摘要

CP (Cache Poisoning)攻击是DNS中主要的安全威胁之一，攻击者可以改变响应报文中的IP地址或DNS中的数据库。为了解决CP攻击，已经提出了许多安全协议。与基于移位键的方法相比，本文提出了字符加密(CWE)方法，以提供更好的针对CP攻击的安全性(成功攻击的概率低至10−33)。此外，该方法还缩短了加密时间。例如，当域名长度为30时，与基于shift-key的方法相比，CWE可以减少10.7%的加密时间。

An Encryption Algorithm to Prevent Domain Name System Cache Poisoning Attacks

One of the major security threats in domain name system (DNS) is Cache Poisoning (CP) attack, where an attacker can change the IP address in the response packet or the database in DNS. To address CP attacks, many security protocols have been proposed. This paper proposes character-wise encryption (CWE) method to provide better security against CP attacks (the probability of successful attack is low as 10−33) as compared to the shift-key based method. In addition, the proposed method results in shorter encryption time. For example, with a domain name length of 30, CWE can reduce the encryption time by 10.7% as compared to the shift-key based method.
