WebBit Commitment Using Pseudo-Random-Sequence Generators In document Foreword by Whitfield DiffiePrefaceAbout the AuthorChapter 1—Foundations (Page 137-140) This … In 1991 Moni Naor showed how to create a bit-commitment scheme from a cryptographically secure pseudorandom number generator. The construction is as follows. If G is pseudo-random generator such that G takes n bits to 3n bits, then if Alice wants to commit to a bit b: Bob selects a random 3n-bit … 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 $${\displaystyle X}$$ is a vector of many … 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 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 WebNaor, "Bit commitment using pseudo-randomness", J.
