IPv6 (Internet Protocol Version 6) network node identity security protecting method

Abstract

The invention discloses an IPv6 (Internet Protocol Version 6) network node identity security protecting method, which comprises the following steps: injecting a group of keys K1 into an initial network entry router of a node A and the node A, and storing, by the node A, a unicast IP address of the initial network entry router; acquiring, by the node A, a temporary sub-net IP address; sending, by the node A, an Internet access request message to a sub-net I router by using the temporary sub-net IP address; acquiring, by the sub-net I router, the key K1 of the initial network entry router; encrypting, by the sub-net I router, a unique PIN code of the sub-net I router and a random number by adopting the key K1, and feeding back to the node A; and decrypting, by the node A, the encrypted cyphertext X by adopting the key K1, and calculating the decrypted correct PIN code, the random number and an MAC (Multi-Access Control) address of the node A to acquire an interface identifier of a globalunicast IP address. According to the IPv6 network node identity security protecting method, the latter 64-bit address of the IPv6 unicast address of the node is obtained by security application and combined calculation, and the identity of an IPv6 network node is effectively hidden.

Description

technical field [0001] The invention relates to the field of IPv6 network technology, in particular to a method for protecting the identity security of IPv6 network nodes. Background technique [0002] With the implementation of the IPv6 development plan and the rapid expansion of the mobile Internet and the Internet of Things, the network environment is undergoing earth-shaking changes. At present, many countries have begun to set up IPv6 root servers, and IPv6 dual-stack transformation and IPv6 wireless networks have been gradually implemented. The mainstream Internet applications already support IPv6 access, user access traffic is increasing rapidly, and the number of new types of node devices connected to the network is growing explosively. More and more information in the real world will be transmitted in the virtual network, but the IPv6 protocol The IP address in the network is fixed and public, and the personal behavior and private information of user nodes are comp...

AI Technical Summary

Problems solved by technology

[0006] It can be seen that the identity security of IPv6 network nodes has not been effectively resolved, and the privacy of next-generation network nodes and users is facing severe challenges.
