      The above commitment was from an email I sent Scytl asking if the OR Proof had ever been used as I was concerned that (like as happened before with the Shuffle Proof) that non-Swiss evoting code had also been released along side the Swiss code.

      Anyway, this OR Proof was missing a vital check in the verifier that resulted in it just not functioning at all. As I said before, this was completely dead code. But very broken dead code nevertheless.pic.twitter.com/RVfEgJpKAk

      Interestingly the presence of the OR Proof seems to violate the swiss evoting ordinance: "The documentation on the system and its operation must explain the relevance of the individual components of the source code for the security of electronic voting". https://www.admin.ch/opc/en/classified-compilation/20132343/index.html#a7b …

      Finally, the underlying proof framework that drives many of the ZKPs uses a non-collision resistant hash function. One of the key assumptions for the soundness of non-interactive ZKPs is that the hash function must act like a random oracle. It does not.pic.twitter.com/TpcYkCRBhU

      Many of these issues are not exploits in themselves, but are indicators of insufficient skill/attention/auditing in the design, implementation and checking of the system. None of these should have survived a competent audit. (How many audits has this system gone through again?)

      I wasn't asking a hypothetical (https://twitter.com/SarahJamieLewis/status/1106974216090341376 …) We have found critical issues in 2 major components of this system, and...*counts on fingers*...all of them if you count the many soundness issues in the other ZKP implementations. And +1 if you count the dead OR Proof.

      How many critical implementation flaws in a proprietary system are acceptable before we decide it is best to put it to one side and invest in truly open infrastructure instead? Asking for a friend.

      For the record, I asked Scytl if they would issue a public apology for their initial press release that stated that the initial criticisms of the their system were "based on misunderstandings related to the cryptographic mechanisms" They are still considering.

      It is a good time to remind everyone that the presence of Zero Knowledge Proofs in the swiss system was one of the major selling points. If anything should have been polished, audited, impenetrable it should have been the proof implementations. They were not.

      And so here we are. Let me predict the public responses: "A hacker would have to compromise several systems in order to get a chance at pulling this attack off, and it would be detectable" "The PIT worked and now the code is battle-hardened, what a success"

          None of this matters. The exploitability of this flaw, or the previous flaw don't really matter. What really matters in terms of the analysis of these systems is that this system was supposedly "state-of-the-art" and "ready for the challenge" It has been found wanting.pic.twitter.com/Oa5clfozc9

          If you are Swiss, and this all concerns you I'd suggest looking into your political options, contacting representatives, @eVoteMoratorium (https://wecollect.ch/de/campaign/evoting-moratorium/ …) among others. In my opinion, you should be asking serious questions of the entire development and funding process.

          If you are Australian, and this all concerns you, after all many of you just participated in an election on software that clearly shares code with the Swiss system. You should be pushing for transparency in your evoting systems:https://pursuit.unimelb.edu.au/articles/what-a-second-flaw-in-switzerland-s-svote-means-for-nsw-s-ivote …

          If you are in a country that is also adopting/has adopted evoting. Many of the point in the above linked article apply to you to. Without openness & transparency many of these issues, and possibilities for manipulation, would have gone undetected.

          I'm probably going to get some pushback again for "politicizing" this again. But: 1) This is software that determines national power distributions ffs 2) I run a non-profit that fights with & for marginalized communities. Everything is political, deal with it.

          Maybe time to break my self-imposed rule to not respond to your name-calling anymore. If #evoting dies in CH because of a hoax on TV, that would be silly. But if it dies because the company creating the code fails to follow minimal coding standards then that's a very good reason.
