In this paper we start by reviewing both classical and probabilistic/quantitative approaches to program analysis. We shall provide a comparison of the two approaches. We shall use a simple information flow analysis to exemplify the classical approach. The existence of covert information flows through timing channels are difficult to detect using classical techniques; we show how such problems can be addressed using probabilistic techniques.

Abstract
In this paper we start by reviewing both classical and probabilistic/quantitative approaches to program analysis. We shall provide a comparison of the two approaches. We shall use a simple information flow analysis to exemplify the classical approach. The existence of covert information flows through timing channels are difficult to detect using classical techniques; we show how such problems can be addressed using probabilistic techniques.
