 Furthermore, a sourcecode analysis of the DigiVote system in 2004 found several obvious errors with the security of the encryption keys, leaking of sensitive information, and lack of defensive secure coding practices.The voting system was also found to be vulnerable to a limited replay attack.Note that DigiVote is a trade name owned by German-based company Brähler ICS Konferenztecknik AG (also spelt Brahler and Braehler in non German speaking regions)  which manufactures battery powered radio audience response voting units for use in meetings and should not be confused with the ballot system used in Belgium.
