> 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.
