The RELOAD (REsource LOcation And Discovery) overlay provides a distributed data store for publishing and retrieving resources for use in a P2PSIP environment. It is based on a DHT (Distributed Hashtable) using centrally signed certificates to provide authentication among peers.  Each entry in the DHT may typically only be written by peers who can present a certificate for a name matching the ID of the resource to be written. This strict access control policy constitutes a problem for registering shared resources, e.g. for use in a distributed conference.

The presentation will give an overview of RELOAD, with a focus on security concepts. Further, a lightweight approach will be presented for delegating write permission for a specific resource to a group of peers.
