The principal objective of the project is to analyze vulnerabilities and develop mechanisms to provide secure and reliable networks using wireless communications. A particular focus is on securing dynamic and large scale distributed ad hoc networks which have significance in both civilian and military applications. For instance, we will consider the latest development in the research of elliptic curves cryptography (ECC) and identity-based encryption and signature schemes (IBE/IBS) to provide security services. Other services may base upon the provided secure reliable wireless communication platform. The project will strengthen the ability of individuals and companies to protect their information over the open air transmission. The research will be an interaction between issues in security, privacy protection and vulnerability and issues in communication technology and infrastructure.

Sub goals

  • Design authentication, key-exchange, secure routing protocols that in an efficient way may secure ubiquitous computing environments, like wireless or mobile ad hoc communication, using the recent advancement in the research of elliptic curves cryptosystem and identity-based cryptosystem;
  • Design user mobility and service continuity mechanisms across heterogeneous wireless networks, that involve session continuity across multiple Access Points (APs) in WLANs and WiMAX networks, seamless roaming and secure service between 2G/3G cellular systems and WLANs and WiMAX networks;
  • Provide reliable communications in mobile ad hoc networks that involves topology control and connectivity algorithms, reliable data transmission over multiple hops in distributed ad hoc networks, and novel MAC protocols for multi-path communications in wireless networks;
  • Provide QoS frameworks and resource management mechanisms in wireless networks that involve cross-layer QoS design for wireless channels, and QoS enhancements to IEEE 802.11-based WLANs and IEEE 802.16-based WiMAX networks;
  • Develop a demonstrator for secure and reliable multi-hop voice and data communications based on PDAs or laptops;
  • Raise public awareness on the security issues in wireless communications.

Work packages

WP1: Secure wireless and ad hoc communication

The work package will focus on security and reliability, with three main objectives:

  • Identify cryptographic mechanisms and protocols that are applicable to wireless and especially ad hoc networking;
  • Design security architecture suitable for use in wireless and ad hoc networking;
  • Simulate and possibly implement the proposed mechanisms and architecture.

WP2: User mobility and services continuity

The work package will focus on service continuity, covering both Mobile IP and SIP-based architectures. The following outcome is expected:

  • Enhancement mechanisms for user authentication in wireless networks;
  • Mechanisms for seamless user access through SIM authentication in 802.11 WLANs and 802.16 WiMAX networks;
  • Interworking of SIM based authentication between personal devices, based on local communication, i.e. Near Field Communication and/or Bluetooth;
  • Mechanisms to keep session continuity with QoS insurance while users are moving across multiple APs in WLANs and WiMAX networks;
  • Mechanisms for secure service roaming between 2G/3G/4G mobile networks and WLANs and WiMAX networks.

WP3: Reliable communications in mobile ad hoc networks

This work package concentrates on reliable communications, and plans to deliver:

  • Theoretical study on topology control and network connectivity for distributed mobile ad hoc network;
  • Algorithms for reliable and optimal path selection in the presence of multiple channels in wireless ad hoc networks;
  • MAC layer algorithms/mechanisms for QoS enhancements to existing IEEE 802.11-based WLANs and 802.16 WiMAX networks;
  • Radio resource management and scheduling considering the dynamics of radio channels;
  • A prototype demonstrator for reliable multi-hop ad hoc communications.
