Real-life Digital Signatures with Long-Term Validity
Tarvi Martens · 2004
The penetration of ID-cards in Estonia has reached well over 25%. Digital signatures are widely used in a variety of situations and treated equally to handwritten signatures by law. In this presentation we look into reality-proven infrastructure and end-user tools required to create digital signatures with long-term validity. The infrastructure is lightweight as compared to competing solutions, and is based on already existing industry standards and protocols. Use of OCSP responder as an electronic notary and secure logging system providing auditable security are explained. Some end-user tools that are based on the XAdES standard will be described.
