The Authentication Suboption for the Dynamic Host Configuration Protocol (DHCP) Relay Agent Option
The Dynamic Host Configuration Protocol (DHCP) Relay Agent Information Option (RFC 3046) conveys information between a DHCP Relay Agent and a DHCP server. This specification defines an authentication suboption for that option, containing a keyed hash in its payload. The suboption supports data integrity and replay protection for relayed DHCP messages.
