ABSTRACT: This paper deals with the
security of stock market transactions within financial markets, particularly
that of the West African Economic and Monetary Union (UEMOA). The
confidentiality and integrity of sensitive data in the stock market being
crucial, the implementation of robust systems which guarantee trust between the
different actors is essential. We therefore proposed, after analyzing the
limits of several security approaches in the literature, an architecture based
on blockchain technology making it possible to both identify and reduce the
vulnerabilities linked to the design, implementation work or the use of web
applications used for transactions. Our proposal makes it possible, thanks to
two-factor authentication via the Blockchain, to strengthen the security of
investors’ accounts and the automated recording of transactions in the
Blockchain while guaranteeing the integrity of stock market operations. It also
provides an application vulnerability report. To validate our approach, we
compared our results to those of three other security tools, at the level of
different metrics. Our approach achieved the best performance in each case.
