A retention-aware system turns a computer's storage chip into a cybersecurity shield

Weidong Zhu developed a retention-aware system with University of Florida collaborators that extends data survival on storage chips after computer compromise. The system prolongs file persistence in the critical window following a security breach. The work is published in the Proceedings of the 2025 ACM SIGSAC Conference on Computer and Communications Security. Data on storage chips remains accessible longer when attacked. This enables defenders to detect and respond to breaches more effectively. The system operates at the hardware level without requiring software updates.
