“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.”

Brian Snow, Former Technical Director of the US National Security Agency (NSA), "We need assurance!", 1999-2008

"In the medium term, we need to be prepared for the eventuality that large quantum computers could be built: this would require an upgrade of most symmetric cryptographic algorithms and a completely new generation of public-key algorithms."
