kappa.
Dr. Korb received his Ph.D. and MS from the University of Arizona and his BS from Arizona State University.
Dr. David M'Raihi
Dr. M'Raihi is Principal Scientist at Verisign. He recently authored the HOTP internet draft, endorsed by OATH (the initiative for Open AuTHentication) as a submission to the IETF for standardization of a one-time password algorithm enabling strong authentication for mobile users.
Dr. M'Raihi is a recognized expert who co-founded Gemplus' crypto labs in 1993 with Dr. Naccache, current head of Security Technologies Department for Gemplus worldwide. The labs have grown to nearly 60 software and hardware security experts. He was the lead architect and project manager for smart VISA Access, a secure solution designed for authentication and access control of banking applications. Dr. M'Raihi was appointed Director of Technology with Gemplus' Corporate Development in 2000. He led technical due diligences, identified and qualified investment opportunities for Gemplus' venture capital group, participated in divestiture operations and served as technical project leader for Joint Ventures and strategic Alliances.
Dr. M'Raihi has been involved in the design, development, audit and certification of secure schemes and software applications and systems for almost 15 years. He has authored and co-authored numerous papers and patents encompassing software protection, fast encryption algorithms, public-key authentication methods and digital signature techniques.
Dr. M'Raihi completed his Ph.D. in Cryptography under the supervision of Jacques Stern, Director of the Computer Science Department of the école Normale Supérieure (Paris, France).
Dr. John Rice
Dr. Rice is the founder of the ACM Transactions on Mathematical Software. He joined Purdue University in 1964 as Professor of Mathematics and Computer Science. For the past 30 years, he has been analyzing numerical methods and problem solving environments for scientific computing. Dr. Rice has created a general methodology for performance evaluation of mathematical software and developed software systems for solving partial differential equations: ELLPACK, Parallel ELLPACK and PDELab.
Dr. Rice is a fellow of the AAAS, a fellow of the ACM, a member of the National Academy of Engineering, and the former chair of the Computing Research Association. He has published 21 books; among recent ones are Mathematical Aspects of Scientific Software (1988), Expert Systems for Scientific Computing (1992), and Enabling Technologies for Computational Science (2000). Dr. Rice has also published about 300 scientific articles. The most recent ones are in the areas of computer security, agent based computing, mathematical software, problem solving environments, recommender systems and simulating gas turbines.
Dr. Rice received his Ph.D. in Mathematics at the California Institute of Technology.
