An Improved Public Key Infrastructure (PKI)-Based Digital Signature Authentication Service for Higher Key Storage System

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.
