Abstract

This paper describes an approach to apply digital signatures to MBSE models. This approach enables the digital signing of a portion of a model using a signer’s digital certificate, allows for the verification of the signed model content against the signature and indicates if information is altered from what the signer intended. This paper captures the technical challenges and lessons learned applying this approach as a prototype to an existing MBSE modeling tool.
