By adapting a recent Hidden-Markov denotational model for non-interference security, so that it becomes "collateral aware", we give techniques and examples (e.g.public-key encryption) to show how collateral ...

The security requirement in this environment is that data values from a plaintext domain of size N should not be leaked to within an interval of size H . ...
Therefore, the goal of our scheme is not to completely prevent leakage; rather, we aim to minimize the leakage bandwidth, measured in terms of the number of queries required to breach the security constraint ...

We use our model to explore some algebraic properties of programs which contain secrets that can be updated, and which are valid in arbitrary contexts made up of possibly freshly declared secrets. ...
