Prof. Vijay Varadharajan from the Faculty of Engineering and Built Environment at The University of Newcastle has completed the report for one of the grants that was allocated for implementation in 2018, titled “Software Defined Networks based Security Architecture for IoT Infrastructures”.
The project developed fine granular security policies and a lightweight security protocol to authenticate IoT devices and authorise them to access services in network infrastructure in a secure manner. The project involved three stages:
- In the first stage, the project team conducted a detailed study of security attacks on IoT infrastructures and the different security solutions that currently exist to counteract the various types of attacks. Then, analysed the pros and cons of the existing solutions, and developed security requirements that need to be addressed in designing security architecture for IoT Applications.
- As part of second stage, the team developed a lightweight authentication protocol based on a novel public key encryption scheme. The proposed protocol achieved a balance between the efficiency and communication cost without sacrificing security.
- In the third stage, the team proposed a SDN based security architecture for IoT systems. Their security architecture allowed specification of fine granular access policy constraints on communications between end users, devices and services in a distributed environment. A novel feature of the proposed architecture is its ability to specify path based security policies, which is a distinct advantage in SDNs.

Sylvia Cadena - ISIF Asia secretariat
After ten years managing the Information Society Innovation Fund (ISIF) at APNIC, Sylvia was appointed Head of Programs at the APNIC Foundation in December 2016. As Head of Programs, Sylvia works on the management, design and implementation of collaborative programs to expand APNIC’s capacity building efforts and its overall Development Program.
At ISIF Asia, Sylvia continues to lead a grants and awards program that seeks to empower communities in the Asia Pacific to research, design and implement Internet-based solutions for their own needs. One of the region’s most established Internet development programs, ISIF places particular emphasis on the positive role the Internet has on social and economic development in the Asia Pacific.
Sylvia also leads APNIC’s engagement with the Seed Alliance, a global collaboration with the African (AFRINIC) and South American (LACNIC) Internet registries. Together with its funding partners, and various regional sponsors, the Seed Alliance supports innovative Internet development across the global south. She is also a member of the ICANN CCWG on new gTLD auction proceeds and co-chair of the APrIGF.
Throughout her career, Sylvia has focused on the strategic use of the Internet for development with an emphasis on capacity building. Since her early years as a UN Volunteer, she has worked across the multi-stakeholder spectrum of organizations with technical and advisory roles, mainly about information systems, access provision and innovation.
In July 2003, her work was recognized with the "Annual Award for Young Professionals" by the International Development Research Center (IDRC).
