Internet of Things and computer security

Our Internet of Things (IoT) and Computer Security research group explores important issues surrounding the collection and use of often-sensitive Internet-connected data virtually everywhere: its ownership, access and protection.

We regularly collaborate with software and hardware providers, such as Intel AMD  and OpenSSL . We also work closely with Australian defence agencies, including the Defence Science and Technology (DST) Group  and Australian Signals Directorate .  

Our research focuses on:

  • using machine learning algorithms to analyse time-series data on wirelessly powered IoT devices
  • realising security services in the absence of operating-system control, and under device constraints
  • understanding how hardware and operating system services support confidential-information management
  • analysing cryptographic algorithms to identify potential data leaks.
  • Research impact

    Our IoT and Computer Security group aims to provide solutions to fundamental problems in pervasive computing. This includes in relation to:

    • devices’ battery life
    • making sense of noisy, continuous and sometimes untrustworthy data streams
    • authenticating familiar security services and IoT devices’ veracity-sensor measurements
    • securing store keys with limited IoT hardware
    • keeping sensitive information confidential.

    Our research has been applied in a number of real-world settings, including to identify vulnerabilities in commonly used software and hardware, such as Spectre and Meltdown.

    We have also published more papers at top-tier international security conferences than all other Australian research universities combined.

  • Consulting services

    We work closely with industry on IoT deployments that include:

    • machine learning with time series data
    • secure firmware
    • secure firmware updates.
