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 … WebNov 11, 2024 · where xᵢ · λᵢ is a bit string, result of the concatenation between the bit string xᵢ and the single bit λᵢ. The H function generates a one bit longer sequence from the initial seed. By calling the H function l(k) times and taking just the last bit from each iteration, we have generated a sequence of l(k) bits. Obviously this function is G.. We are now able to …
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.
