Tahoe-LAFS (Tahoe Least-Authority File System)

Contributor(s): Kim Hefner

Tahoe-LAFS (Tahoe Least-Authority File System) is a distributed storage system that offers provider-independent security for local or cloud storage.

Once information is encrypted using the Tahoe-LAFS open source cloud storage option, the data is sent to storage devices and striped across multiple cloud storage providers. The cloud storage providers are unable to read or modify user data because mathematics computed on the client side guarantee file integrity and confidentiality. Security is improved because providers store only fragments of data, while data storage redundancy is achieved through erasure coding rather than replication.
