ABSTRACT:
A method for key agreement for a cryptographically secured point-to-multipoint connection between a server and a plurality of clients includes altering, as a function of an identifier included in a first server message, a sequence of messages in a handshake initiating a secure socket layer protocol session. The identifier identifies the connection as an IP multicast connection. A MasterKey is generated using the server, the MasterKey being used to generate a session key for encrypting application data. The MasterKey is transmitted to the client.
