A Calculus for Shapes in Time and Space
We present a spatial and temporal logic based on Duration Calculus for the specification and verification of mobile real-time systems. We demonstrate the use of the formalism and...

By Reason and Authority: A System for Authorization of Proof-Carrying Code
We present a system, BLF, that combines an authorization logic based on the Binder language with a logical framework, LF, able to express semantic properties of programs. BLF is a...

Guiding Program Development Systems by a Connection Based Proof Strategy
We present an automated proof method for constructive logic based on Wallen’s matrix characterization for intuitionistic validity. The proof search strategy extends Bibel’s con...

Improving the quality of ring oscillator PUFs on FPGAs
Physical Unclonable Functions (PUFs) based on Ring Oscillators (ROs) are a promising primitive for FPGA security. However, the quality of their implementation depends on several d...

Axiomatisation and Decidability of Multi-dimensional Duration Calculus
We investigate properties of a spatio-temporal logic based on an n-dimensional Duration Calculus tailored for the specification and verification of mobile real-time systems. Aft...
