ABSTRACT:
Embodiments of the application describe a method and system for discovering and authenticating communication devices and establishing a secure communication link within a wireless home network without requiring a secure channel. According to an embodiment, communication devices exchange public keys using multiple messages each including at least a portion of the public key of the sending device. The devices authenticate the receipt of the public key and establish a shared master key. The shared master key is used to further derive a session key for securing the application data between the communicating devices for a current session.
