My research focuses on information security. I deal with virtually all areas of this area. The closest to my heart, however, is the subject of electronic signatures. Maybe it’s not a coincidence that the Hungarian Electronic Signature Association (HAES) elected me the member of board, as well as I could be a registered expert in electronic signatures. I dealt with more than one topic within the area of electronic signatures. They are as follows: Fundamentals of e-signatures Electronic archiving Interoperability of electronic signature products Practical implementation of electronic signatures
In the past years I made many presentations and writings in connection with electronic signature which are available in the Presentations section. Below I try to make a logical path for those who’re interested in this area.
Basics of electronic signature
This is the widest subject, generally every writing that deals with electronic signature describes the bases. From my own materials I can recommend the followings that contain what electronic signature is, how we can use it, the elements, etc.: The possibilities and limitations of the spreading of digital signature (in Hungarian) Possibilities and results of the usage of electronic signatures in the business (in Hungarian) Guide to the realization of IT security for local authorities
One of the most serious problem is the long term authenticity of digitally signed documents. I have many studies that deal with this and I also recommend the writings of Kollár Balázs. Authentic long-term archiving with electronic signature (in Hungarian) Electronic archiving system based on PKI (in Hungarian) Rules of digital archiving (in Hungarian) Electronic archiving system based on PKI (in Hungarian) Long term archiving with electronic signature (in Hungarian)
Interoperability of electronic signature creation applications
Besides archiving, the lack of interoperability of applications also causes serious problems because they can’t validate each other’s format. Melasz-Ready provides a solution for this which is a common standard developed by all significant e-signature application developers in Hungary. There are eight Hungarian applications that comply with this agreement. In my homepage all documents comply with the Melasz-Ready recommendation so testing of e-signature applications is possible. The following studies deal with the interoperability of electronic signature systems: Hungarian Electronic Public Administration Interoperability Framework (MEKIK) – Technical Standards Catalogue (in English) Developing interoperable e-government solutions in Hungary (in English) Digital signature: interoperable and secure applications (in Hungarian)
Practical implementations of electronic signature
I work for a long time to the spread of electronic signature widely. I see two solutions for that. We need applications in e-government or e-business where users can use the technology. There are only a few applications now but I’m optimistic. I have some writings about realized and envisioned applications. Development of a secure e-commerce system based on PKI (in Hungarian) Security analysis of the Hungarian e-government system (in Hungarian) Digital signature in enterprise environment (in Hungarian)
I continuously improve these links so visit my site from time to time. And of course write me if you have any questions in connection with electronic signatures.
