The protocol combines encrypted ballots so that only the totals for each candidate are revealed, not the individual voters' choices. All encrypted ballots can be combined using a mathematical protocol that preserves the sum without decrypting the individual components.
Conditions: All ballots are encrypted before submission.; Aggregation is performed on encrypted data.; Only final totals are revealed.

The envelope is used as a concrete metaphor for cryptographic encryption of the ballot values. Putting the vote inside the envelope actually means encrypting them using a specific type of scheme, hiding the ballot values from public view while preserving later aggregation properties.
Conditions: The ballot values are hidden from public view.; Encryption is assumed to preserve later aggregation properties.; The specific cryptosystem is not named in this clip.
