VIRTUAL CloudX -- Main Stage

Alok Ranjan, Dropbox, Software Engineering Manager

As enterprise security requirements intensify, empowering users with full control over encryption becomes paramount. In this session, I’ll reveal how Dropbox pioneers user-controlled encryption at exabyte scale with an innovative three-tiered scheme using AWS KMS. We’ll discuss how our approach grants teams complete control via Team Encryption Keys (TEKs) secured by Hardware Security Modules (HSMs), while an intermediate layer of Namespace Encryption Keys (NEKs) ensures rapid, secure file sharing—even across teams. Learn how practical strategies like key caching and efficient key rotation maintain exceptional performance and data integrity through a robust key chain of custody. This talk is ideal for professionals keen on leveraging AWS technologies to enhance security and scalability in cloud storage solutions.
