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, the capital of Estonia. After graduating from high school, he served two years in the Soviet Army as an artillery officer in Siberia. Upon discharge, he pursued studies at Tallinn University of Technology, earning his MSc in 1993 and PhD in 1999. He currently resides in Tallinn with his wife and four children.[1]
Career[edit]
Buldas was instrumental in developing the Estonian Digital Signature Act and ID-card from 1996 to 2002. He published his first timestamping research in 1998 and has since published over 30 papers. His experience led him to invent Keyless Signature Infrastructure, a digital signature and timestamping system using hash-function cryptography, eliminating key management complexities and ensuring security against quantum attacks. This invention led to the founding of Guardtime in 2006. In 2002, Buldas received the Young Scientist Award from the Cultural Foundation of the President of the Republic of Estonia.[2]
Students[edit]
Buldas supervised 15 MSc dissertations and 4 PhD theses. Notably, his student Margus Niitsoo became the youngest Estonian to attain a PhD in over five decades, defending his thesis "Black-box Oracle Separation Techniques with Applications in Time-stamping" at the age of 24. Niitsoo now works as a lecturer at the University of Tartu.[3]
