Round: 9

Date: 2017-11-18

Procedure
=

I downloaded the challenge file from an Amazon S3 bucket set up by Sean Bowe. I 
computed a response locally using rustc 1.21.0 on a non-air-gapped MacBook Pro 
from mid-2012 running macOS High Sierra. I uploaded the response file to the 
same Amazon S3 bucket.

Side channel defenses
=

Entropy source: A literary excerpt of undisclosed provenance.

Physical/electronic monitoring: All steps performed from the comfort of my 
living room.  I played aloud the new Spoon album Hot Thoughts on a separate 
laptop while it computed.

I have no intention to destroy the compute node.
