I found an interesting concept in this paper, page 13, (Link to the paper) called "Decentralized private key generation", as follows:
"Decentralized private key generation – Multiple Enigma nodes locally create a segment of the key, whereas the full key is only ever assembled by the user. No trail of evidence is left anywhere."
I want to implement such an approach and I need to know the process step by step.
- We have
nuntrusted parties in a network.
- Parties are identified only their public keys.
- The target is to generate a single new private key across these parties.
- Only one of these parties eventually can access to this private key. We call this party as "winner".
- This winner party will be selected by a random process.
- This winner party will be selected as a "voter", such that any party holding that private key will be able to vote using this private key and the rest parties will accept this vote.
- So, verifying this vote is crucial and the rest of parties will be only related public key of that private key.
Is this process possible using a distributed private key generation ? And if yes, what is the steps?
If you need any more detailed information about the scenario, please let me know.
