Abstract

The digitization trend in the manufacturing industry is gaining pace and novel cloud based market places will play an important role in the transformation. However, existing market platforms are centrally organized and can not provide the required level of data privacy and trustworthiness needed for the manufacturing industry. In this work we study the security and privacy aspects for the case of a market platform for outsourcing in manufacturing. We show that the requirements identified together with relevant stakeholder are challenging and sometimes also contradicting on the first sight. To address this challenge we combined different cryptographic building blocks into a novel framework for more secure but transparent decentralized data markets. In particular the framework combines secure multiparty computation with zero-knowledge proof of knowledge methods and blockchain to enable flexible sealed-bid auctions which are also publicly verifiable. For evaluation a proof-of-concept was developed and benchmarking results show that the framework can efficiently address all requirements established.
