To investigate the interdependencies existing among deontic positions (like powers and obligations) and the ontology defined by an institution, we have proposed to model instituti...
In this paper we propose a new designated verifier signature scheme based on the threshold signature scheme presented [8] by Ghodosi and Pieprzyk. The advantages of the new scheme ...
Multi-Designated Verifier Signatures (MDVS) are privacy-oriented signatures that can only be verified by a set of users specified by the signer. We propose two new generic constru...
In this paper we show a novel method for modelling behaviours of security protocols using networks of communicating automata in order to verify them with SAT-based bounded model ch...
We consider the amount of communication required to verify the outcome of the Vickrey-Clarke-Groves (VCG) mechanism: an efficient allocation together with incentivizing VCG paymen...
