Bit commitment using pseudo-randomness
WebWe show how a pseudo-random generator can provide a bit commitment protocol. We also analyze the number of bits communicated when parties commit to many bits … WebThen you use this output as the next seed, and repeat the process as many times as needed. This is known as the middle-squares method and is just the first in a long line of …

Webpseudorandom permutations [11], statistically binding bit commitment [13], and many more. Such a pseudorandom generator can be obtained from an arbitrary one-way function, as shown in [6]. The given construction is not efficient enough to be used in practice, as it requires O(n8) bits of input randomness (for example, if

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 citess mahdiaWebBit commitment using pseudo-random synthesizer.
