Digital signatures and electronic records

This paper gives an overview of the archival issues that relate to digitally signed documents. First, by way of introduction, the advanced digital signature is presented briefly. In the second part, a number of problems are discussed that present themselves when a digital signature is used as a proof of authenticity and integrity for digital documents in general. In particular, it is also being investigated whether it makes any sense for the archivist to digitally sign all electronic records under his or her management. Problems relating to the (medium) long-term archiving of digitally signed documents are dealt with in the third part. After an overview of the sticking points for long-term validation ("Archival issues'') a number of possible solutions are discussed ("Solutions for long-term archiving'').
