Both B2B bartering as well as bartering between individuals is
increasingly facilitated through online platforms. However, typically
these platforms lack automation and tend to neglect the privacy of their
users by leaking crucial information about trades. It is in this context
that we devise the first privacy-preserving protocol for automatically
determining an actual trade between multiple parties without involving a
trusted third party.
