Ladon

Traditional backup methods in a home or small office
environment are complex and insecure. They allow
modification of the data without
the knowledge of the owner unless additional steps
are taken to secure a hash of the media.
Additionally, if a backup is tampered with there is
no way to revert to the non-tampered with state of
the backup unless additional work has also gone into
creating multiple backups, and then there is the
additional problem of verifying all of the backups
periodically. To solve these problems, we developed
Ladon, a framework for distributed backups. Ladon
operates in a peer-to-peer fashion and assumes
malicious remote peers. Ladon''s purpose is to
securely store data across a heterogeneous
environment of networked desktop computers. Ladon
uses algebraic signatures to allow third parties to
verify data without possessing a copy of the data,
which prevents malicious peers from destabilizing the
system. We have designed our system for use in medium
bandwidth environments such as home broadband DSL or
cable.
