Cybernetica A State hold R&D company in Estonia Stock Capital: EUR 1. 15 M 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 Ph. Ds and 7 MScs)
ISec department: activities Security software development • Communications security • PKI • Time stamping Numerous scientific papers on time-stamping Close cooperation with universities
ISec department: some people Peeter Laud (1977) (Ph. D, 2002 “Computationally secure information flow”) Meelis Roos (1975) (MSc, 1999 “Integrated time-stamping and notarization”) Jan Willemson (1974 ) (Ph. D, 2002 “Size-efficient interval time stamps”)
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
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 Ph. D 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
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.
