Scientists have launched the satellite with the most secured crypto-channel in the world! It is quantum channel (BB84). But hackers had managed to sniff it. You should help those hackers to find out what was in the satelliteβΒΒs transmission. File: https://mega.nz/#!jfpChKTT!TTDfy2l1hGrNwDrM3DQEjX6kmUVDy5DmMatnka5NvXc

any hint ? what is the flag format?
Correct me if i'm wrong, but according to the bb84 protocol, transmission2 and transmission3 should be the exchange of bases, so the last transmission file was misleading (otherwise, good challenge)

Thank for this challenge, I've learnt sth.
Thanks for this challenge, I discovered BB84. π

Don't give up on this one. It's very doable and worth the effort. I wasted a lot of time because I was trying to decode 0,45,90,135 as 1,0,0,1 (per an online chart) when I should have been using 0,0,1,1. You'll see what I mean...
