Linux IPv6环境下DNS服务器配置攻略 （2）

 

中国IT实验室收集整理

    Dnssec配置命令：

        dnssec-keygen -a DSA -b 768 -n ZONE secv6.your.domain
        dnssec-signzone -o secv6.your.domain secv6.your.domain

        说明：DNSSEC主要依靠公钥技术对于包含在DNS中的信息创建密码签名。密码签名通过计算出一个密码hash数来提供DNS中数据的完整性，并将该hash 数封装进行保护。私/公钥对中的私钥用来封装hash数，然后可以用公钥把hash数译出来。如果这个译出的hash值匹配接收者刚刚计算出来的hash树，那么表明数据是完整的。不管译出来的hash数和计算出来的hash数是否匹配，对于密码签名这种认证方式都是绝对正确的，因为公钥仅仅用于解密合法的hash数，所以只有拥有私钥的拥有者可以加密这些信息。
