DNSSEC是域名系统（DNS）的一项功能，用于验证对域名查找的响应。它可以防止攻击者操纵或毒害对DNS请求的响应。DNS技术的设计没有考虑到安全性。对DNS基础架构的攻击的一个示例是DNS欺骗。在这种情况下，攻击者会劫持DNS解析程序的缓存，导致访问网站的用户接收到错误的IP地址，并查看攻击者的恶意站点，而不是他们想要的站点。
When you activate DNSSEC, we'll generate a public-private key pair for your zone. The public key, provided as DS or DNSKEY records, should be configured with your domain provider. Our network will use the private key to sign your records during zone deployment. The end-user resolver checks these signatures against the public keys to authenticate record integrity during transfer.
DNSSEC aims to enhance user safety by verifying digital signatures after a user enters a domain name. Information can only reach the user's device when digital signatures match between the data and the Primary DNS server, ensuring connection to a legitimate website. It utilizes digital signatures and public keys to validate information, adding new records to existing DNS entries like A, CNAME, and MX. DNSKEY and RRSIG digitally sign DNS data using public-key cryptography. Each DNS zone's name server holds public and private keys. When a user queries, the server provides information signed with its private key, which the recipient opens with the public key. If information is modified, it won't open correctly, triggering an error message.

只需单击控制面板中的激活按钮，我们的系统就会保护该区域。只需在提供程序中添加DS记录，即可完成安装。
我们对所有签名使用椭圆曲线算法（ECDSA P-256），该算法比标准RSA密钥更强、更小。
保持DNS答案尽可能小意味着更快的速度！此外，我们的Anycast DNS网络可以从距离解析器最近的位置提供更快速的响应。
无论哪一天，无论何时，我们都能提供连续不间断的网络监控和支持。 我们的技术支持团队通过实时聊天和工单为您提供24/7在线服务。您可以免费迁移您的区域，在这里了解更多.
To activate DNSSEC signing and obtain the domain DS records and DNSKEY records, you need to process the following steps:
Optional: For additional details and guidance about DNSSEC implementation, refer to the ClouDNS DNSSEC wiki page.
When you want to connect to a particular website, your browser should get the corresponding IP address. Unfortunately, there is a chance an attacker to intercept your DNS queries and place fake information. As a result, your browser will connect to a forged website where you could potentially enter personal information, like bank details.
Thanks to DNSSEC, there is an additional level of security, and your browser is able to check if the DNS data is actually correct and not changed. In addition, DNSSEC is used not only for the web but also by any other Internet service or protocol, for instance, SMTP and Voice-over- IP (VoIP).
DNSSEC验证是一个简单的过程，包括以下步骤：
