Brilliant and scary new paper from @kientuong114 and @jonas__hofmann to appear at ACM CCS 2024 - they analysed multiple "zero knowledge" E2EE cloud storage vendors' products and found major holes in their crypto architectures. "A broken ecosystem" indeed.

馃搫 End-to-end Encrypted Cloud Storage in the Wild: A Broken Ecosystem (To appear at ACM CCS 2024)

Joint work with @jonas__hofmann.

We analyzed five end-to-end encrypted cloud storage services and found severe vulnerabilities in four of them.

A Formal Treatment of End-to-End Encrypted Cloud Storage (Crypto'24): in this new paper we designed an E2EE cloud storage protocol and prove it secure in novel game-based confidentiality and integrity notions that capture real-world complexities and malicious servers.
