Lessons From the Papal Conclave About Election Security

Hugh Pickens writes "The rules for papal elections are steeped in tradition. John Paul II last codified them in 1996, and Benedict XVI left the rules largely untouched. The 'Universi Dominici Gregis on the Vacancy of the Apostolic See and the Election of the Roman Pontiff' is surprisingly detailed. Now as the College of Cardinals prepares to elect a new pope, security people like Bruce Schneier wonder about the process. How does it work, and just how hard would it be to hack the vote? First, the system is entirely manual, making it immune to the sorts of technological attacks that make modern voting systems so risky. Second, the small group of voters — all of whom know each other — makes it impossible for an outsider to affect the voting in any way. The chapel is cleared and locked before voting. No one is going to dress up as a cardinal and sneak into the Sistine Chapel. In short, the voter verification process is about as good as you're ever going to find. A cardinal can't stuff ballots when he votes. Then the complicated paten-and-chalice ritual ensures that each cardinal votes once — his ballot is visible — and also keeps his hand out of the chalice holding the other votes. Ballots from previous votes are burned, which makes it harder to use one to stuff the ballot box. What are the lessons here? First, open systems conducted within a known group make voting fraud much harder. Every step of the election process is observed by everyone, and everyone knows everyone, which makes it harder for someone to get away with anything. Second, small and simple elections are easier to secure. This kind of process works to elect a pope or a club president, but quickly becomes unwieldy for a large-scale election. And third: When an election process is left to develop over the course of a couple of thousand years, you end up with something surprisingly good."

    Anyone who has had a group of friends vote on whether to eat Chinese or Italian knows that a group who all know each other can hold a secure vote immune from multiple votes or outsiders voting too. Its also obvious that this is not scalable beyond a group in which everyone does recognise everyone else

      It is astounding how many people don't understand the simple paper ballot voting system as it is still applied in many countries and hopefully will for a long time to come. It is based on the same principles as the papal vote, or actually the other way around. The most important aspect is that of public observability of all but the single secret aspect that exists in a proper election, and that single aspect is still completely observable by the person currently voting.

      This scales up to millions of voters by distributing the process such that partial results and their propagation to higher levels are observed by local competing groups, and not only isn't electronic voting helping, it's actually destroying the very core of this protocol: The observability.

      The problem with this and most similar schemes is it allows you to sell your vote.

      The thing that protects against vote selling is the difficulty of proving that you were faithful in your execution of the agreement. If I pay you 10$ to vote for the great flying spaghetti monster, I want to know you did in fact vote as instructed, and not for the lazy ravioli monster.

      The inability to verify a secret ballot is a feature, not a bug.

    Why focus on the voting mechanism? It's like testing the quality of a democracy by looking at the voting procedure in the house of commons. The weakness, as is always the case, is human accountability. This is just as true within a theocratic oligarchy as it is within a representative democracy.

    Anyone who thinks that powerful interests have no sway in the election of a pontiff is uneducated in history and blissfully naive.

    Considering that this voting process has evolved in the face of thousands of years of intrigue and backstabbing that makes even politicians look like choirboys, why is this a surprise? The evolutionary pressure was most certainly there.

    And of course this analysis overlooks the most reliable way of rigging an election, and one that is most certainly practiced here: hand-picking the electorate. Who appointed those cardinals in the first place, eh?

    Elections like this don't get manipulated during the ballot-casting, because they're not decided during the ballot-casting. Just like the decisions of a legislative body, the vote itself is merely the result of a ton of secret politics leading up to it.
