  • This work is devoted to conducting a new study for global dynamics and numerical simulation of a discrete-time computer virus propagation model, which was constructed in our recent work. By utilizing well-known results on asymptotic stability of discrete-time dynamical systems, we establish the global asymptotic stability of a unique viral equilibrium point, whereas only its local asymptotic stability was previously analyzed.

  • Intrusion Detection (ID) is one of the active branches in network security research field. Many technologies, such as neural networks, fuzzy logic and genetic algorithms have been applied in intrusion detection and the results are varied. In this thesis, an Artificial Immune System (AIS) based intrusion detection is explored. AIS is a bio-inspired computing paradigm that has been applied in many different areas including intrusion detection.

  • This thesis proposes and implements a new and novel solution on simulators and real devices to solve the mobility problem in a VPN. The new solution adds mobility support to existing L2TP/IPsec (Layer 2 Tunneling Protocol/IP Security) tunnels. The new solution tunnels Layer 2 packets between VPN clients and a VPN server without using Mobile IP, without incurring tunnel-re-establishment at handoff, without losing packets during handoff, achieves better security than current mobility solutions for VPN, and supports fast handoff in IPv4 networks.

  • Several studies have been carried out by optimising only the cost. They have not considered some other risk factors such as political and economic factors in their modelling. Currently, there is no generalised model available to determine the optimal sourcing locations incorporating important factors including risks in international LNG trading. In this study, 12 risk factors were taken into consideration to evaluate the risk.

  • Privacy-preserving frequency mining is a quite simple technique, but it is very useful in privacy-preserving machine learning and data mining. In this paper, we construct an elliptic curve analog of the ElGamal system-based protocol for privacy-preserving frequency mining in fully distributed setting.

  • In this paper, we firstly state the secure three-vector product computation problem and develop protocols called tree-vector products to solve this problem. Our protocols are developed based on some basic protocols and their security properties is validated base on the composition theorem for the semi-honest model [9]. We then use the proposed protocols to address a focus problem of privacy preserving multivariate classification.

  • In this paper, a novel method is presented to detect spam content on the web. It is based on classification and employs an idea from biology, namely, danger theory, to guide the use of different classifiers. The evaluation of content features of WEBSPAM-UK2007 data set using 10-fold cross-validation demonstrates that this method provides high evaluation criteria in detecting web spam.
