Abstract
Defending a distributed denial of service attack includes intercepting a service packet sent by the client to a server, according to a rule agreed with the client, obtaining the information carried by a first preset field of the service packet, the inherent information carried by an inherent field of the service packet, and the added information carried by at least one second preset field, according to the hash algorithm agreed with the client, performing a hash processing on the inherent information and at least one added information so as to obtain a hash result, and determining the service packet is discarded when the hash result is different from the information carried by the first preset field.
