  This contribution investigate the compatibility between the use of
dematerialised voting and Article 3 of the french Constitution, which
stipulates that 'voting must always be universal, equal and secret'. The IT
risk management of electronic voting is managed in a rational way like any
other risk management areas. We are therefore prepared to accept the use of a
non dematerialised technique to cover a significant, well-identified and
unavoidable risk. However, research has shown that a verifiable dematerialized
vote intrinsically loses its anonymity. In addition, a study of the history of
vulnerabilities shows that no terminal in recent years has been able to
guarantee the anonymity of its connection and that personal voting data has
always been potentially exposed. Electronic voting systems are therefore, to
the best of our knowledge, unable to provide the required constitutional
guarantee.
