  1. Cybernetica Ahto Buldas Chief researcher

  2. Cybernetica • A State hold R&D company in Estonia • Stock Capital: EUR 1.15M • Founded 1997 as a derivative of the Institute of Cybernetics • Fields of actions: data security, systems development, marine navigation technology. • 23 persons in Information Security (ISec) department (5 PhDs and 7 MScs)

  3. ISec department: activities • Security software development • Communications security • PKI • Time stamping • Numerous scientific papers on time-stamping • Close cooperation with universities

  4. ISec department: some people • Peeter Laud (1977) (PhD, 2002 “Computationally secure information flow”) • Meelis Roos (1975) (MSc, 1999 “Integrated time-stamping and notarization”) • Jan Willemson (1974 ) (PhD, 2002 “Size-efficient interval time stamps”)

  5. Cybernetica’s R&D support for national projects • National ID card project • Electronic documents and digital signatures • Backbone for governmental information system (X-road) -- Provides unified access to all governmental databases Ensures confidentiality, integrity and traceability of exchanged data

  6. Time stamping and electronic notarization • Research on time-stamping started at 1997 • Most important paper: A.Buldas, P.Laud, H.Lipmaa, J.Willemson. “Time-stamping with binary linking schemes” -- CRYPTO’98. • More than 10 papers on time-stamping and PKI, 2 PhD theses • Developed -- a linkage-based time-stamping system, which provides • continuous validity of time stamps and electronic signatures • efficient off-line verification (previous schemes were too inefficient for practical use) • accountable service

  7. Main goals (in this project) • Technical roadmap for next three years on information security technologies -- September, 2003 • International data security workshop in Estonia, during 2004.
