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.

Safety coaching interventions have become a common feature in the safety critical offshore working environments of the North Sea. Whilst the beneficial impact of coaching as an organizational tool has been evidenced, there remains a question specifically over the use of safety coaching and its impact on behavioural change and producing safe working practices. A series of 24 semi-structured interviews were conducted with three groups of experts in the offshore industry: safety coaches, offshore managers and HSE directors. Using a thematic analysis approach, several significant themes were identified across the three expert groups including connecting with and creating safety ownership in the individual, personal significance and humanisation, ingraining safety and assessing and measuring a safety coach's competence. Results suggest clear utility of safety coaching when applied by safety coaches with appropriate coach training and understanding of safety issues in an offshore environment. The current work has found that the use of safety coaching in the safety critical offshore oil and gas industry is a powerful tool in managing and promoting a culture of safety and care.
