Problems solved by technology

But this method also has a fatal loophole, that is, if the source code of the authentication algorithm that plays a key role in it is leaked, the entire authentication mechanism will also collapse.

Abstract

The invention discloses a CC (Challenge Collapsar) attack processing method and device. The method comprises the following steps: sending a service request to a target host according to a relevant control instruction, so that the target host returns a preset initial value and a preset submission condition to a CC attack end according to the service request; performing an iterative loop operation on the initial value by using a preset built-in algorithm until a final operation result that meets the submission condition is obtained; and sending the final operation result to the target host, so that the target host returns an access permission instruction to the CC attack end according to the final operation result. According to the CC attack processing method provided by the invention, by increasing the operation pressure of the CC attack end, the CC attack end cannot calculate a large number of legal return values in a short time, so that a large number of attacks cannot be initiated within a short time, thus the threat of the attacks is directly eliminated at a source end.

Description

technical field [0001] The present invention relates to the technical field of human network communication, in particular to a CC attack processing method and device. Background technique [0002] The attacker uses the proxy server to generate a legitimate request directed to the victim host to achieve DDOS and camouflage called: CC (Challenge Collapsar), and we call such an attack a CC attack. [0003] CC attacks are generally used to attack some WEB interfaces. In a normal communication, the following three steps are generally involved: the client initiates a request, the server receives and processes the request, and the server returns the processed result. However, some requests consume a lot of server resources, that is, after receiving such requests, the server needs to perform a lot of calculations to calculate the results that need to be returned. Normal request speed, the resource consumption caused by the server processing these requests is within the processing ...
