基于IPv6的链路目的地址伪造报文攻击安全性研究

With the popularization and application of IPv6 network, people pay more attention to the safety of IPv6 network. The attack based on the forged links address is a major danger of IPv4 network security. Analysis and research of the IPV4 and IPV6 packet attack based on the forged link destination address, we respectively simulated and tested the address of nodes forged by an attacker, the neighbor request information carrying false addresses of the source link layer and the neighbor declared information with false addresses of the destination link layer, which can monitor whether the recipient updated the neighbor caches and storage the wrong link layer addresses which will cause the legal packets cannot be sent to the attacked nodes. The results of our tests indicates that IPV6 network improved the security of network in preventing the attack through the neighbor request information carrying false address of the source link layer and the neighbor declared information with false address of the destination link layer from the address of nodes forged by an attacker.
