Withdraw and link from digitalcalibration certificates / twins
• An analogous document can be withdrawn• Example: driver license
• Retraction of cryptographically signed documents according toSigG, SigV and eIDAS is not intended
• Added value through the unique assignment of digital certificatesto an object (eg measuring device)
Problem
Approach
• Establishment of a trust service maintaining a list of validand withdrawn digital copies Analogy: OCSP-Request Comparison with Blockchain
• Construction of a chain of digital documents Idea: Merckle-Hashbaum Comparable to blockchain
• Legal evaluation Analogy: BeLab, AchiSig, …
