Legal Consequences

There is a widespread misconception among some lawyers, technologists and the public that the Estonian digital signature scheme provides reliable proof of the time when a document was digitally signed. In this article Tõnu Mets and Arnis Parsovs show that the legal requirement to establish the time of signing is not met in practice. The related legal requirement that the validation of the digital signature should confirm that the certificate was valid at the time of signing is also not met. The authors analyse the legal consequences of this, and discuss possible solutions for the issues that arise. They note that digital signature schemes used in other countries implementing Regulation (EU) No 910/2014 of the European Parliament and the Council of 23 July 2014 (eIDAS) are likely to share the problems discussed in this article.

Provably Secure

With the internet today available at the user’s beck, and call data or Information Security plays a vital role. Confidentiality, Integrity, Availability, and Non-repudiation are the pillars of security on which every application on the web is based on. With these basic requirements the users also need the security in low resource constrained environments making it more challenging for the security experts to design secured cryptographic algorithms. Digital Signatures play a pivotal role in Authentication. They help in verifying the integrity of the data being exchanged. Elliptical curves are the strongest contenders in Digital Signatures, and much research is being done to enhance the method in many ways. The paper briefs a secured and improved ECDSA Elliptical Curve Digital Signature Algorithm which is an improved and secured version of the Digital Signature Algorithm.
