Flow-sensitive semantics for dynamic information flow policies
Niklas Broberg, David Sands · 2009
Dynamic information flow policies, such as declassification, are essential for practically useful information flow control systems. However, most systems proposed to date that handle dynamic information flow policies suffer from a common drawback. They build on semantic models of security which are inherently flow insensitive, which means that many simple intuitively secure programs will be considered insecure.
