P2P social recovery system for secure backup/recovery of your secrets.

t,n threshold policy

An end-to-end application that shards your private key/secrets into multiple parts and sends it across to trusted human social accounts. Salient features include:

  • Collusion resistance: This ensures that the shard-recievers (Guardians) don't generate user's private key without the permission/knowledge of the users.
  • Implementation of modified Shamir secret algorithm(n,t): Shamir Secret algorithm forms the core of our system's logic.
  • Providing a secure backup option as there is no single point of failure: Storing a private key in a single place, makes it very vulnerable to attacks. Sharding a private key and storing it in multiple places is a much more secure way to backup.

INSTALLATION

1. npm install
2. cd ios
3. install pod
4. cd ..
5. npm run android

Use-case:-

The authenticator apps currently in the market do not allow the user to reclaim the accounts if their account/phone/application is lost. Our authenticator app makes it possible to securely reclaim a 2fa-enabled account / Keys if the user loses their phone. Share the account secrets among the user’s friends/family

The UX flow is:

  • The user will enter the email addrs of the peers with which it wants to share the shard, and contact each one of them to approve the request.

  • Once the user approves the requests, it's done.

  • For Recovery (Upon data loss), the user can send recollect requests (hints of the peers are written in the SLDealer file) to the peers to get their share back.

  • Once all the peers give the appropriate share back, the user can click on "Recover Key" to get all the accounts back!

Challenges:

  • Implementing Shamir's secret(collusion resistant) in JS.
  • Extending (2,3) Sharding algorithm to (n,t).
  • Improving Web 2.0 applications using Web 3.0 Technologies.
  • Implementing Decentralise Peer to Peer communication.
  • Integrating metamask in react native.
  • Integrating Push Protocol(P2P secure decentralise communication
