Steve Olshansky, M.S.
Principal, LuminaGroup, LLC

Steve Olshansky has more than 20 years of business and technology experience. His focus has been on online trust technology & policy, security, privacy, digital identity, federated identity and access management (IAM), and enabling and enhancing collaboration and knowledge management within and between organizations. His experience includes developing technology strategies in support of business goals, Internet-based business applications, large-scale website and corresponding information architectures, knowledge management and electronic performance support systems (EPSSs), online communities and social networking, and online training and education.

He has focused his career on integrating and aligning technology with business processes — providing support to organizations large and small. He has worked extensively in the public and private sectors, improving efficiency and productivity. He has successfully managed large IT consulting and software development projects, as well as high-visibility web development efforts, from initial design through deployment.

He worked for the Internet Society from 2014 to 2023, and was Director of Trust Technology, Policy, & Strategy. He worked on and led a variety of initiatives and advocacy projects focused on security, privacy, trust, identity & access management (IAM), and the Internet of Things (IoT), among others. This included outreach and community engagement, and cultivation of productive relationships with numerous stakeholders across industry, government, and academia. The Internet Society is a global non-profit organization dedicated to promoting an open, globally connected, secure, and trustworthy internet for all. It plays a crucial role in shaping internet policies, standards, and protocols through its various initiatives and engagement with stakeholders. It was founded in 1992 by the “fathers of the Internet” and has since been at the forefront of efforts to ensure that the internet remains a global public resource. It is also the organizational home for the Internet Engineering Task Force (IETF), the premier standards development organization (SDO) for the Internet. 

From 2001-2014 he was with Internet2, the U.S. Research and Education (R&E) advanced networking consortium, serving as the consulting program manager for their next generation security and federated identity and access management (IAM) initiatives. In 2011 he joined the staff of Internet2 as Director, Federated Technologies. He was working on a variety of projects focused on the development and deployment of next-generation federated identity and access management infrastructure, aimed at reducing the friction inherent in secure cross-domain collaborations and resource access for both public and private sector institutions.

Much of the work at Internet2 was under the umbrella of the National Science Foundation (NSF) Middleware Initiative, and later the NSF Software Development for Cyberinfrastructure program. In addition, he was working on developing the potential of client certificates into real deployed intra- and inter-domain services (e.g. VPNs, authentication and multifactor authentication, signed documents, signed email). 

Steve holds a M.S. in Telecommunications from the University of Colorado at Boulder.  His experience also includes:

David Keaton, B.S.
Principal, Keaton Consulting

David Keaton has over 20 years of experience in computer and telecommunications technology, business, and standards. He is accomplished at leading geographically dispersed multidiscipline teams to deliver leading-edge products. He has developed parallel processor architectures that range from supercomputers to small embedded< systems; provided planning, analysis, and technical development of software, hardware, and network infrastructure; developed international standards; and provided training for diverse groups of technical and nontechnical people.

David is currently working on an extension to the C programming language to provide better mechanisms for preventing buffer overflows, a method typically used by hackers to exploit flaws in computer and router software. He has tested part of this work at Cisco with astonishingly good results. Soon, it is likely that all vendors will be required to certify their products to be free of buffer overflows, similar to the “Y2k-ready” campaign.

Another recent project involved creating a new scheme for selective encryption of MPEG-2 video at 10 times the efficiency of the Sony Passage system. This allows content producers to provide free distribution of videos that are either unusable or low quality until customers unlock them by purchasing a decryption key.

David continues to expand his areas of expertise and is conducting ongoing research in computer architecture and studies in new telecommunications developments such as software radio. He holds a BS in Computer Science from New Mexico Tech and is currently pursuing graduate studies in Telecommunications and Computer Science at the University of Colorado at Boulder. He serves on the international standardization committee for the C programming language (ISO/IEC JTC1/SC22/WG14) and on the Information Infrastructure Standards Panel (ANSI IISP).
