Mobile agents offer a new paradigm for distributed computation, but their potential benefits must be weighed
against the very real security threats they pose. These threats originate not just in malicious agents but in
malicious hosts as well.
In this article, we present our security model for the IBM Aglets Workbench, a Java-based environment for
building mobile agent applications. We detail both the security model and the corresponding security
architecture that represents a framework for the inclusion of security services in future releases of the AWB.
This work therefore represents an additional step toward the comprehensive security model required for
widespread commercial adoption of mobile agent systems to occur.
