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...
Information flow security properties such as noninterference ensure the protection of confidential data by strongly limiting the flow of sensitive information. However, to deal wi...
: This paper proposes a context-aware security service providing multiple authentications and authorization from a Security Level which is decided dynamically in a context-aware en...
The paper proposes an assessment scheme for the security properties of software components. The proposed scheme consists of three stages: (i) a system-specific security requireme...
We model security protocols as a game tree using concepts of game semantics. The model interprets protocol specifications as strategies over a game tree that represents the type ...
