Conversely, a hash of the public key does not have this problem: The browser assumes that the child certificate is fixed: It is always the starting point for the certificate chain. A child certificate must carry a signature that is a valid signature from its parent certificate that is specifically iss

Linux 9.0 As the DDNS Server and runs the DNS and DHCP services at the same time. The DNS Server uses Bind 9.2.2, And the DHCP Server uses the DHCP Server v3.0pl2. The following describes how to implement secure and Dynamic DNS in Linux. 　　Create a key To achieve dynamic DNS updates, you must first consider how to ensure secure implementation of DDNS.

virtual machines to simulate DNS spoofing attacks. The tool used is Ettercap. First, let's look at the Target target, Obviously, the IP address directed to www.baidu.com is correct. Then we use ettercap to perform DNS Spoofing. First, find etter. dns configuration file and edit and add A record, direct www.baidu.com to the local IP address to save and exit, use ettercap to start spoofing: Then let's take A look at the attacked Host: as you can see, access to the domain name www.baidu.com on the

fragmentation is hard to process, and DNSSEC and IPv6 are hard to support. Two solutions are proposed. One is that although ENDS0 is expanded, there are few practical applications. The other is to encourage TCP-based DNS, but it may bring about more problems. Other problems include buffer zone poisoning, failure to know root server pollution caused by illegal gTLD and ccTLD, UDP spoofing attacks, and root key management and update problems in
