Abstract

In this paper, we introduce a functional language which facilitates the mobility of code between the sites of a distributed system. We observe that code mobility renders systems with limited resources vulnerable to denial-of-service attacks. Languages which are designed with the objective of preventing these attacks would benefit from static analysis which can expose the resource consumption of programs. In functional computation there is a close connection between the consumption of resources and the flow of control within the system. We show that it is possible to exploit type systems to perform distributed control flow analysis and discuss the potential applications of such analyses in promoting security of resource-sensitive systems.
