Version control systems are widely used in software development and document management. Unfortunately, versioning confidential files is not normally supported: Existing solutions encrypt the transport channel, but store data in plaintext within a repository. We come up with an access control solution that allows secure versioning of confidential files even in the presence of a malicious server administrator. Using convergent encryption as a building block, we enable space-efficient storage of… CONTINUE READING
