✦ Synopsis

Security research has long focused on protecting against outside attackers. This was augmented with protection against insider threats, but recently networked business is emerging. With it a new threat is emerging: security against the business partner.

A possible solution is secure multi-party computation (SMC) and we give examples of its usefulness. We show with the example of supply chain optimization that only SMC provides the necessary security guarantees.

A major challenge of SMC is its practical realization. We give a detailed study and analysis of multi-party permutation and show the relations of the different theoretical complexities in this case.

The paper concludes with a comparison of service-oriented architectures and SMC. We show several architectural differences that need to be overcome.
