Commitment scheme - Wikipedia
Webalso lets audit observers check (statistically) whether the commitments were accurate enough that the reported outcome is correct. Using appropriately de-signed cryptographic commitments protects voter privacy while still allowing the public to verify the audit. Effective verification, of course, depends upon the protocol being sound. A WebIn the standard definition of a commitment scheme, the sender commits to a message and immediately sends the commitment to the recipient interested in it. However the sender may not always know at the time of commitment who will become interested in it. incorporate health

WebAug 12, 2024 · An alternative cryptographic compiler, which avoids the polynomial-size support restriction by using a statistically-hiding commitment scheme (and an even more subtle analysis), is implicit in the work on constant-round zero-knowledge proofs for NP. Both of the above compilers yield zero-knowledge proof protocols in which the … WebMar 23, 2013 · Perfect hiding means, that a computationally unbound Alice COULD decomit any value: I.e. Pedersen commitments c = g x h r can be decommited to any value, if you know the discrete logarithm l o g g h. In your hash function you have no guarantee for this: for a fixed pair of commitment and K there might not be h ( N) to fulfill the computation.
