Substitute `ChallengeGenerator` by the generic sponge #139

autquis · 2024-01-05T10:13:06Z

Description

In this PR, we are removing ChallengeGenerator and using only the sponge on which the PCS is generic. As a consequence, we are dropping the two strategies of generating challenges. However, as far as I noticed, the Univariate strategy was only used in a few tests and bench templates. So, I am not sure how big of an issue it is.

By deleting this for loop, the diff gets unnecessarily complicated. As soon as the PR gets a review, I will delete this for loop, and then please merge it.

Thanks for this PR! It looks pretty good overall. Since you're looking into this code, could you double check that the way we're deriving these challenges is not vulnerable to https://blog.openzeppelin.com/the-last-challenge-attack ?

Essentially, when we're doing batch verification, we need to ensure that we absorb all the proofs in the batch before we squeeze the opening_challenge.

autquis · 2024-01-09T11:15:01Z

Of course!

Currently, the sponge does not absorb anything. Even before this PR, the ChallengeGenerator was not absorbing anything. Is this a problem in Marlin and other schemes in the crate? (I am unfamiliar with their security analysis)
For Ligero, Brakedown, and Hyrax, I am not sure how we can absorb all the transcripts in batch_check. As the current implementation of batch_check calls check in a for loop, and the check method should absorb the transcript anyhow, I do not see an immediate solution to avoid double-absorbing. 🤔

Thanks!

True, there was only ever squeezes from a sponge...

Regarding the second point for IOP-based schemes, we anyway planned to improve the batch_check further down the line.

autquis · 2024-01-09T12:00:08Z

Thanks for the answer! Regarding batch_verify: Maybe the following rough idea helps. Instead of having check, we use two methods, check_transcript and check_proof. check_transcript has the proof and the challenges as arguments (i.e., no absorbing or squeezing). check_proof has the proof and the sponge as arguments, and needs to absorb or squeeze, then call check_transcript. batch_check does the same job as check_proof with some potential optimization for the case of many proofs.
I think it requires another discussion/issue/PR, though.

Pratyush · 2024-01-09T21:38:12Z

Ok seems like the blog post and what this PR aim to achieve are two different things; this PR talks about how to generate challenges for batch proving, and the blog post talks about batching pairings within a batch proof verification.

That is, the blog post talks about replacing this line with a squeeze from a sponge instead of a rng-derived challenge.

We should change that in a separate PR (it's not a soundness bug atm.)

Pratyush · 2024-01-09T21:42:31Z

Having resolved that confusion (sorry about that!), let's return our focus to the topic of this PR.

I think the reason why the current code is "sound" is that it assumes the sponge inside the challenge generator already absorbed the requisite commitments. For example, see the marlin code here: https://github.com/arkworks-rs/marlin/blob/026b73c20638f4f86cbae0946045934c865d5a30/src/lib.rs#L289. The absorption happens before we generate opening_challenge.

We can think about whether we want to change that or not; my inclination is that the answer is yes.

mmagician · 2024-01-09T22:46:31Z

That makes sense @Pratyush. In any case we can tackle this separately as this PR doesn't alter the old behavior (regarding what is assumed to be absorbed) right?

Pratyush

Yup, looks good. Can we file a follow-up issue?
