NuCypher 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 control, 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 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 will be an essential part of decentralized
applications, just as SSL/TLS is an essential part of every secure web application.
