Precise Subtyping for Asynchronous Multiparty Sessions
Silvia Ghilezan, Jovanka Pantović, Ivan Prokić +2
This paper presents the first formalisation of the precise subtyping relation for asynchronous multiparty sessions. We show that our subtyping relation is sound (i.e., guarantees s…
A Calculus for Modeling Floating Authorizations
Jovanka Pantovic, Ivan Prokic, Hugo Torres Vieira
Controlling resource usage in distributed systems is a challenging task given the dynamics involved in access granting. Consider, for instance, the setting of floating licenses whe…
A Typed Model for Dynamic Authorizations
Silvia Ghilezan, Svetlana Jakšić, Jovanka Pantović +2
Security requirements in distributed software systems are inherently dynamic. In the case of authorization policies, resources are meant to be accessed only by authorized parties,…
Precise subtyping for synchronous multiparty sessions
Mariangiola Dezani-Ciancaglini, Silvia Ghilezan, Svetlana Jakšić +2
The notion of subtyping has gained an important role both in theoretical and applicative domains: in lambda and concurrent calculi as well as in programming languages. The soundnes…
