Faculty Candidate Talk: Anupam Datta, Stanford University, "Security
Analysis
of Network Protocols"
The design and analysis of network protocols that use cryptographic
primi-
tives is one of the most fundamental and challenging areas of
security
research. In this talk, I will present logical methods for protocol
analysis
that address two central problems in this area, significantly
advancing the
state-of-the-art. The first is "compositionality", where the
goal is to
develop methods for proving correctness of compound protocols by
combining
independent proofs of their components. Composition has proved to be
a dif-
ficult problem in security since a component may reveal
information that
does not affect its own security but may degrade the security of
some other
component in the system. The second research thrust is in
developing sym-
bolic methods for protocol analysis while being faithful to the
complexity-
theoretic model of modern cryptography. This work bridges and
benefits from
results in two research areas (logic and cryptography) which
have been
largely independent for the last two decades. Our
machine-checkable
axiomatic proofs do not involve probability and complexity.
However, the
soundness theorem guarantees that they carry the same meaning as
traditional
hand-proofs done by cryptographers. These methods have been
successfully
applied to a number of network security protocols including the IEEE
802.11i
wireless authentication protocol, IPSec's new key exchange protocol
IKEv2,
and SSL/TLS --- in some cases uncovering previously undiscovered
attacks.
Tool implementation efforts are also underway.
