Abstract
In a typical peer-to-peer network, any user of the peer-to-peer network may request a lookup of a key and its associated value. To limit access to a stored key-value pair, a user node may generate a registration message for a key-value pair. The value may include the payload to be stored at the storage node, and an access list containing one or more retrieval identifiers indicating one or more users authorized to access the payload. In some cases, the registration message may also include an encrypted payload which is encrypted with a group key. The group key may be included in the registration message, and may be encrypted with an encryption key which is known by the authorized user.
