Abstract
The article is an analysis of The Public Security Tests of Brazilian Electronic Voting System (TPS) in 2017 or TPS 2017. The Brazilian Superior Electoral Court (SEC), the national electoral authority, began to organize hacking challenges in 2009. These are a restricted event, including in research objects, where pre-approved external and independent researchers can examine the security mechanisms implemented within the system, find vulnerabilities, and provide suggestions for improvement. In 20 years of the Brazilian e-voting system, only four official securities tests, and all of them presented some failure or vulnerability. On this, three important scenarios in this research: a) the impact of the restrictions imposed on TPS 2017 in an election; b) the environment (laboratory) of TPS in the SEC; c) human fact in the security chain of the e-voting system. The originality of the work is related to the electoral observation of the three scenarios held at the SEC headquarters.
