• “Briefly and simply, assurance work makes a user or a creditor more confident that the system works as intended without flaws, without surprises, even in the presence of malice.” … “The major shortfall is absence of assurance or safety mechanisms in software.  If my car crashed as often as my computer does, I’d be dead by now.”

  • "Today’s systems must anticipate future attacks. Any comprehensive system – whether for authenticated communications, secure data storage, or electronic commerce – is likely to remain in use for five years or more. It must be able to withstand the future: smarter attackers, more computational power, and greater incentives to subvert a widespread system. There won’t be time to upgrade it in the field."

quote: ARDA, Code breaking quantum computers may be a decade or two away

The future ability of quantum computers might be a decade or two away, their future ability to break public-key cryptography has important implications for the encryption of highly sensitive information today.

For these applications, we must already design new public-key cryptosystems and one-way functions that are immune to quantum cryptanalysis.
