Abstract
(English)
We show that team automata (TA) are well suited to model secure multicast/broadcast communication with possible packet loss. This is a consequence of the natural way in which one-to-many (one-to-all) transmissions typical of multicast (broadcast) sessions can be modelled as communications between the component automata (CA) constituting a TA. To this aim, we use TA to model an instance of the EMSS multicast protocol family. In addition, we investigate a formulation of the Generalized Non-Deducibility on Compositions (GNDC) schema in terms of TA with the aim to embed TA in this well-established analysis framework. We intend to use this new setting for the formal verification of security properties for stream signature protocols
