<p>Dynamic host configuration protocol (DHCP) is extended in order to assist with secure network location awareness. In an embodiment a DHCP client receives a signed DHCP response message from a DHCP server, the signed message comprising at least a certificate chain having a public key. In that embodiment the DHCP client validates the certificate chain and verifies the signature of the signed message. If this is successful the DHCP client accesses stored settings for use with the server. The stored settings are accessed at least using information about the public key. In some embodiments signed DHCPOFFER messages and signed DHCPACK messages are used. In another embodiment the signed DHCP message comprises a location identifier which is, for example, a domain name system (DNS) suffix of a DHCP server.</p> |
