  1. 1. Language Support for Controlling Timing-Based Covert Channels

    Författare :Alejandro Russo; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; information-flow; language-based security; semaphores; non-interference; Haskell; library; concurrency; internal timing covert channel;

    Sammanfattning : The problem of controlling information flow in multithreaded programs remains an important open challenge.A major difficulty for tracking information flow in concurrent programs is due to the internal timing covert channel. LÄS MER

  7. 5. MAC, A Verified Information-Flow Control Library

    Författare :Marco Vassena; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Haskell; NonInterference; Agda; Functional Programming; Information-Flow Control;

    Sammanfattning : Information Flow Control (IFC) is a language-based security mechanism that tracks where data flows within a program and prevents leakage of sensitive data. IFC has been embedded in pure functional languages such as Haskell, in the form of a library, thus reducing the implementation and maintenance effort and fostering a secure-by-construction programming-model.
