Hi

We finally did it. Thanks to Sean, Jason and the Zcash Foundation for 
make it possible.


Here our signed report.

Round: 70
Date: 2018-03-06
Name: Zcash FR Team
Location: Paris, FR


Preparation steps
=

Zcash FR Team is currently compose of 3 members. Each member brings is 
own computer prepared by himself. We did not talk to each other which 
preparation was made neither which software or version was installed.


Sidechannel Defences


The computing process was done in the flat of a Zcash FR Team member. In 
this flat there was the 3 members of Zcash FR Team and nobody else.

Computing was done offline.

Procedure
=

We start with 3 computers ready to compute. For convenience reason we 
needed to use 1 computer so we took 1 computer at random and get it off 
the computing process.


Then we downloaded the challenge file on the 2 computers selected to 
participate.


The text entered to provide additional entropy was different on the 2 
computers.

It was composed of :
- - - Random type
- - - Name of Zcash FR Team members
- - - Information display on TV channel
- - - Play card picked randomly


After the response file was generated on both computer we decided to 
play a video game to decide which response file will be send. The winner 
send is own response file.



The BLAKE2b hash of `./response` is:
