“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.”

Brian Snow, Former Technical Director of the US National Security Agency (NSA), "We need Assurance", AusCERT 2008

“Systems built without requirements cannot fail; They merely offer surprises. Usually unpleasant!

Robert Morris, former Chief Scientist of the US National Security Agency (NSA), National Computer Security Center, 1995

“The time needed to factor an RSA integer is the same order as the time needed to use that same integer as modulus for a single RSA encryption.   In other words, it takes no more time to break RSA on a quantum computer (up to a multiplicative constant) than to use it legitimately on a classical computer.”

Professor Gilles Brassard,  "Quantum Information Processing: The Good, the Bad and the Ugly", 1997

"Even a relatively small quantum computer, one that had a few tens of thousands of qubits, could consider so many different values at once that it would be able to break all known [ed: RSA, D&H, ECC, AES-128] codes commonly used for secure Internet communication.”

Prof Seth Lloyd of MIT, MIT Review 2008

“Consider the use of smart cards ... for especially critical functions.  Although more costly than software, when properly implemented the assurance gain is great.  The form-factor is not as important as the existence of an isolated processor and address space for assured operations – an ‘Island of Security,’ if you will.  Such devices can communicate with each other through secure protocols and provide a web of security connecting secure nodes located across a sea of insecurity in the global net.”

“Build-in Security: Ensure that security is considered and built into the design of new infrastructure, so that our critical assets are protected from the start and more resilient to naturally-occurring and deliberate threats throughout their life-cycle."

Obama-Biden Plan, Agenda: Homeland Security, December 2008

“The more complex the threats become, the more you have to do the basics and groundwork really well. Staying aware and on top of new vulnerabilities and ensuring that patches and software updates are rapidly implemented is crucial.”

Jeff Shipley, Cisco Intelligence Collection Manager, Cisco 2008 Annual Security Report

"My colleagues at MIT and I have been building simple quantum computers and executing quantum algorithms since 1996, as have other scientists around the world. Quantum computers work as promised. If they can be scaled up, to thousands or tens of thousands of qubits from their current size of a dozen or so, watch out!”

Prof Seth Lloyd of MIT, MIT Review 2008

“Never underestimate the attention, risk, money and time that an opponent will put into reading traffic.”

“We are a cyber nation. The U.S. information infrastructure--including telecommunications and computer networks and systems and the data that reside on them--is critical to virtually every aspect of modern life. This information infrastructure is increasingly vulnerable to exploitation, disruption, and destruction by a growing array of adversaries.”

The National Coordination Office (NCO) for Networking Information Technology Research and Development (NITRD), Federal Register: December 30, 2008 (Volume 73, Number 250).

“So the threat to cryptography is well understood due to work by Peter Shor and others. A symmetric algorithm like AES or others standard crypto processes is cut (of) key-size in half, which is a dramatic reduction. ... For key management purposes, against the RSA and the Diffie-Hellman and stuff, they flat-line under a quantum computer.”

Brian Snow, Former Technical Director of the US National Security Agency (NSA), Public Key Cryptography 30th Anniversary Conference, Dec 2006

"Security and dependability issues typically go along with the life cycle of a technology.  The trend to first deploy a technology and later fix its problems – typically driven by economic motives – is gradually making way for security by design, resulting in improved security at the beginning of the life cycle."

"Given their power to intercept and disrupt secret communications, it is not surprising that quantum computers have the attention of various U.S. government agencies.  The National Security Agency, which supports research in quantum computing, candidly declares that given its interest in keeping U.S. government communications secure, it is loath to see quantum computers built. On the other hand, if they can be built, then it wants to have the first one.”

Prof Seth Lloyd of MIT, MIT Review 2008

“It's not good enough to have a system where everyone (using the system) must be trusted, it must also be made robust against insiders!”

Robert Morris, former Chief Scientist of the US National Security Agency (NSA), National Computer Security Center, "Crypto '95 invited talks by R. Morris and A. Shamir", 1995

"But conventional security is not enough. The complexity of today's operational environment means organisations must embrace a level of business resilience that is normally associated with the protection of critical national infrastructure."

Public key crypto key exchanges (RSA, D&H, ECC) would be ‘flat-lined’ under a quantum computer attack … "Open Problem”

Brian Snow, Former Technical Director of the US National Security Agency (NSA), Public Key Cryptography 30th Anniversary Conference, Dec 2006

“Advances have often been done in steps, and beyond approximately 10 years into the future, the general feeling among ECRYPT partners is that recommendations made today should be assigned a rather small confidence level, perhaps in particular for asymmetric primitives.”
