Pinocchio: verifiable computation revisited

1. Introduction 1.1 Motivation Imagine you want to do a complex computation, that you cannot carry out in your computer, or you need to get the results from a computer that you don't trust. How can you be sure it was done correctly without redoing it yourself or understanding

Functions are Vectors

[AI summary] The text discusses the representation of functions as vectors and their applications in various domains such as signal processing, geometry, and physics. It explains how functions can be treated as vectors in a vector space, leading to the concept of eigenfunctions and eigenvalues, which are crucial for understanding and manipulating signals and geometries. The text also covers different types of Laplacians, including the standard Laplacian, higher-dimensional Laplacians, and the Laplace-Beltrami operator, and their applications in fields like image compression, computer graphics, and quantum mechanics. The discussion includes spherical harmonics, which are used in representing functions on spheres, and their applications in game engines and glo...

Git-Ring: Easy & Flexible SSH Ring Signatures.

This is the companion post to a tool, git-ring, that I recently released on Github. Github/Gitlab makes the public keys of its users publicly available (at github.com/USERNAME.keys and gitlab.com/USERNAME.keys), this means that these services bind the users identity to public keys via this endpoint. Git-ring "exploits" this to enable the creation of (cryptographic) proofs showing membership among a set of users (or organizations) without revealing the identity of the person generating the proof. The public keys of everyone (including the signer) is automatically downloaded from Github, while the tool finds the correct private key on the signers local computer. All this combined makes using the tool pretty easy, as shown below, where we sign a message and the...
