Cast-as-Intended Verifiability  (CaI)

Cast-as-Intended Verifiability 

Assuring voters that their digital ballots contain the right choices.

The ability for voters to verify that their vote has been encrypted and cast with the voting choices that they originally selected is known as cast-as-intended verifiability. This is one of the first verifications to be done, as it allows voters to reassure themselves that both their device and the encryption protocols are secure. If something does appear to be wrong, the voter can contact the appropriate officials and the problem can be remedied, usually before the end of the election.  

There are a few different methods through which cast-as-intended verifiability can be achieved, including having voters decrypt a copy of their cast ballot or allowing voters to encrypt and decrypt their ballot before casting it. These two methods allow a voter to verify that their ballot has been, or will be, encrypted properly without being altered in any way. Another method to achieve cast-as-intended verifiability involves sending a voter a list of unique codes after they cast their ballot. These codes correspond to specific voting options. Voters can then use these codes to verify that their ballot was cast with the correct ballot choices.
