This paper presents the authors' work in progress on efficient and confidentiality-aware access control for software-as-a-service applications. In SaaS, a tenant organization rents access to a shared, typically web-based application. Access control for these applications requires large amounts of fine-grained data, also from the remaining on-premise applications, of which often sensitive application data. With current SaaS applications the provider evaluates both provider and tenant policies. This forces the tenant to disclose its sensitive access control data and limits policy evaluation performance by having to fetch this data.
