Claim:
A method for strong access control to a network, the method comprising the following steps: (a) coupling an authentication device to a network; (b) transmitting an initial response; (c) generating a network response upon receipt of the initial response; (d) comparing the initial response and the network response; (e) authenticating the authentication device if the initial response and network response match, and not authenticating the authentication device if the initial response and network response do not match; (f) providing access to network resources upon authentication of the authentication device; (g) transmitting a subsequent response for accessing subsequent network resources; (h) comparing the subsequent response to a subsequent network response; (i) authenticating the authentication device if the subsequent response and subsequent network response match, and not authenticating the authentication device if the subsequent response and subsequent network do not match; and (j) providing access to subsequent network resources upon authentication of the authentication device.
