Methodological problems with using Qualified Electronic Signature and Universal 2 Factor in web applications

Petar Dimitrov


This article aims to present some specific methodological features with using a Qualified Electronic Signature (QES) and Universal 2 Factor (U2F) technology for authentication in web applications. The legal basis, regulating using electronic signatures, is described. A comparison between the two technologies is made in the context of web applications and technical usage limitations for both technologies are described. Possible future developments of the U2F protocol in terms of usability and connectivity are discussed. Implementation of U2F authentication technology is proposed to be an additional layer of security in web applications, not only developed by the Bulgarian government, but also other web applications, requiring strong authentication.
