Preemptive mobile code protection using spy agents

This thesis introduces 'spy agents' as a new security paradigm for evaluating trust in remote hosts in mobile code scenarios. In this security paradigm, a spy agent, i.e. a mobile agent which circulates amongst a number of remote hosts, can employ a variety of techniques in order to both appear 'normal' and suggest to a malicious host that it can 'misuse' the agent's data or code without being held accountable. A framework for the operation and deployment of such spy agents is described. Subsequently, a number of aspects of the operation of such agents within this framework are analysed in greater detail. The set of spy agent routes needs to be constructed in a manner that enables hosts to be identified from a set of detectable agent-specific outcomes. The construction of route sets that both reduce the probability of spy agent detection and support identification of the origin of a malicious act is analysed in the context of combinatorial group testing theory. Solutions to the route set design problem are proposed. A number of spy agent application scenarios are introduced and analysed, including: a) the implementation of a mobile code email honeypot system for identifying email privacy infringers, b) the design of sets of agent routes that enable malicious host detection even when hosts collude, and c) the evaluation of the credibility of host classification results in the presence of inconsistent host behaviour. Spy agents can be used in a wide range of applications, and it appears that each application creates challenging new research problems, notably in the design of appropriate agent route sets

Mobile-agent based multi-constraint one-to-many bilateral e-Negotiation framework

The thesis proposes a multi-constraint one-to-many bilateral e-Trade negotiation framework. It deploys mobile agents in negotiation, considers trading competition between vendors and search space, efficiently manages the risk of losing top utility offers that expire before the negotiation deadline, accurately evaluates offers, and truly maintains the security of negotiation data

Unfinished Histories

Colonial memory and interdisciplinary memorialization across Congo, Rwanda, Burundi and Belgium Belgian colonialism was short-lived but left significant traces that are still felt in the twenty-first century. This book explores how the imperial past has lived on in Belgium, but also in the Democratic Republic of the Congo, Rwanda and Burundi. The contributing authors approach colonial legacies from an interdisciplinary perspective and examine how literature, politics, the arts, the press, cinema, museal practices, architecture, and language policies – but also justice and ethics – have been used to critically revisit this period of African and European history. Whilst engaging with significant figures such as Sammy Baloji, Chokri Ben Chikha, Gaël Faye, François Kabasele, Alexis Kagame, Edmond Leplae, VY Mudimbe, Fiston Mwanza Mujila, Joseph Ndwaniye, and Sony Labou Tansi, this book also analyses the role of places such as the AfricaMuseum, Bujumbura, Colwyn Bay, Kongolo, and the Virunga Park to appraise the links between memory and the development of a postcolonial present. Contributors: Sarah Arens (University of Liverpool), Robert Burroughs (Leeds Beckett), Bambi Ceuppens (AfricaMuseum), Matthias De Groof (University of Antwerp), Catherine Gilbert (University of Newcastle), Chantal Gishoma (University of Bayreuth), Hannah Grayson (University of Stirling), Dónal Hassett (University of Cork), Sky Herington (University of Warwick), Nicki Hitchcott (University of St Andrews), Yvette Hutchison (University of Warwick), Albert Kasanda (Charles University, Prague), Maëline Le Lay (CNRS/ THALIM, Sorbonne nouvelle), Reuben Loffman (Queen Mary University of London), Caroline Williamson Sinalo (University of Cork) Ebook available in Open Access.
