Opis:
The authors of this article focus on the analysis of safety weaks of digital signature schemes used within e-Government service in condition of Slovak republic. Main part is orientated on the possibility of attacks on eID card with using RSA digital signature scheme what was in the last months very frequently medialized in Slovakia. In the practical part on the base of mathematically description is analysed possible weaks of RSA digital signature schemes especially complexity of factorization problems dependence of length of key is describe and compare with more effectiveness ECDSA scheme. On the base of studies the authors mentioned the recommendations for parameters selection of very often used digital signature schemes focus on access to safety-critical applications supported during process of digitalization of e-Government in Slovak republic.

Opis:
In a smart city environment, Intelligent Transportation System (ITS) enables the vehicle to generate and communicate messages for safety applications. There exists a challenge where the integrity of the message needs to be verified before passing it on to other vehicles. There should be a provision to motivate the honest vehicles who are reporting the true event messages. To achieve this, traffic regulations and event detections can be linked with blockchain technology. Any vehicle violating traffic rules will be issued with a penalty by executing the smart contract. In case any accident occurs, the vehicle nearby to the spot can immediately send the event message to Unmanned Aerial Vehicle (UAV). It will check for its credibility and proceed with rewards. The authenticity of the vehicle inside the smart city area is verified by registering itself with UAVs deployed near the city entrance. This is enabled to reduce the participation of unauthorized vehicles inside the city zone. The Secure Hash Algorithm (SHA256) and Elliptic Curve Digital Signature Algorithm (ECDSA-192) are used for communication. The result of computation time for certificate generation and vehicles involvement rate is presented.
