What do we mean by secure voting?
- The term “secure voting” is generally thought to refer to cybersecurity and resistance to cyberattacks.
- However, cybersecurity is a general property of hardware/software that does not reflect the specific requirements of voting as a political process. The secret ballot is an established and indispensable requirement for voting.
- Secure voting systems must support privacy as well as integrity; these two requirements stand in opposition.
- In a system supporting privacy, no one, not even system administrators or other privileged observers can violate the secret ballot.
- In a system supporting end-to-end verifiability, voters can ensure that their vote was cast, recorded, and counted correctly.
- Cryptographically secure voting systems employ cryptographic technology to satisfy these two properties simultaneously. The gold standard are end-to-end verifiable voting systems.
- A secure voting system is an end-to-end verifiable voting system that also employs general computer security principles.
