Estonian Cryptography

Research

We do research in almost all subareas of cryptography, starting from very theoretical aspects (program analysis, exactness of reductions, and security models), going through cryptographic protocols (two-party computation, multi-party computation, zero-knowledge) and primitives (signature schemes and public-key encryption) and symmetric cryptography (differential and linear cryptanalysis, design of hash functions) to more practical areas (e-voting, a-auctions, implementations of multi-party computation, fast implementations of block ciphers, privacy-preserving data mining, anonymous communication, PKI and time-stamping).

Some of our research areas that have resulted in a large number of publications include:

Time-stamping and related areas (Ahto Buldas and others).

Papers at Crypto 1998, ACM CCS 2000, PKC 2000, PKC 2001, J of CS 2002, Asiacrypt 2004, PKC 2007, etc.

Privacy-preserving data mining and related areas like OT/CPIR, 2PC and MPC (Helger Lipmaa, Sven Laur, and others).

Papers at Asiacrypt 2003, PKC 2004, KDD 2006, ESORICS 2008, PKC 2010 (2 papers).

Efficient protocols for zero-knowledge, e-voting, e-auctions, etc (Helger Lipmaa, and others).

Papers at FC 2002, Asiacrypt 2003, FC 2004, ISAAC 2008.

Program analysis and computationally secure information flow (Peeter Laud, and others).

Papers at ESOP 2001, IEEE S&P 2004, ACM CCS 2005, ACM CCS 2006, TCS 2006, POPL 2008.

Private-key cryptography (Helger Lipmaa, Emilia Käsper, and others).

Papers at AES Conference 2000, FSE 2001, FSE 2004, CHES 2009.

Note that in all areas we have some well-known papers that were published in smaller conferences. In particular, some of our most cited papers were not published in ``good venues''.
