Workshop on Formal and Computational Cryptography (FCC 2008)

June 26, 2008, Carnegie Mellon University, Pittsburgh, PA, USA

affiliated with CSF'08

Background, aim and scope
-------------------------

Since the 1980s, two approaches have been developed for analyzing
security protocols. One of the approaches is based on a computational
model that considers issues of computational complexity and
probability. Messages are modeled as bitstrings and security
properties are defined in a strong form, in essence guaranteeing
security with high probability against all probabilistic
polynomial-time attacks. However, it is difficult to prove security of
large, complex protocols in this model. The other approach relies on a
symbolic model of protocol execution in which messages are modeled
using a term algebra and cryptographic primitives are treated as
perfect black-boxes, e.g. the only way to decrypt a ciphertext is to
use the corresponding decryption key. This abstraction enables
significantly simpler and often automated analysis of complex
protocols. Since this model places strong constraints on the attacker,
a fundamental question is whether such an analysis implies the strong
security properties defined in the computational model.

This workshop focuses on approaches that combine and relate symbolic
and computational protocol analysis. Over the last few years, there
has been a spate of research results in this area. One set of results
establish correspondence theorems between the two models, in effect
showing that for a certain class of protocols and properties, security
in the symbolic model implies security in the computational model. In
other work, researchers use language-based techniques such as process
calculi and protocol logics to reason directly about the computational
model. Several projects are investigating ways of mechanizing
computationally sound proofs of protocols. The workshop seeks results
in this area of computationally sound protocol analysis: foundations
and tools.

FCC'08 will be held in Carnegie Mellon University, Pittsburgh, PA, USA
on June 26, 2008, just after CSF'08 and during LICS'08. We invite
presentations of original results on the topics of the workshop. We
also encourage submissions that describe work in progress or that
further publicise interesting results published elsewhere. The main
goal of the workshop is to stimulate discussions and new
collaborations.
