We present a novel progress-sensitive, ow-sensitive hybrid information-ow control monitor for an imperative interactive language. Progress-sensitive information-ow control is a strong information security guarantee which ensures that a program's progress (or lack of) does not leak information. Flow-sensitivity means that this strong security guarantee is(More)
