The Thermodynamics of Confidentiality

Pasquale Malacaria

(Queen Mary, University of London)

What has a property (confidentiality) of a human artifact (software) to do with the most basic laws of physics (second law of thermodynamics)? I came across these questions and some answers in recent years. I found it a fascinating tale about the physical value of information and the cost incurred in protecting it. Some of these results are fundamental limits on any physical device guaranteeing a certain degree of confidentiality while others relate to physical properties of timing channels. This talk will survey (in accessible form) some of these results/ideas, their interpretation and possible research directions. This is a joint work with Fabrizio Smeraldi.
