Productivity and Innovation - Wireless Security

Productivity and Innovation

In the Faculty of IT, research in the emerging area of Wireless Security is led by Professor Bala Srinivasan, Dr Phu Dung Le, and Dr Nandita Bhattacharjee.

Our researchers are currently engaged in the following projects addressing this research theme:

Authentication Model for Wireless Network Services

Researchers: Prof Bala Srinivasan, Dr Phu Dung Le and Mr Harry Huy Hoang Ngo
Centre: DSSE
Project outline: Authentication is the process in which a client tries to prove its identity. Authentication in a wireless network is a big challenge due to eavesdropping and intercepting attacks, network bandwidth and latency variations, resource constraints of mobile devices, and mobility of users. more...
Therefore, many types of attacks on authentication are possible. This project is investigating the risks on previous authentication approaches to propose a new model which can prevent unauthorized access that can be secure under security attacks and work efficiently on wireless networks. less...

Security Architecture for Sensitive Information Systems

Researchers: Prof Bala Srinivasan, Dr Phu Dung Le and Mr Xianping Wu
Centre: DSSE
Project outline: Protecting sensitive information is a growing concern around the globe. The importance of securing critical data in business, bank, healthcare and military has reached the first priority of sensitive information management. more...
Failure to protect these assets would result in high cost and, more importantly, can also result in lost customers, investor confidence and even threats of national security.
Therefore, this project aims to investigate the major security issues in current information systems, analyse their problems. Then develop novel generic security architecture for sensitive information system. less...
Key outcomes:  

Internet Payment Systems Security

Researchers: Prof Bala Srinivasan, Dr Phu Dung Le and Mr Osama Dandash
Centre: DSSE
Project outline: Nowadays, preventing Fraud is a growing concern around the globe. The indecent deployment of security operations such as authentication and access control as well as the lack of sufficient secure architecture of existing payment systems has led to the lack of important transaction security properties. more...

This is one of the major causes of illegitimate Internet payments.
Therefore, the aim of this research is to investigate the major security issues in current Internet payment systems, analyse their problems. Then propose a new Multiple Authentication System to prevent illegitimate users from performing fraudulent Internet payments. less...

Biometrics for Wireless Security

Researchers: Prof. Bala Srinivasan, Dr Nandita Bhattacharjee
Centre: DSSE
Project outline: Biometrics has the potential to identify individuals, as it cannot be forged, duplicated or shared among users. Biometric systems are widely used for reliable user authentication. more...
These systems will proliferate into the core information infrastructure of the (near) future. When this happens, it is crucial that biometric authentication is secure.
Two critical issues with biometric systems are the storage of templates in a database due to privacy concerns and the presence of noise in a biometric template making it unreliable. Error correction coding using a fuzzy vault scheme is one of the most comprehensive mechanisms for secure biometric authentication It can then be applied to applications like secure e-commerce, enabling secure online business activities such as direct selling, online banking, billing and payment systems, access control, immigration, public safety, national identity, etc. Credit card payment systems using a biometric key for securing cryptographic operations between a client and a bank server can be a very common application. This equipment will be used for the development of error tolerant techniques for biometrics in security.
Currently we have a PhD student working on the error correcting codes for iris biometric and 4 other Masters Honours students working in this area of biometrics. The project will facilitate the generation of iris codes from databases of eye images and also provide a platform for further research in biometric authentication and identification systems for secure applications. less...

Deploying Mobile Software Agents on Wireless Sensor Networks

Researchers: Ms Ranjani Nagarajan and Dr Mohamed Medhat Gaber
Centre: DSSE
Project outline: Mobile software agent paradigm provides a cost efficient way for application deployment in wireless sensor networks. more...
The deployment of mobile software agents on wireless sensor networks has been studied using two commonly used sensor platforms, namely, Crossbow Mica2 motes and Sun SPOT. It was found that the Sun SPOT environment does not support mobile software agents due to the absence of the serializable interface. Agilla platform has been used as the second choice after researching different alternatives. Agilla was found to be supportive to developing mobile software agents in wireless sensor networks. less...
