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• An analogous document can be withdrawn• Example: driver license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• Establishment of a trust service maintaining a list of validand withdrawn digital copies Analogy: OCSP-Request Comparison with Blockchain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, …
