I'd be shocked if the NSA hadn't "invented" differential cryptanalysis long before Shamir.

- caf 13y agoDoes that matter? If two people independently invent the same thing, they're both inventors with equal standing. The classic example being Leibniz and Newton with regards to calculus of infintesimals.
- ogreyonder 13y agoApparently it matters to the good people of Marshall, Texas. According to them, Whitfield Diffie didn't invent public key encryption for exactly that reason. Yeah, I'm more than a little bitter about the technologically illiterate being allowed to judge complex technology.
- Crito 13y agoIsn't it a given that they did? They strengthened DES's s-boxes against it 10 or so years before it was publicly discovered iirc.
- ars_technician 13y agoYou're right, that's precisely why they changed DES.
