The hidden voting scheme depends on the choice of symmetric encryption protocol: a poorly chosen protocol exposes the platform to a birthday problem attack in which malicious voters submit an encrypted key that can be decrypted in two different ways, letting them retroactively choose their vote.

This symmetric encryption protocol must be chosen carefully to avoid the birthday problem attack, where malicious voters could send an encrypted key that could be decrypted in two different ways.
