Model checking tracebased information flow properties: For finite state systems and pushdown systems,Used
Delivery time: 8-12 business days (International)
Information flow properties are a way of specifying security properties of systems. A system is viewed as generating traces containing confidential and visible events (only the latter being observable by a lowlevel user) and the information flow properties specify restrictions on the kind of traces the system may generate, so as to restrict the amount of information a lowlevel user can infer about confidential events having taken place (or not) in an execution. Mantel identifies "basic security predicates or BSPs and shows them to be the building blocks of most of the known tracebased properties in the literature. Traditionally BSPs have been reasoned about via unwinding conditions that capture whether a system satisfies a particular BSP. First, we show that the checking of unwinding conditions can be simplified to checking conditions on a maximal simulation relation. Second, we show that the BSPs can be characterized in terms of regularity preserving languagetheoretic operations. This leads to a decision procedure for checking whether a finite state system satisfies a given BSP. Finally, we prove that the problem of verifying BSPs for pushdown systems is undecidable.
By changing our most important processes and
products, we have already made a big leap forward. This ranges from the
increased use of more sustainable fibers to the use of more
environmentally friendly printing processes to the development of
efficient waste management in our value chain.
