Ahto Buldas (born January 17, 1967) is an Estonian computer scientist who holds the Chair of Information Security at Tallinn University of Technology. He is the inventor of Keyless Signature Infrastructure, Co-Founder and Chief Scientist at Guardtime and Chair of the OpenKSI foundation.
Life and education[edit]
Buldas was born in Tallinn, capital of Estonia. After graduating from high-school, he was conscripted in to the Soviet Army where he spent 2 years as an artillery officer in Siberia. After being discharged, he started studies in Tallinn University of Technology, where he defended his MSc degree in 1993 and his PhD in 1999. He currently lives in Tallinn with his wife and four children.[1]
Career[edit]
Buldas was a leading contributor to the Estonian Digital Signature Act and ID-card from 1996 to 2002, currently the only national-level public-key infrastructure (PKI) which has achieved widespread adoption by a country's population for legally binding digital signatures.[2] He published his first timestamping related research in 1998 and has published over 30 academic papers on the subject. His experience of implementing a national level PKI led him to invent Keyless Signature Infrastructure,[3] a digital signature/timestamping system for electronic data that uses only hash-function based cryptography. By using hash-functions as the only cryptographic primitive the complexities of key management are eliminated and the system remains secure from quantum cryptographic attacks. His invention led to the founding of keyless signature technology company Guardtime in 2006. In 2002, Buldas received the Young Scientist Award by the Cultural Foundation of the President of the Republic of Estonia.[4]
Students[edit]
Buldas has been a supervisor for 15 MSc dissertations and 4 PhD theses. Buldas' student Margus Niitsoo is the youngest Estonian to attain a PhD in over five decades. In 2011, Niitsoo defended his theses "Black-box Oracle Separation Techniques with Applications in Time-stamping" while being 24 years, 4 months and 13 days old.[5][6] Currently, Niitsoo works as a lecturer at the University of Tartu.
