IPv6 network node data security transmission method

Abstract

The invention discloses an IPv6 network node data security transmission method. The IPv6 network node data security transmission method comprises the following steps of: a network node A sends an encrypted communication request packet to a network node B according to a routing path order; the network node B performs key sharing on key data K with the network node A through a key relay path consistent with the routing path; the network node A performs combinatorial computing on the key data K, the IP address of the network node A, and the IP address of the network node B to obtain a new key K<AB>; and the network node A encrypts the data to be sent by using the new key K<AB>. The IPv6 network node data security transmission method uses the BB84 protocol to perform quantum key distribution,and the key generated by a quantum key distribution terminal is transmitted to a router, which is more secure than a traditional cryptosystem; moreover, the new key K<AB> is calculated through a combined operation mode, therefore, the key utilization and encryption security are improved; and the data security problem of the IPv6 network node can be effectively solved, and the economic loss of thesociety and an individual caused by leakage of network data is reduced.

Problems solved by technology

[0005] At present, most of the network nodes are not encrypted, and even if they are encrypted, most of them encrypt IP layer data based on the IPSec protocol. The key negotiation of the IPSec protocol adopts the D-H protocol, which is a key negotiation system based on computational complexity and requires relatively high computing power. High hardware support, it is difficult to apply in the field of embedded physical network, and with the development of computer computing power, the D-H key agreement system is gradually no longer safe

[0006] In the IPv6 network, the problem of data security is further amplified. The next-generation network nodes are no longer complete computer systems. Some nodes may only have a single function of capturing environmental parameters and network transmission. The data of such nodes is extremely important. , the data sent often carry a lot of real-world information (such as images, sounds, locations, status, power consumption, etc.), if stolen and decrypted by malicious eavesdroppers, and then use big data analysis methods to analyze the data, you can get the All the information of network nodes will constitute a great security risk in the future world, and the consequences will be disastrous
