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

Applied Cryptography: Cryptography is the foundation for network security, providing authentication, integrity, non-repudiation, confidentiality and privacy protection. Our research on cryptography is application driven, to address the specific requirements of various applications...

Cloud Computing Security: Cloud computing facilitates deployment of applications without the cost and complexity of buying and managing the underlying hardware and software layers. However, due to security issues, the benefits of cloud computing are not being reaped to their fullest...

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...

Smart Grid Security: Cyber security is one of the key technical areas where the state of the art falls short of meeting the envisioned functionality, reliability and scalability requirements of the smart grid. We are conducting cyber security risk assessment and analyzing the security impact of the impending addition of many IEDs to the existing system...

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...

Recruitment

 

1. Research Scientists

Network Security Group at Institute for Infocomm Research - a national research institute fully funded by the Singapore government, is active in the security community and has established extensive collaborations with local and overseas universities and research institutes.

We are working on a couple of R&D projects and look for research scientists. The candidates should have independent R&D capability and a strong background on network security. The candidates are expected to create valuable intellectual properties, publish papers at leading conferences and journals, and produce project deliverables in time.

Interested candidates please send CV to Jianying Zhou <jyzhou@i2r.a-star.edu.sg>. Fresh PhD is welcome to apply. Review of applications will begin immediately and will continue until the positions are filled. Short-listed candidates will be contacted for interview.

2. Software Engineers

We look for software engineers to develop our security technologies. The candidates must be citizen of Singapore or ASEAN countries, fresh graduate with first-class or second-upper honors, proficient in programming using C and Java, and preferably understanding network security and cryptography.

3. PhD Interns

We also accept PhD interns. The candidate will be attached to our group and do joint research in line with the PhD topic. Allowance will be provided during the attachment.
