Abstract. This paper introduces occam-π, an efficient and safe binding of key elements from Hoare’s CSP and Milner’s π-calculus into a programming language of industrial strength. A brief overview of classical occam is presented, before focussing on the extensions providing data, channel and process mobility. Some implementation details are given, along with current benchmark results. Application techniques exploiting mobile processes for the direct modelling of large-scale natural systems are outlined, including the modelling of locality (so that free-ranging processes can locate each other). Run-time overheads are sufficiently low so that systems comprising millions of dynamically assembling and communicating processes are practical on modest processor resources. The ideas and technology will scale further to address larger systems of arbitrary complexity, distributed over multiple processors with no semantic discontinuity. Semantic design, comprehension and analysis are made possible through a natural structuring of systems into multiple levels of network and the compositionality of the underlying algebra. 1

This article investigates if and how mobile agents can execute secure electronic transactions on untrusted hosts. An overview of the security issues of mobile agents is first given. The problem of untrusted (i.e., potentially malicious) hosts is one of these issues, and appears to be the most difficult to solve. The current approaches to counter this problem are evaluated, and their relevance for secure electronic transactions is discussed. In particular, a state-of-the-art survey of mobile agent-based secure electronic transactions is presented. Categories and Subject Descriptors: A.1 [Introductory and Survey]; E.3 [Data Encryption];

Effective intrusion detection capability is an elusive goal, not solved easily or with a single mechanism. However, mobile software agents go a long way toward realizing the ideal behavior desired in an Intrusion Detection System (IDS). This paper is an initial look at the relatively unexplored terrain of using mobile agents for intrusion detection and response. It looks not only at the benefits derived from mobility, but also those associated with software agent technology. We explore these benefits in some detail and propose a number of innovative ways to apply agent mobility to address the shortcomings of current IDS designs and implementations. We also look at new approaches for automating response to an intrusion, once detected.

This thesis explores the design and application of artificial immune systems (AISs), problem-solving systems inspired by the human and other immune systems. AISs to date have largely been modelled on the biological adaptive immune system and have taken little inspiration from the innate immune system. The first part of this thesis examines the biological innate immune system, which controls the adaptive immune system. The importance of the innate immune system suggests that AISs should also incorporate models of the innate immune system as well as the adaptive immune system. This thesis presents and discusses a number of design principles for AISs which are modelled on both innate and adaptive immunity. These novel design principles provided a structured framework for developing AISs which incorporate innate and adaptive immune systems in general. These design principles are used to build a software system which allows such AISs to be implemented and explored.

NOMADS is a mobile agent system that supports strong mobility (i.e., the ability to capture and transfer the full execution state of mobile agents) and safe Java agent execution (i.e., the ability to control resources consumed by agents, facilitating guarantees of quality of service while protecting against denial of service attacks). The NOMADS environment is composed of two parts: an agent execution environment called Oasis and a new Javacompatible Virtual Machine (VM) called Aroma. The combination of Oasis and the Aroma VM provides key enhancements over today s Java agent environments.

. The notion of trust is presented as an important component in a security infrastructure for mobile agents. A trust model that can be used in tackling the aspect of protecting mobile agents from hostile platforms is proposed. We dene several trust relationships in our model, and present a trust derivation algorithm that can be used to infer new relationships from existing ones. An example of how such a model can be utilized in a practical system is provided. 1
