ePrint Report: Efficient Secure Storage with Version Control and Key Rotation

Long Chen, Hui Guo, Ya-Nan Li, Qiang Tang

Periodic key rotation is a widely used technique to enhance key compromise resilience. Updatable encryption (UE) schemes provide an efficient approach to key rotation, ensuring post-compromise security for both confidentiality and integrity. However, these UE techniques cannot be directly applied to frequently updated databases due to the risk of a malicious server inducing the client to accept an outdated version of …
