Abstract

Low-security observable determinism (LSOD), as introduced by Roscoe and Zdancewic, is the simplest criterion which guar- antees probabilistic noninterference for concurrent programs. But LSOD prohibits any, even secure low-nondeterminism. Giffhorn developed an improvement, named RLSOD, which allows some secure low-nondeterminism, and can handle full Java with high precision. In this paper, we describe a new generalization of RLSOD. By applying aggressive program analysis, in particular dominators for multi-threaded programs, precision can be boosted and false alarms minimized. We explain details of the new algorithm, and provide a soundness proof. The improved RLSOD is integrated into the JOANA tool; a case study is described. We thus demonstrate that low-deterministic security is a highly precise and practically mature software security analysis method.
