چکیده انگلیسی
Secrecy is fundamental to computer security, but real systems often cannot avoid leaking some secret information. For this reason, it is useful to model secrecy quantitatively, thinking of it as a “resource” that may be gradually “consumed” by a system. In this paper, we explore this intuition through several dynamic and static models of secrecy consumption, ultimately focusing on (average) vulnerability and min-entropy leakage as especially useful models of secrecy consumption. We also consider several composition operators that allow smaller systems to be combined into a larger system, and explore the extent to which the secrecy consumption of a combined system is constrained by the secrecy consumption of its constituents.
