It’s a strange, harsh world these days...
Newer technology is less secure, not more
- insecure media & message routing, complex design
- and we use electronic media for serious stuff
- this is great news for the bad guys
Fortunately, cryptography can do the impossible
- secure communication/storage over insecure media
Even better, good cryptography is cheap (same price as bad cryptography or no cryptography)
- minimal performance impact, no marginal cost
