Abstract
A client connected to a network switch is continuously authenticated to a network switch by using biometrics, wherein the client and the network switch exchange Ethernet/802.3 frames associated with a client application, and wherein the client and the network switch are coupled by a full-duplex Ethernet/802.3 communication channel. A biometric data sample of a user of the client is captured. Biometric data is encapsulated in an authentication protocol message frame. The authentication protocol message frame is separated into a sequence of a plurality of fragments, each fragment having a predetermined number of bytes. Respective sequence numbers are assigned to each of the fragments. Each of the fragments is inserted with its respective sequence number in a respective preamble of a respective one of a plurality of Ethernet/802.3 frames associated with the client application that are being transmitted from the client to the network switch.
