Cybernetica Ahto Buldas Chief researcher

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)

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

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”) ISec department: some people

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 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

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.
