We formalize a wide variety of Volpano/Smith-style noninterference notions for a while language with parallel composition. We systematize and classify these notions according to compositionality w.r.t. the language constructs. Compositionality yields sound syntactic criteria (a.k.a. type systems) in a uniform way.BSD License
