A method, apparatus, and system for processing a Dynamic Host Configuration Protocol (DHCP) message are disclosed. The method includes: receiving a DHCP message, where the source address of the DHCP message is a Cryptographically Generated Address (CGA) and a signature of a DHCP message sender is carried in the DHCP message; verifying the CGA and the signature; and processing a payload of the DHCP message after the verification of the CGA and the signature succeeds. The CGA and the signature are verified in the embodiment of the present invention, thus improving the security of DHCPv6, and bringing convenience for key management due to publicity of the public key. In addition, because the life of the public key is long, configuration on the DHCP server and/or the network client is convenient.
