iden3/snarkjs#358 suggested a vulnerability of the groth16 verifier in the latest snarkjs (v0.6.11). A fix iden3/snarkjs#359 was proposed but has yet to be merged. The issue is not related to circom so it's safe to stay as is, as discussed with @curryrasul offline.
Upgrade snarkjs to the latest version as long as the fix is released.
Hi, I am researching the circuit in RLN and trying to understand how Shamir Secret Sharing works in RLN. However, I found that in the circuit, if the input x
(hashed message) keeps the same, and we could using the same x
to attack using the same messageId. To be more specifically, although we can detect that nullfier
repeated in the sent shares, yet we could not reveal the spammer's identitySecret
since the revealed (x, y)
are all the same.
I am just curious if there's a solution of this or maybe it is my misunderstanding with the protocol.
Thanks
