Dynamic host configuration protocol (DHCP) authentication using challenge handshake authentication protocol (CHAP) challenge

摘要

A method performed by a Dynamic Host Configuration Protocol (DHCP) server comprising receiving a DHCP DISCOVER message from a DHCP client; generating a challenge in response to the DHCP DISCOVER message; sending the challenge to an authentication device; receiving a first challenge response from the authentication device; generating a DHCP OFFER message; sending the challenge to the DHCP client in the DHCP OFFER message; receiving a DHCP REQUEST message that includes a second challenge response from the DHCP client; comparing the first challenge response with the second challenge response; and authenticating the DHCP client when the first challenge response and the second challenge response match.
