Businesses could greatly benefit from globally exchanging such existing knowledge across organizations to optimize their processes. Unfortunately, confidentiality concerns and the lack of appropriate designs in existing data space frameworks—both in academia and industry—greatly impair respective actions in practice. To address this research gap, we propose MapXchange, our homomorphic encryption-based approach to combine technology parameters from different organizations into technology parameter maps while accounting for the confidentiality needs of involved businesses. Central to our design is that it allows for local modifications (updates) of these maps directly at the exchange platform. Moreover, data consumers can query them, without involving data providers, to eventually improve their setups. By evaluating a real-world use case in the domain of milling, we further underline MapXchange's performance, security, and utility for businesses. secure industrial collaboration; homomorphic encryption; data sharing; exchange platform; process planning; Internet of Production internet-of-production https://www.comsys.rwth-aachen.de/fileadmin/papers/2025/2025-pennekamp-mapxchange.pdf ACM Proceedings of the 40th ACM/SIGAPP Symposium on Applied Computing (SAC '25), March 31-April 4, 2025, Catania, Italy Catania, Italy ACM/SIGAPP Symposium on Applied Computing March 31-April 4, 2025 accepted 979-8-4007-0629-5/25/03 10.1145/3672608.3707734 1 JanPennekamp JosephLeisten PaulWeiler MarkusDahlmanns MarcelFey ChrstianBrecher SandraGeisler KlausWehrle
