I was asked a question regarding a particular species of unicorn at my last class, specifically the solution for a secure, clandestine, proprietary communications for a private group. They never go into too many details, which is due to either ignorance or OPSEC, but this isn't the first time this has happened.
My answer was this: Take the smartest kid in your group and pool your money to send him/her to the best college you can afford for an MS degree in electrical engineering/computer science. Think MIT. Now you have someone, presumably trusted, who can design your super secret, secret squirrel system for you.
The kid will also have the means to get his/her own HPJIE, and be able to provide adequately for his/her family before the TEOTWAWKI Zombie Apocalypse and Cannibalistic San Franciscan Invasion.
