|Title: ||Quantification of Integrity|
|Authors: ||Clarkson, Michael R.|

quantitative information flow
|Issue Date: ||12-Jan-2011|
|Abstract: ||Three integrity measures are introduced: contamination, channel
suppression, and program suppression. Contamination is a measure of
how much untrusted information reaches trusted outputs; it is the dual
of leakage, which is a measure of information-flow confidentiality.
Channel suppression is a measure of how much information about inputs
to a noisy channel is missing from channel outputs. And program
suppression is a measure of how much information about the correct
output of a program is lost because of attacker influence and
implementation errors. Program and channel suppression do not have
confidentiality duals. As a case study, the relationship between
quantitative integrity, confidentiality, and database privacy is
