Researchers

Ahto Buldas

Ahto Buldas received his Ph.D in Exact Sciences from Tallinn University of Technology in 1998. He is working as a senior research researcher at Cybernetica, as well as Professor in Tallinn University of Technology. He has been Professor of Cryptography in the University of Tartu (2003–2010). His research interests include applied cryptography (hash functions, signature schemes, time-stamping) and risk analysis (game-theoretical attack-tree semantics). Current research interests: complexity-theoretic foundations of cryptology with applications to time-stamping, practical risk analysis of complex systems. Previously worked on time-stamping and PKI, algebraic graph theory, testing of Boolean circuits.

He has participated in the development of blockchain-based timestamping systems, and in the design of the SplitKey Authentication and Digital Signature Platform.
