As part of a broader organisational restructure, data networking research at Swinburne University of Technology has moved from the Centre for Advanced Internet Architecture (CAIA) to the Internet For Things (I4T) Research Lab.

Although CAIA no longer exists, this website reflects CAIA's activities and outputs between March 2002 and February 2017, and is being maintained as a service to the broader data networking research community.

Lawful Interception For Everyone(LIFE)


Lawful Interception is a fact of network life. Whether we like it or not, Internet Service Providers will soon be facing the same legal obligations regarding Lawful Interception as the Telecommunications Carriers have faced for decades. Those of us working on network technologies and applications can no longer ignore it in the hope that it will go away. It won't.

However, acceptance of the reality of Lawful Interception doesn't mean we should accept without question the obligations the regulators place upon us. Solutions for Internet Lawful Interception need to supply the Law Enforcement Agencies with whatever they are entitled to, but no more. Research is needed into developing solutions that are robust, parsimonious in what they deliver to the Law Enforcement Agencies and are well understood.

If done badly, Lawful Interception is a great threat to network security and so should be thoroughly researched and understood. 'Security by obscurity' is a bad idea here as elsewhere.

LIFE aims to develop techniques for Lawful Interception that meet the above criteria. Lawful Interception Future Environments is about investigating interception techniques that are open to scrutiny by anyone who is interested.

Research Focus

LIFE focuses on three areas:

  • Robust and secure techniques for Lawful Interception requiring minimal introduction of new hardware
  • Lawful Interception of emerging networks and technologies;
  • Techniques for harmonizing access network and IP network Lawful Interception obligations.

As part of this project we will develop and release prototypes to assist in trialling and understanding new techniques. The links below will take you to additional information.
