CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishA static approach is proposed to study secure composition of software. We extend the λ calculus with primitives for invoking services that respect given security requirements. Security critical code is enclosed in policy fram-ings with a possibly nested, local scope. Policy framings enforce safety and liveness properties of execution histo-ries. The actual histories that can occur at runtime are over-approximated by a type and effect system. These ap- proximations are model-checked to verify policy framings within their scopes. This allows for removing any run- time execution monitor, and for selecting those services that match the security requirements.

| Abstract: | A static approach is proposed to study secure composition of software. We extend the λ calculus with primitives for invoking services that respect given security requirements. Security critical code is enclosed in policy fram-ings with a possibly nested, local scope. Policy framings enforce safety and liveness properties of execution histo-ries. The actual histories that can occur at runtime are over-approximated by a type and effect system. These ap- proximations are model-checked to verify policy framings within their scopes. This allows for removing any run- time execution monitor, and for selecting those services that match the security requirements. |
