Bit commitment scheme
WebBit commitment is an important cryptographic primitive; it can be viewed as an electronic realiza-tion of a locked box [Gol01]. Roughly speaking, a bit commitment scheme is a two-stage (consisting of a commit stage and a reveal stage) interactive protocol between a sender and a receiver, pro-viding two security guarantees: hiding and binding.

WebJan 2, 1994 · It is shown that the existence of a statistically hiding bit commitment scheme with noninteractive opening and public verifiability implies theexistence of fail-stop signatures, and that such signatures can now be based on any one-way permutation. We show that the existence of a statistically hiding bit commitment scheme with … WebDefinition 1. A Bit Commitment scheme is statistically concealing if only a negligible amount of informa-tion on the committed bit can leak to the verifier before the unveiling stage. Definition 2.

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 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 has unbounded computational … See more It is an interesting question in quantum cryptography if unconditionally secure bit commitment protocols exist on the quantum level, that is, protocols which are (at least … See more Coin flipping Suppose Alice and Bob want to resolve some dispute via coin flipping.
