SMT-Based Verification of Software Countermeasures against Side-Channel Attacks [chapter]

Hassan Eldib, Chao Wang, Patrick Schaumont
2014 Lecture Notes in Computer Science  
In addition to checking whether the sensitive data are masked, we also check whether they are perfectly masked, i.e., whether the joint distribution of any d intermediate computation results is independent  ...  We encode this verification problem into a series of quantifier-free first-order logic formulas, whose satisfiability can be decided by an off-the-shelf SMT solver.  ...  This work is supported in part by the NSF grant CNS-1128903 and the ONR grant N00014-13-1-0527.  ...

A Simple Parameterization Coupling the Convective Daytime Boundary Layer and Fair-Weather Cumuli

Larry K. Berg, Roland B. Stull
2005 Journal of the Atmospheric Sciences  
In order to predict sub-grid boundary-layer cumuli in a climate model, the JFD must be parameterized.  ...  The parameterized JFDs can be used with the mean temperature and humidity profile to predict the amount and size distribution of boundary-layer cloud cover.  ...  The CuP parameterization can also be improved, and verification efforts should continue. The CuP scheme should be coupled with a single-column model of the atmosphere.  ...

A cut-off approach for bounded verification of parameterized systems

Qiusong Yang, Mingshu Li
2010 Proceedings of the 32nd ACM/IEEE International Conference on Software Engineering - ICSE '10  
The model checking of parameterized systems, a parametric infinite family of systems, is to decide if a property holds in every size instance.  ...  In this paper, a novel approach, called Forward Bounded Reachability Analysis (FBRA), based upon the cut-off on the maximum lengths of paths is proposed for the verification of parameterized systems.  ...  Acknowledgements The work was partially done during the first author's visit to the Laboratory for Advanced Software Engineering Research (LASER) in the Department of Computer Science at the University  ...
