I performed the challenge concurrently on two separate computers and following
the roll of a dice chose to upload one of them. Machine 1 was a 2017-built
Hackintosh running macOS High Sierra 10.13.2. Machine 2 was running Windows 10
Home and has been in my possession for several years.
I performed a similar approach on both machines, firstly downloading rust. On
the Hackintosh this was achieved via Homebrew and on the Windows machine by
downloading directly from rust-lang.org. Both machines were running the latest
stable release of 1.22.1. On running the challenge on the Windows machine I
encounter a link.exe error which necessitated the additional downloading of
Visual Studio to fix and successfully run the challenge.
I downloaded the challenge file from the S3 link provided by Sean Bowe and used
git to clone the powersoftau repo with commit
Side Channel Defences
Entropy sources: For each machine, I chose a book from my library and randomly
selected words from each. My typing is terrible, so a number were misspelt
which I did not correct. In addition, I then performed an obligatory “mashing
of the keyboard” for added randomness.
Physical/electronic monitoring: I didn’t perform anything specific in this
regard albeit the challenge was performed concurrently on two machines. Both
computers were located in my basement and watched throughout by myself and dog
who, albeit slept through the majority of the process, did not raise any alarms
regarding physical intruders.
As above once both challenges were complete I rolled a dice (assigning odd
numbers to one computer and even to another) and uploaded the corresponding
chosen response. I have no intention to destroy either machine, but both
machines were shut down following completion of the challenge.
