The 2014 CTIC-IIIS Theory of Cryptography workshop, to be held October 20-24 in Beijing, China, is jointly organized by the Institute for Interdisciplinary Information Sciences at Tsinghua University and the Center for Theory of Interactive Computation at Aarhus University. The workshop’s format will consists of talks by attendees from Tsinghua, Aarhus, as well as by invited speakers from neighboring or international institutions. Topics will include multiparty computation, secure computation, information-theoretic cryptography, but also foundational issues and lattice-based cryptography. The purpose of the workshop is to foster academic exchange and to further research in these fields.
