Abstract

The invention discloses a data processing method and device, relates to the field of communication, and solves the problem of how to quickly distinguish legal traffic from illegal traffic when DDoS attacks are defended. The method comprises the steps that a verifiable identifier and a secret key corresponding to the verifiable identifier are allocated to a terminal accessing a service supported torun by an application server, and the terminal carries the verifiable identifier and a verification code in a sent data packet, therefore, network equipment can identify the legal data packet and theillegal data packet according to the verifiable identifier and the verification code and forward the legal data packet.

Description

technical field [0001] The present application relates to the communication field, and in particular to a data processing method and device. Background technique [0002] At present, the distributed denial of service (Distributed Denial of Service, DDoS) attack is still a major factor that destroys network availability and causes network security problems. In traditional technologies, black hole technology or traffic cleaning technology is usually used to defend against DDoS attacks. However, network devices use black hole technology to direct both illegal traffic and legal traffic to the black hole, making it impossible to distinguish legal traffic from illegal traffic. Although network devices can distinguish legal traffic from illegal traffic by using traffic cleaning technology, it takes a long time to distinguish legal traffic from illegal traffic. Therefore, how to quickly distinguish legal traffic from illegal traffic when defending against DDoS attacks is an urgent...
