pointerLe difficoltà di una email più sicura

Matthew Green, professore alla Johns Hopkins University, spiega sul New Yorker perché la maggior parte delle email scambiate nel mondo non sono criptate. Un programma come P.G.P. (Pretty Good Privacy) che esiste dal 1991 richiede uno sforzo troppo significativo per l’utente medio:

Encrypting e-mail is just hard. Before you can send your friend an encrypted message, she must first install the software, generate an encryption key pair, and deliver the public portion to you. You must then download and install that key on your own computer and verify that it’s the right key—not a fake one sent to trick you. You must repeat this process for everyone else you want to talk to. And that’s before sending a single message.
