Abstract [eng] Electronic remote voting is a challenging and intriguing computer security engineering task. The crucial impact that compromised elections have on democracy and voters’ trust differs from any other internet activity. Due to the importance of the election outcome, highly skilled adversaries might attack users with low computer literacy. Lithuania has been grooming the idea of e-voting since 2016, however, real proposals did not satisfy the constitutional requirements and have been rejected. Due to the drastically increased remote activity in recent years, another remote electronic voting feasibility study was commissioned by the Lithuanian Central Election Commission. In light of this context, this thesis defines the critical aspects of an electronic voting system and the feasibility of its security requirements. As a methodology, the security analysis of the blockchain and linkable ring signature-based electronic voting framework Chirotonia developed at the University of Naples Federico II is performed. The analysis is based on Bayesian attack graphs which are automatically generated based on the obtained knowledge.
