Why is the Pedersen commitment computationally binding?
WebTheorem [GMW '87]: If a (t, ϵ) -bit commitment scheme exists, then all languages in NP have computational ZK proofs. Definition: (imprecise definition) A (t, ϵ) -bit commitment scheme is defined as follows: Commiter has a bit b ∈ {0, 1} , and sends commit(b) ∈ {0, 1} ∗ (a commitment to a bit b ). Commiter can open commitment as b ′ WebThe reader is assumed to have some basic knowledge about cryptography and mathematics, in particular public key cryptography and the algebra underlying the RSA and discrete log based public key systems. 2 Commitment Schemes 2.1 Introduction The notion of commitment is at the heart of almost any construction of modern cryptographic … the vine pmb
