Michael Egorov, MacLane Wilkison, David Nunez

TL;DR
NuCypher KMS introduces a decentralized key management system utilizing proxy re-encryption to securely manage and share encrypted data without relying on trusted centralized authorities, suitable for various sensitive applications.
Contribution
It presents a novel decentralized KMS that leverages proxy re-encryption, enabling secure data sharing without trusting a central service provider.
Findings
Provides secure encryption and access control in a decentralized network
Enables data sharing for diverse applications like healthcare and identity management
Establishes a security infrastructure comparable to SSL/TLS for decentralized apps
Abstract
NuCypher KMS is a decentralized Key Management System (KMS) that addresses the limitations of using consensus networks to securely store and manipulate private, encrypted data. It provides encryption and cryptographic access controls, performed by a decentralized network, leveraging proxy re-encryption. Unlike centralized KMS as a service solutions, it doesn't require trusting a service provider. NuCypher KMS enables sharing of sensitive data for both decentralized and centralized applications, providing security infrastructure for applications from healthcare to identity management to decentralized content marketplaces. NuCypher KMS will be an essential part of decentralized applications, just as SSL/TLS is an essential part of every secure web application.
