Digital Signatures

Determining voter eligibility and vote authenticity in an online election.

In online elections, voters don’t show up to polling stations with their IDs in hand. Because of this, the online voting system needs to determine a voter’s eligibility through different means. Digital signatures, which are cryptographic proofs that a piece of data, like an electronic ballot, was created by a specific user, are commonly used to determine voter eligibility. 

Digital signatures are based on asymmetric cryptography, meaning they contain a private key element only accessible to an individual voter, and a key that is publicly available. The private key is applied automatically when a voter hits “CAST,” identifying themselves as the creator of the ballot. Since this key is private, no one else will be able to impersonate the voter. When the voting server receives the ballot, it uses the publicly available key to “read” the voter’s identity and verify their eligibility.
