Anastasis is a key recovery system that allows the user to securely deposit shares of a core secret with an open set of escrow providers, to recover it if the secret is lost. The core secret itself is protected from the escrow providers by giving each provider only part of the information, and additionally by encrypting it with an identity-based key unknown to the providers.The main objective of Anastasis is to ensure that the user can reliably recover the core secret, while making this as difficult as possible for everyone else.
