Electronic voting System

Electronic voting

• Electronic voting is a term


encompassing several different types of
voting, embracing both electronic means
of casting a vote and electronic means of
counting votes
Continued….

• Electronic voting technology can include


•  punched cards
•  optical scan voting systems
• specialized voting kiosks
• self-contained Direct-recording electronic
(DRE) voting systems
Conti….

It can also involve transmission


of ballots and votes via
telephones, private computer
networks, or the Internet.

Cryptographic Voting Protocols

A simple protocol. 
Voter submit ballets with their voter ID.

Validator checks the voters off from the list


of registered voters

Validator submits only the balets to
the tallier.

Other protocols like

• The one and two agency protocols :

• Blind signature protocols:


conclusion

It is important that security and privacy


considerations be taken into account when
designing electronic voting system

electronic voting systems should be suitable


for a variety of polling applications

Electronic voting system is better than the


traditional voting systems
