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 register a key-value pair in a peer-to-peer network associated with an access list listing those user nodes which are authorized to access the key-value pair. The access list may include one or more retrieval identifiers. To further secure the information, the retrieval identifiers and/or the payload may be encrypted. To allow the retrieving user to decrypt an encrypted payload, the payload may be encrypted using a group key associated with the stored key-value pair. The group key may be encrypted using a key known to the retrieving user.
