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
