Abstract
The Paranoid file system is an encrypted, secure, global file system with user-managed access control. The system provides efficient peer-to-peer applicationtransparent file sharing. This paper presents the design, implementation and evaluation of the Paranoid file system and its access-control architecture. The system lets users grant safe, selective, unix-like, file access to peer-groups across administrative boundaries. Files are kept encrypted and access control translates into key management. The system uses a novel transformation key scheme to effect access revocation. The file system works seamlessly with existing applications through the use of interposition agents [18]. The interposition agents provide a layer of indirection making it possible to implement transparent remote file access and data encryption/decryption without any OS modifications. System performance evaluations show that encryption and remote file-access overheads are small, showing that the Paranoid system is practical. 1
