[ANN] [Whitepaper] NuCypher KMS: Decentralized key management

[faragly]

NuCypher has partnered with LegalThings One, the essence of the partnership is mainly related to the use of re-encryption and live contracts in the Electronic Patient Dossier (EPD)

Our Mission & Values and why we're working on NuCypher 😃 https://blog.nucypher.com/nucyphers-mission-values-a94b2f1ce96e

I hope this ico does what it says as many have tried and failed. It will be very interesting to have this as the first ico to have a debit card able to use crypto on everyday purchases. This idea is revolutionary and I wish this team all the best and success in this market.

[mangkel]

with the NuCypher project we so get cryptographic access control easily and anywhere, I think this is a very nice and safe also for in store

We released a Go implementation of Umbral, our underlying cryptosystem, yesterday: https://blog.nucypher.com/introducing-goumbral-ce979e616359

Proposed staking economics paper has been published: https://blog.nucypher.com/nucypher-staking-economics-a7bb56b20716

This analyzes the proposed inflation dynamics of the NuCypher system.

I strongly support this project because this project is good concept and am optimistic this project will be successful and successful for me do not stop to hope for the success of this project. Smiley

A decentralized key management system based on blockchain is what the projects aim to provide which I think is a great concept and would be able to gain massive investors and collect large userbase with its concept and the team behind it is collectively most experienced and has executed the project nicely until now.

Why is PRE method more suitable for N: N communication than PKE method? And is there any further information / links for the use-case to manage a corporate password?

Bonjour Thales et STATION F  

Some further growth to announce:

Thales Group has accepted NuCypher for their Cybersecurity Programme at STATION F in Paris, France 🇫🇷. We look forward to exploring and creating opportunities with the other program members and Thales Group.

NuCypher is coming to Berlin this week and we couldn't be happier to keep the EU tour going.

Our first event: ZK0X02, September 5, hosted by zeroknowledgefm

We'll be presenting on-chain verification of the NuCypher protocol with ZK proofs

The idea is very good and if you actually get on in actualizing your plans, then I think it will be good.

Read this thread several times and still don't get the idea of the project.
Is there any other things i could learn about this project.

Imagine the following. You are trying to build an e2e encrypted group chat. For security, each message is encrypted with its own symmetric key, and you want to invite people to the chat or revoke access. You'd need to encrypt every message key for every participant.

Now imagine you want to grant access to all historical messages to a new participant. You'd need to encrypt a symmetric key for every historical message for him.

So, in brief, you reduce the number of cryptographic operations from `n_participants * n_objects` to just `n_objects`.

Now, imagine that participants would also need to encrypt messages (or files) they publish with everyone's public key. That's also not convenient and not necessarily always safe.

You can also check how e2e encryption / ACLs are currently being implemented in Swarm w/o using proxy re-encryption. They do pretty smart tricks to provide forward secrecy, but still, for every change they require the owner of the data to overwrite `log(N)` encrypted symmetric keys, and the owner of the data cannot trust third parties to write to their dataset.

This is a good overview talk by Arj, our product lead: https://youtu.be/J2kXIj6GTl0

What kind of use case would make sense when using origo network if we could use nucypher to create anonymity in existing blockchain?

[Trephyna]

This project seems cool to me .Hope this project will move further towards success.Good luck to everyone involved

Hello! Tell me please, do you have a Bounty campaign or airdrop? Give please the link.

[HARITE]

This idea is wonderful. I support you to become a concrete project. I also report to the community that I can spread.

[einsteinknaped]

This project very well it can help us control access to encrypted easy and whenever and where. I'm very pleased about it and people too.
