Equipment for preventing IPv6 address counterfeit denial of service attack and transmission method

The invention provides equipment for preventing IPv6 address counterfeit denial of service attack and a transmission method, which are used for solving the problems that the existing technology for preventing the IPv6 address counterfeit attack lacks neighbor broadcast information message inspection, so that a host is easy to suffer from the denial of service attack; the flood attack of an attacker cannot be prevented by setting a fixed number of repeated detection times, and the method belongs to the technical field of network security. According to the method, the flag bit and the option field are added in the neighbor request information message and the neighbor broadcast information message, and the CRC32 function is used for calculation and verification, so that the authenticity of the message and the uniqueness of the address are detected, and an illegal user is effectively prevented from attacking by counterfeiting an IP address. 本发明提出一种防止IPv6地址仿冒拒绝服务攻击的设备及传输方法，用于解决现有防IPV6地址仿冒攻击技术中缺乏邻居广播消息报文检验，容易使主机遭受拒
