Improved Bounds on Security Reductions for Discrete Log Based Signatures
Despite considerable research efforts, no efficient reduction from the discrete log problem to forging a discrete log based signature (e.g. Schnorr) is currently known. In fact, ne...

On Presburger Liveness of Discrete Timed Automata
Using an automata-theoretic approach, we investigate the decidability of liveness properties (called Presburger liveness properties) for timed automata when Presburger formulas on ...
