More from Whitfield Diffie

The most important impact of technology on communications security is that it draws better and better traffic into vulnerable channels.
Whitfield DiffieRead
In a sense, communications networks can be defined entirely by who has cryptographic keys, and I think a lot of networks will work that way in the future.
Whitfield DiffieRead
It's simply unrealistic to depend on secrecy for security in computer software. You may be able to keep the exact workings of the program out of general circulation, but can you prevent the code from being reverse-engineered by serious opponents? Probably not. The secret to strong security: less reliance on secrets.
Whitfield DiffieRead
It isn't that secrets are never needed in security. It's that they are never desirable.

I am much less concerned with whatever it is technology may be doing to people that what people are choosing to do to one another through technology. Facebook's reduction of people to predictively modeled profiles and investment banking's convolution of the marketplace into an algorithmic battleground were not the choices of machines.

Technological defeatism - a belief that, since a given technology is here to stay, there's nothing we can do about it other than get on with it and simply adjust our norms - is a persistent feature of social thought about technology. We'll come to pay for it very dearly.
