Hi all -

Next meeting will take place at BU (room 137, CS building).
Jeff Guarente will present the paper:

Secure Computation on the Web: Computing without Simultaneous Interaction 
Shai Halevi, Yehuda Lindell and Benny Pinkas, CRYPTO 2011
http://eprint.iacr.org/2011/157

Traditionally MPC requires all users to be online
simultaneously and for users to communicate directly amongst each
other. This model is unrealistic in many scenarios, such as when
unrelated clients connect to a server at different times without
coordination. This paper considers the model where clients connect to
a server once each, and one at a time, and all communication goes
through the server. It explores what attacks are inherent in this
model and what level of security can be achieved, and finds protocols
to achieve this security both in the general case and in specific
common cases.
