Markovian modeling for information leakage quantification

Information leakage quantifies the amount of bits of information about a system's secret that is obtained by an attacker able to observe the secret's output. It is common to model a terminating system as a channel matrix and to compute leakage as the mutual information between the input and output of the channel. Hovewer, Markovian models can model systems in a more concrete way, considering the system's control flow and in many cases producing a smaller model, and can also model non-terminating systems. We will show how Markovian models can be used to model a system's specification and to synthesize the implementation with the highest leakage if it exists. We will discuss leakage and leakage rate of non-terminating systems, and we will show how the Markovian analysis can be used to implement a fast leakage computation algorithm based on trace analysis, currently implemented in the state-of-the-art QUAIL tool.
