In this paper, we introduce a notion of restricted revocable delegation and study its consequences in language-based security. In particular, we add this notion by means of delegate and revoke commands to a simple imperative programming language. We then define an operational semantics for our programming language, in the Natural Semantics style of Gilles Kahn. We briefly discuss our initial ideas about the security properties of the semantics, which are extensions of existing variations of the renowned non-interference property, e.g., in the context of delimited information release.
