This paper describes a counter scheme that uses hash functions to count how many times the user is allowed to play protected content in a DRM-enabled player. The proposed basic sc...
This paper describes an approach and support tool for the modelling and analysis of proposed reconfigurations to complex systems. The configuration models used are quick to constr...
—In this work we propose a novel tree representation for RLC circuits. Genetic programming based on the tree representation is described and applied to passive filter synthesis p...
— This paper analyzes the security of a new multistage encryption system (MES) recently proposed in ISCAS’2004. It is found that MES is insecure against a differential chosenpl...
This work proposes a scheme for multi–resolution representation of union of balls in the plane. This representation is inspired by curvature motion for smooth curves. More precis...
