We study the nature of the relationship between performance measures and privacy guarantees in the case study of an adaptive protocol for the secure transmission of real-time audio over the Internet. The analysis is conducted on a process-algebraic description of the audio mechanism by following a methodology that allows the modeler to (i) employ the noninterference approach to information flow theory for the analysis of security requirements, and (ii) derive performance measures obtained through markovian analysis techniques. The main result we present is that the analysis of performance properties helps to estimate the effectiveness (and to find a related countermove) of an attack that is captured by the security analysis.

Abstract

We study the nature of the relationship between performance measures and privacy guarantees in the case study of an adaptive protocol for the secure transmission of real-time audio over the Internet. The analysis is conducted on a process-algebraic description of the audio mechanism by following a methodology that allows the modeler to (i) employ the noninterference approach to information flow theory for the analysis of security requirements, and (ii) derive performance measures obtained through markovian analysis techniques. The main result we present is that the analysis of performance properties helps to estimate the effectiveness (and to find a related countermove) of an attack that is captured by the security analysis.
