Verifying Weak Probabilistic Noninterference

Weak probabilistic noninterference is a security property for enforcing confidentiality in multi-threaded programs. It aims to guarantee secure flow of information in the program and ensure that sensitive information does not leak to attackers. In this paper, the problem of verifying weak probabilistic noninterference by leveraging formal methods, in particular algorithmic verification, is disc...

Probabilistic Noninterference through Weak Probabilistic Bisimulation

To be practical, systems for ensuring secure information flow must be as permissive as possible. To this end, the author recently proposed a type system for multi-threaded programs running under a uniform probabilistic scheduler; it allows the running times of threads to depend on the values of variables, provided that these timing variations cannot affect the values of variables. But these tim...

Probabilistic Noninterference

We formalize a probabilistic noninterference for a multi-threaded language with uniform scheduling, where probabilistic behaviour comes from both the scheduler and the individual threads. We define notions probabilistic noninterference in two variants: resumption-based and trace-based. For the resumption-based notions, we prove compositionality w.r.t. the language constructs and establish sound...

Formalizing Probabilistic Noninterference

We present an Isabelle formalization of probabilistic noninterference for a multi-threaded language with uniform scheduling. Unlike in previous settings from the literature, here probabilistic behavior comes from both the scheduler and the individual threads, making the language more realistic and the mathematics more challenging. We study resumption-based and trace-based notions of probabilist...

Checking probabilistic noninterference using JOANA

JOANA is a tool for software security analysis, checking up to 100kLOC of full multi-threaded Java. JOANA is based on sophisticated program analysis techniques and thus very precise. It includes a new algorithm guaranteeing probabilistic noninterference, named RLSOD. JOANA needs few annotations and has a nice GUI. The tool is open source and was applied in several case studies. The article pres...
