TY - JOUR T1 - A modal type theory for formalizing trusted communications JF - Journal of Applied Logic Y1 - 2012 A1 - Primiero, Giuseppe A1 - Taddeo, Mariarosaria AB -

This paper introduces a multi-modal polymorphic type theory to model epistemic processes characterized by trust, defined as a second-order relation affecting the communication process between sources and a receiver. In this language, a set of senders is expressed by a modal prioritized context, whereas the receiver is formulated in terms of a contextually derived modal judgement. Introduction and elimination rules for modalities are based on the polymorphism of terms in the language. This leads to a multi-modal non-homogeneous version of a type theory, in which we show the embedding of the modal operators into standard group knowledge operators.
