Abstract
Early authentication processing uses the manufacture defined ('MD') sequence made available by communication protocols during the Layer 1 training stage of a communications connection process to initiate an authentication request signal. Initiation of an authentication request during the training stage of a communications connection process is accomplished by packaging authentication request information into an authentication request signal and sending the authentication request signal, during the manufacturer defined sequence portion of Layer 1 training, to a communications connection receiver process. The authentication request information typically comprises a username and a password than can be used to verify the identify of the requester. Additionally, processing of an authentication request during the a communications connection process is provided. The processing comprises receiving an authentication request signal, during the manufacturer defined sequence portion of Layer 1 training, from a communications connection sender process and initiating authentication based upon the authentication request signal. Acknowledgment signals can be sent between the initiator and receiver such that each can be assured that the other received the appropriate information.
