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
