一种自定义动态密钥预防DDoS攻击的算法

A custom dynamic key algorithm to prevent DDoS attacks

DDoS攻击表现形式有多种,主要造成后果是导致Web服务器无法提供网络服务,最终造成一系列损失。针对通过某一网页端口进行的DDosS攻击,提出了一种预防算法,自定义动态密钥,并采用自定义算法调用,动态改变被攻击端口处的文件名。该算法使得攻击者无法通过加密后的文件来得到原文件名称,从而达到预防此种DDoS攻击的目的。实验证明,此算法有效。

DDoS attacks have many manifestation,the main consequences were web server can＇t provide network services, and ultimately cause a series of losses. Aiming at the type of DDoS attacks through a web port,the paper presents a precautionary mea- sure,which custom dynamic key and use custom algorithm to dynamically change the file name in the port attack. The algorithm makes attacker can＇t find the original file name by the encrypted file, then achieves the purpose of the prevention of such DDoS attacks. The simulation shows the validity of the algorithm.
