In general, we quickly forget about boxes with paper archives, and there is not even a single sheet of paper on
the desktop. If a paper document is sent to the institution through regular mail, the artifact is immediately scanned
and digitized. In fact, it turned out to be quite the opposite. The more a company uses computers for digital
workflows, the more it documents and prints. Above all, every document must be authenticated. A document
without a signature is only a draft or an information note. To get the signature, the documents are printed and then
often scanned, and the original documents are kept on file. It is now clear that the (paperless) workflow cannot be
implemented without electronic digital signatures. In this study, an improved public key infrastructure-based Digital
Signature Authentication Service is proposed for higher key storage system. In this method, the CAs included in
the list provide certificate-based digital identifiers and time stamping services that comply with global regulations,
such as the eIDAS standard. Electronic digital signatures are already supported for most popular office document
formats. Timestamps are supported, including multi-person document signatures.
