We have been exploring solutions for data security, considering potentially dangerous but realistic situations — e.g., physical attacks when the attacker has full control over the target machine and can coerce the machine owner into revealing encryption passwords. We believe such a strong attacker model is in accordance with current state-level adversaries with high technical capabilities and legal/questionable/illegal powers (e.g., US FISA, clandestine NSA programs, physical/psychological tortures). I will discuss two recent proposals: Gracewipe (coercion-resistant disk data deletion) and Hypnoguard (cold-boot protection for RAM data in sleep). While our solutions are possibly a step forward, more importantly, we highlight pitfalls of such solutions against a strong adversary. Details of these systems are available at:
