Mathematical models of information security
Chris Hankin · Engineering & Technology Reference · 2012
In this short article, the authors will present a number of mathematical models of information security. They will start with some of the earliest work which focused on access control. The unifying theme throughout the study is information flow. They will move from lattice-based models through to the more recent information theoretic and probabilistic models. These latter models recognise that, in most systems, some information flow is inevitable but that it is important to be able to quantify this.
