Mathematical Mesh 3.0 Part I: Architecture Guide
draft-hallambaker-mesh-architecture-16
Abstract
The Mathematical Mesh is a Threshold Key Infrastructure that makes
computers easier to use by making them more secure. Application of
threshold cryptography to key generation and use enables users to
make use of public key cryptography across multiple devices with
minimal impact on the user experience.
This document provides an overview of the Mesh data structures,
protocols and examples of its use.
[Note to Readers] Discussion of this draft takes place on the
