Abstract
Embodiments for bounded broadcast encryption key management in a peer-to-peer network are described. To realize bounded broadcast encryption key management, a second peer of the peer-to-peer network receives a first broadcast message from a first peer. The first broadcast message includes at least a public key associated with the first peer. The second peer then generates a key seed in response to receiving the first broadcast message, and creates a second message that includes the key seed encapsulated with the public key. The second peer then transmits the second message to the first peer, and in response to the transmission of the second message, receives a packet from the first peer. The packet includes data encrypted using a secret key derivable from the key seed and one or more portions of the second message.
