Accord­ing to NSA’s Puz­zle Peri­od­i­cal, “Intel­li­gence. It’s the abil­i­ty to think abstract­ly. Chal­lenge the unknown. Solve the impos­si­ble. NSA employ­ees work on some of the world’s most demand­ing and exhil­a­rat­ing high-tech engi­neer­ing chal­lenges. Apply­ing com­plex algo­rithms and express­ing dif­fi­cult cryp­to­graph­ic prob­lems in terms of math­e­mat­ics is part of the work NSA employ­ees do every day.”
