Abstract

The embodiment of the invention provides a method of increasing the safety of the address conflict detection process. The method comprises the following steps: when a host in a subnet performs a conflict detection, a neutral server receives the duplication address detection (DAD) information sent from the host; the neutral server records the updated DAD information, performs a conflict judgment according to the currently used address information and sends an address conflict notice; the host in the subnet sends an address resolution message during the address resolution process, and the neutral server judges whether the IP address of the host is legal according to the local address information. In the scheme provided by the invention, the neutral server is added in the subnet so as to solve the possible security threats of address conflict concealment, address conflict misrepresentation, ARP deception and the like during the stateless address autoconfiguration process of the Ipv6 network, and increasing the safety of the address conflict detection process.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular, the invention relates to a method for improving the security of an address conflict detection process. Background technique [0002] As the crisis of address space exhaustion under the IPv4 protocol gradually intensifies, the IPv6 protocol, which can provide a larger address space in the most direct way and solve the problem of address space exhaustion under the IPv4 protocol, has emerged as the times require. The available addresses under the IPv6 protocol are theoretically 2^96 times that of IPv4, and such a huge difference in the number of addresses also determines that the address allocation method under the IPv6 protocol must have different characteristics from IPv4. [0003] The IPv6 protocol is the core protocol of the next-generation Internet. It solves many defects exposed by the IPv4 protocol, such as scarcity of addresses, huge routing tables, and insufficient suppo...
