Blindstore
the first stone for a secure communication protocol
Why Blindstore?
Only partial solutions
They can hide the communication
But not the fact that A and B are communicating
Private communication
It can't be that hard, can it?
On the internet...
Bob's location changes several times per day
Then you need a new phonebook!
But the Internet Phonebook™ is a bit too heavy
Ok then,
What if we have a single central Internet Phonebook™?
And then we call an operator and ask for the updated Bob's location
But wait!
We don't know if the operator is an evil NSA agent!
What we need is...
An oblivious operator
The hackathon
Three fronts
Research, hacking & branding
Research
We started with a paper from 2013:
Single-Database Private Information Retrieval from Fully Homomorphic Encryption[1]
Hacking
Then we got our hands dirty:
But we also took care of making it easy to use:
- We wrote documentation for Blindstore client
- And tests for pyScarab (passing in Travis!)
Branding
What about having some identity?
Our tools
For hacking:
For collaborating:
For documenting:
You can find us here:
And this is the demo
So that is Blindstore
Any questions?
