It's difficult to ensure that data has been completely deleted,
especially if it must be robustly available before it expires.
To be robustly recoverable, there must be copies on backup
media,
stored in many different locations. It would be infeasible to
ensure that all copies of a file get deleted. The basic solution
is to encrypt the data, store it in encrypted form, and then
throw away the key. This talk describes a system that
centralizes
the expense and expertise of key management, but in a way with
minimal trust in the key managers, so that key management and
storage can both be outsourced. This talk describes how to do
time-based deletion (where the expiration time of the file is
declared when the file is created), and on-demand delete (where
an individual file is deleted without prior plan of deletion
time).

Radia Perlman is a Distinguished Engineer at Sun Microsystems.
She is known for her contributions to bridging (spanning tree
algorithm) and routing (link state distribution) as well as
security (sabotage-proof networks).

She is the author of the textbook Interconnections: Bridges and
Routers, and co-author of Network Security: Private
Communication
in a Public World, two of the top 10 Networking reference books,
according to Network Magazine.

Dr. Perlman is one of the networking industry's 25 most
influential people, according to Data Communications Magazine.
She has about 50 issued patents in the fields of routing and
security. She has a PhD in computer science, degrees in
mathematics from MIT, and an honorary doctorate from the Royal
Institute of Technology in Sweden.
