It studies ways of securely storing, transmitting, and processing information. Understanding …
Pedersen commitment (with elliptic curves) - Findora
Commitment schemes have important applications in a number of cryptographic protocols including secure coin flipping, zero-knowledge proofs, and secure computation. A way to visualize a commitment scheme is to think of a sender as putting a message in a locked box, and giving the box to a receiver. See more A commitment scheme is a cryptographic primitive that allows one to commit to a chosen value (or chosen statement) while keeping it hidden to others, with the ability to reveal the committed value later. Commitment … See more Formal definitions of commitment schemes vary strongly in notation and in flavour. The first such flavour is whether the commitment scheme provides perfect or computational … See more Some commitment schemes permit a proof to be given of only a portion of the committed value. In these schemes, the secret value See more Physical unclonable functions (PUFs) rely on the use of a physical key with internal randomness, which is hard to clone or to emulate. Electronic, optical and other types of PUFs have … See more Coin flipping Suppose Alice and Bob want to resolve some dispute via coin flipping. If they are physically in the same place, a typical procedure might be: 1. Alice "calls" the coin flip 2. Bob flips the coin See more A commitment scheme can either be perfectly binding (it is impossible for Alice to alter her commitment after she has made it, even if she … See more It is an interesting question in quantum cryptography if unconditionally secure bit commitment protocols exist on the quantum level, that … See more WebDec 17, 2024 · Commitment scheme, such as zero-knowledge proofs [], which is executed between two parties (i.e., a sender and a receiver) through commitment and decommitment phases, is an essential component of the cryptographic scheme.In the commitment phase, the sender changes a message string into a commitment string and sends it to the receiver. dvd mighty mouse
