WebSep 27, 2024 · Cryptographic commitment schemes allow one to commit to some secret value without having to reveal it (at the time of making the commitment), but it is possible … WebMar 14, 2024 · Cryptographic primitives are low-level cryptographic algorithms that are thoroughly tested and often are used to design systems that use cryptography security protocols. Typically, a cryptographic primitive is designed to do one specific task or atomic task in a clearly defined manner and it is highly reliable to execute.

A way to visualize a commitment scheme is to think of a sender as putting a message in a locked box, and giving the box to a receiver. 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 security with respect to the hiding or binding properties. Another such flavour is … 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 individually separable values.
