Fast, secure, and tamper-proof information sharing between NATO units on a need-to-know basis is crucial. Data quality and integrity are core needs but al-so resilience to failures and manipulations. The core idea of this paper is to use distributed ledger technology to allow a secure information exchange between Command and Control Information Systems of different NATO nations and non-NATO stakeholders such as non-NATO nations or mission observers. Moreover, the distributed ledger supports available NATO standards and formats for data exchange and storage.

This paper is included in the program of the Second Scientific Conference "Digital Transformation, Cyber Security and Resilience DIGILIENCE 2020 and will be published in the post-conference volume.
