FrozenCache examines #days Security & Risk Conference: Jürgen Pabel.

Summary

Jürgen Pabel explains cold boot attacks where RAM retains full-disk encryption keys after power-off and proposes FrozenCache, storing keys in CPU cache via cache-as-RAM mode so they are not in removable RAM. Demonstrates a Linux kernel module integrating with DM-Crypt, noting severe performance degradation in the early prototype.
