July 9 2006, Venice, Italy

The 2nd Workshop on Formal and Computational Cryptography is co-located with ICALP 2006 and CSFW 2006 which will be held in Venice, Italy in July 2006.

Background, aim and scope

Since the 1980s, two approaches have been developed for analyzing security protocols. One of the approaches relies on a computational model that considers issues of complexity and probability. This approach captures a strong notion of security, guaranteed against all probabilistic polynomial-time attacks. However, proofs in this model are difficult and less successful for large, complex protocols. The other approach relies on a symbolic model of protocol executions in which cryptographic primitives are treated as black boxes. Since the seminal work of Dolev and Yao, it has been realized that this latter approach enables significantly simpler and often automated proofs of complex protocols. However, the guarantees that it offers with respect to a deployed protocol have been quite unclear.

The workshop focuses on the relation between the symbolic (Dolev-Yao) model and the computational (complexity-theoretic) model. Recent results have shown that in some cases the symbolic analysis is sound with respect to the computational model. A more direct approach which is also investigated considers symbolic proofs in the computational model. Papers proposing formal models sound for quantum security protocols are also relevant. The workshop seeks results in any of these areas.
