Presenter Peter Mate Erdosi Abstract To improve Hungarian e-governance capabilities by developing new IT services, the Hungarian Government has spent more than one hundred million Euros since 2010. As the base pillars of the Hungarian Digital State, a number of Controlled Electronic Administration Services (CEAS) have been implemented, one of them is the Hungarian Governmental Certificate Authority (GovCA). The usability of any digital system which can be linked to trust depends on the authenticity of stored and processed information. Using unauthentic information may result in fraudulent activities, which should be avoided also in the Public Administration. Electronic signature is a tool for signing and for the strong identification as specified by the new regulation. The European Union enacted the Regulation (EU) No. 910/2014 of the European Parliament and the Council called eIDAS in September of 2014. eIDAS contains comprehensive and obligatory rules for applying electronic identification and electronic signature in Europe. A given electronic signature has several attributes which are capable to uniquely identify it. This attributes can be ordered and structured by dimensions. In electronic public services, public servants are always able to decide whether an electronic signature is acceptable or has to be refused based on current legislation, regulations, implementing acts and national law. But for making a right decision, clear and consistent rules need to be exist. In this article I give a short introduction to eIDAS and analyse Hungarian national law using electronic signature dimensions in addition to identify existent and missing dimensions in the current legislation.
