This paper formalizes the folklore result that strongly-typed applets are more secure than untyped ones. We formulate and prove several security properties that all well-typed applets possess, and identify sufficient conditions for the applet execution environment to be safe, such as procedural encapsulation, type abstraction, and systematic type-based placement of run-time checks. These results are a first step towards formal techniques for developing and validating safe execution environments for applets.
