Bit commitment using pseudo-randomness
WebHowever there is a period, n, in a sequence of pseudo-random number generators prepared to work in a specific base with finite number of available bits to express the numbers (eg. binary). If this n wouldn't be big enough there would be serious problems, but don't worry, the computer scientists choose the seeds and other parameters of the ... WebDec 24, 2024 · If e.g. one had a pseudo-random number generator whose initial state was completely unpredictable, and which could be treated as a random oracle unless someone had access to about two billion consecutive bits, and a program used it to produce 10,000 bits, that would be fine if nobody else could get more numbers based upon the same …

WebDec 31, 2024 · A pseudorandom number generator, or PRNG, is any program, or function, which uses math to simulate randomness. It may also be called a DRNG (digital random number generator) or DRBG (deterministic random bit generator). The math can sometimes be complex, but in general, using a PRNG requires only two steps: Provide the PRNG … WebFeb 1, 2000 · Bit commitment using pseudo-randomness Proc. of Crypto'89, Lecture Notes in Computer Science, 435, Springer-Verlag, Berlin ( 1990) p. 128–136 Google Scholar Oka96 T.

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.

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 WebWe show how a pseudo-random generator can provide a bit commitment protocol.

WebMar 16, 2010 · Once we have n bits, we use a PRNG (Pseudo-Random Number Generator) to crank out as many bits as necessary. A PRNG is said to be cryptographically secure if, assuming that it operates over a wide enough unknown n -bit key, its output is computationally indistinguishable from uniformly random bits. flyefit ranelagh opening hoursWebNov 2, 1994 · LMR.
