Terrorism is a crime against the mind. We win by refusing fear.

For if we are observed in all matters, we are constantly under threat of correction, judgment, criticism, even plagiarism of our own uniqueness. We become children, fettered under watchful eyes, constantly fearful that-either now or in the uncertain future-patterns we leave behind will be brought back to implicate us, by whatever authority has now become focused upon our once-private and innocent acts. We lose our individuality, because everything we do is observable and recordable.

Anyone, from the most clueless amateur to the best cryptographer, can create an algorithm that he himself can't break.

It is poor civic hygiene to install technologies that could someday facilitate a police state.

It's certainly easier to implement bad security and make it illegal for anyone to notice than it is to implement good security.

The more we expect technology to protect us from people in the same way it protects us from nature, the more we will sacrifice the very values of our society in futile attempts to achieve this security.

The mantra of any good security engineer is: "Security is a not a product, but a process." It's more than designing strong cryptography into a system; it's designing the entire system such that all security measures, including cryptography, work together.
