Breaking and Fixing Length Leakage in Content-Defined Chunking

This talk from Real World Crypto (RWC) 2025 explores the vulnerabilities and solutions related to length leakage in content-defined chunking systems. Presented by Kien Tuong Truong and Matteo Scarlata as part of the Secure Cloud & File Storage session chaired by Matthew Campagna, the presentation delves into how attackers can exploit information leaked through chunk lengths and proposes countermeasures to mitigate these security risks. Learn about the technical challenges in secure file storage systems and how researchers are addressing these critical privacy concerns in modern cloud storage architectures.
