NERVE Attacks: Breaking AI-Powered Brain-Computer Interfaces
Zahra Tarkhani, Georgios Akkogiounoglou, Lorena Qendro +2
The rapid integration of AI into human-centred systems such as Brain-Computer Interfaces (BCIs) has created a poorly understood attack surface linking neural signals to physical sy…
What if we could hot swap our Biometrics?
Jon Crowcroft, Anil Madhavapeddy, Chris Hicks +2
What if you could really revoke your actual biometric identity, and install a new one, by live rewriting your biological self? We propose some novel mechanisms for hot swapping ide…
Enabling Lightweight Privilege Separation in Applications with MicroGuards
Zahra Tarkhani, Anil Madhavapeddy
Application compartmentalization and privilege separation are our primary weapons against ever-increasing security threats and privacy concerns on connected devices. Despite signif…
Enhancing the Security & Privacy of Wearable Brain-Computer Interfaces
Zahra Tarkhani, Lorena Qendro, Malachy O'Connor Brown +3
Brain computing interfaces (BCI) are used in a plethora of safety/privacy-critical applications, ranging from healthcare to smart communication and control. Wearable BCI setups typ…
Enclave-Aware Compartmentalization and Secure Sharing with Sirius
Zahra Tarkhani, Anil Madhavapeddy
Hardware-assisted trusted execution environments (TEEs) are critical building blocks of many modern applications. However, they have a one-way isolation model that introduces a sem…
