Rump Session

A rump session will be held at the workshop and participants are invited to present their work there. We welcome both amusing and serious presentations at the rump session, and students are especially encouraged to present their work. Details on rump session submissions will be published closer to the event.

Call for Contributed Talks (closed)

TPMPC solicits contributed talks in the area of the theory and/or practice of secure multiparty computation. Talks can include papers published recently in top conferences, or work yet to be published. Areas of interest include

  • Theoretical foundations of multiparty computation: feasibility, assumptions, asymptotic efficiency, etc.
  • Efficient MPC protocols for general or specific tasks of interest
  • Implementations and applications of MPC

The TPMPC steering committee will select talks with the aim of constructing a balanced program that will be of interest to the audience.

Details regarding contributed talks and submissions:

  • Contributed talks will be 20-30 minutes.
  • The deadline for contributed talks is February 23 2019.
  • Please submit a short abstract (up to five pages, but preferably just one) of your proposed talk via the submission system: If your talk is an already published work, please include a link and information about where it was presented.
  • Notifications will be sent out no later than March 25 2019.

The program committee who will choose the talks is the TPMPC organization committee, consisting of Ivan Damgård, Yehuda Lindell, Jesper Buus Nielsen, Claudio Orlandi, Mike Rosulek, Thomas Schneider, and Nigel Smart.
