Secure multiparty computation, MPC, is a field of cryptography, with the goal to let a set of participants give secret inputs to a computation, which they perform jointly. Examples of applications is votings where the voters don't want to tell anybody how they voted and auctions where a bid which don't win never becomes known to anyone except the bidder. VIFF is a framework which implements several protocols for MPC. This report gives a short introduction to MPC, VIFF and the protocols of VIFF. It also contributes with a small program, which with the help of VIFF, lets several participants anonymously answer a set of questions and gather statistics an all the answers.
