Abstract: A method is provided for establishing a communication session in a communications system. The method includes providing a handshake layer functional block in a first communication peer, and providing a data communication layer functional block separate from the handshake layer functional block in the first communication peer. Functionality of the data communication layer is not duplicated in the handshake layer. If the data communication layer is unable to process a received encrypted message; transmitting, by the data communication layer, a configuration request message to the handshake layer, and transmitting, by the handshake layer, in response to the configuration request message, a set channel state message to enable the data communication layer to process application data after a handshake phase of the protocol session is complete. Then, application data can be communicated through the data communication layer functional block of the first communication peer to a second communication peer.

Abstract: A method is provided for establishing a secure communication session in a communication system. The method includes providing a handshake layer functional block and providing a record layer functional block separate from the handshake layer functional block. Functionality of the record layer functional block is not duplicated in the handshake layer functional block. The record layer functional block of a first communication peer generates an ephemeral key pair. A public key of the ephemeral key pair is transmitted to the handshake layer functional block of a second communication peer via the handshake layer functional block of the first communication peer. A session key is generated from the public key of the second communication peer and a private key of the first communication peer. Messages communicated between the first communication peer and the second communication peer are protected using the session key.

Abstract: A method is provided for establishing a secure communication session in a communications system. The method includes providing a handshake layer functional block and providing a record layer functional block separate from the handshake layer functional block. A first ephemeral key pair is generated by the record layer functional block of a first communication peer. A public key of the first ephemeral key pair is transmitted to a second communication peer. The handshake layer functional block of the first communication peer generates a second ephemeral key pair. A public key of the second ephemeral key pair is transmitted to the second communication peer. The second communication peer generates a third ephemeral key pair. A handshake key is generated from the public key of the second communication peer and a private key of the handshake layer block of the first communication peer. A session key is generated from the public key of the second communication peer and a private key of the record layer block of the first communication peer
