Reading the presentation of the upcoming 11th International Workshop
on Plan 9, on http://iwp9.org, I notice that:
"This year, our host having a focus on computer security, papers about
cryptography, authentication, fault tolerance, robustness, security
applications, error detection and remediation, software reliability,
etc. are particularly welcome."
I'd like to add something (if people at the CNAM read this too...).
When speaking about cryptography / security, one needs to speak also
about computability.
"Computing" or "calculating" is the way humans track nature, by
generally beating around the bushes (indirect, lengthy access). There
are equations that we can write, but that we can't solve while soap
bubbles, for example, have no difficulty "calculating" (wrong verb)
minimal surfaces that we don't know how to calculate.
So if organizers or researchers in the field could add a presentation
about the limit of numerical, digital, and propose an answer to the
following question (perhaps by crossing swords with physicists),
I would be very interested:
"Cryptography for security relies on how long and how computer
intensive is a digital computation to solve some equations. But
how to be reassured about the digital security of something, if
one can not prove that there are no "soap bubbles" able to analogically
solve the equations that computers are unable to solve?"
More broadly, the main question is: what are the limits of numerical,
digital, computation? What is it obviously good at? What is it open
to question good at? Does it rule out experiments?---experiment:
"analogical computing" i.e. letting Nature doing the calculus.
PS: could someone at the Plan9 Foundation update the copyright on the
bottom of the pages? It is an easy way to show that things are still
alive ;-)
