We present a tool, called CAsCaDE, to check assertions in C programs as part of a multi-stage verification strategy. CAsCaDE takes as input a C program and a control file (the outp...
The problem of finding a graceful labelling of a graph, or proving that the graph is not graceful, has previously been modelled as a CSP. A new and much faster CSP model of the pro...
We present the first efficient group signature scheme that is provably secure without random oracles. We achieve this result by combining provably secure hierarchical signatures i...
Arbitrary public announcement logic (APAL) is an extension of multi-agent epistemic logic that allows agents' knowledge states to be updated by the public announcement of (pos...
In this work we present the principles of a flexible quantum key distribution (QKD) system using quadraturephase-shift-keying (QPSK) base and symbol encoding and dualthreshold bala...
