Mission Statement

The global economy is becoming increasingly dependent on computer networks and particularly the Internet. As a result, networks have inevitably become the target of attackers whose objectives include gaining illegal profits, destroying a country's economy and paralyzing a business competitor's service. To achieve their objectives attackers exploit all possible security holes of the target network, and try to circumvent existing security measures. Our mission is to help address these threats through world-class research and manpower training on network security, and to contribute to the economic growth of Singapore.

 

Major Research Areas

News Flash

  • ACNS'09 (Paris, France) submission due 12/1/2009
  • Recruitment: We are looking for research fellow and software engineer.

Anti-Spam: Spam turns out to be an increasingly serious problem to email users. A number of anti-spam schemes have been proposed and deployed, but the problem has not yet been well addressed. We put forward a practical anti-spam scheme using pre-challenges...

DoS Attacking Defense: DoS/DDoS attacks pose immense threats to the Internet, and consequently many defense mechanisms are being proposed to combat them, from intrusion detection to IP traceback. We are exploring alternative solutions, based on traffic redirection...

Mobile IP Security: Mobile IP technology is useful to improve the convenience on the use of Internet. However, it also introduces new security risks, especially in binding update. We found the IETF standard (RFC 3775) is flawed in its binding update protocol...

Secure Internet Applications: The proliferation of the Internet has provided an efficient and cost-saving platform for running value-added applications such as certified email, contract signing, electronic lottery, and electronic auction, etc. Security is an important factor that cannot be ignored from design to deployment of those applications...

Virtual Private Network: Virtual private network provides protection of confidentiality and authentication at the IP layer. It becomes a cost-effective means for secure communication among distributed organizations. We developed a VPN system supporting the IKE and IPsec protocols, and also identified several security flaws and weaknesses in the IETF standard (RFC 2409)...

Wireless Sensor Network Security: Wireless sensor networks are useful in a variety of domains, and can perform both military and civilian tasks. However, such networks are vulnerable against various attacks, mainly due to resource constraint of low cost sensor motes. We provide SDK for securing wireless sensor networks... new
