On Privacy Losses in the Trusted Agent Model (Abstract)

Serge Vaudenay

Tamper-proof devices are pretty powerful. They typically make security applications simpler (provided that the tamper-proof assumption is not violated). For application requiring privacy, we observe that some properties may become harder (if possible at al ...

On Tamper-Resistance from a Theoretical Viewpoint: The Power of Seals

Serge Vaudenay

Tamper-proof devices are pretty powerful. They can be used to have better security in applications. In this work we observe that they can also be maliciously used in order to defeat some common privacy protection mechanisms. We propose the theoretical mode ...
