Abstract
We propose a simple scheme, based on secret sharing over large-scale networks, for assuring
recoverability of sensitive archived data(e.g., cryptographic keys). In our model anyone
can request a copy of the archived data but it is very difficult to keep the existence
of a request secret or to subvert the access policy of the data "owner". We sketch an
architecture for such a system that might be suitable for deplyment over very large-scale
networks such as the Internet.
