About aMACI

aMACI, which stands for anonymous Minimal Anti-Collusion Infrastructure, utilizes rerandomizable encryption to ensure voter anonymity. This system allows participants to deactivate their existing keys at any time and generate new ones, which the operator cannot link to any previous keys. Consequently, when a new key is used for voting, it remains completely anonymous.
