Abstract. We present a method to specify software for a special kind of safetycritical embedded systems, where sensors deliver low-level values that must be abstracted and pre-proc...
Security metrics are the tools for providing correct and upto-date information about a state of security. This information is essential for managing security efficiently. Although...
Given a program S and a precondition Q, the strongest postcondition, denoted sp(S Q), is defined as the strongest condition that holds after the execution of S, given that S term...
In order to solve future Multi Level Security (MLS) problems, we have developed a solution based on the DARPA Polymorphous Computing Architecture (PCA). MLS-PCA uses a novel distr...
As a program evolves, it becomes increasingly difficult to understand and reason about changes in the source code. Eventually, if enough changes are made, reverse engineering and ...
