[0003] However, with the popularization of the network, the publicity of IPv6 addresses is also strong. Any device that knows the IPv6 address of a product can access the corresponding product, which increases the probability of malicious access to many products. How to Avoiding malicious access and effectively regulating the access environment has become a requirement

The invention discloses an access attack protection method and system based on a block chain domain name system. The method comprises the following steps of: enabling the accessed party communicationnode to receive an IP access connection request sent by the access party communication node; inquiring a communication security level preset by the communication node of the accessed party; if it is known that authorization verification needs to be carried out on the access party communication node, analyzing the IP access connection request to obtain an access IPv6 address of the communication node of the access party; and inquiring a locally stored blockchain account book according to the IPv6 access address to obtain user information of an access party communication node corresponding to the IPv6 access address, carrying out identity authentication on the access node by the accessed party communication node according to the user information, and if the authentication is passed, allowingthe accessed party communication node to access the corresponding accessed node. Therefore, the access verification of the communication node is realized based on the block chain network, and the communication node is accessed only by the verified node, so that the communication node is prevented from being disturbed maliciously.
Description
technical field [0001] The present invention relates to the technical field of computer communication, in particular to an access attack protection method and system based on a blockchain domain name system. Background technique [0002] With the development of computer technology, more and more attention has been paid to the security of the computer network environment. Among them, as IPv6 addresses are gradually becoming popular, computer devices generally use IPv6 addresses as their own device addresses. [0003] However, with the popularization of the network, the publicity of IPv6 addresses is also strong. Any device that knows the IPv6 address of a product can access the corresponding product, which increases the probability of malicious access to many products. How to To avoid malicious access, it is necessary to effectively regulate the access environment. Contents of the invention [0004] The present invention provides an access attack protection method and syst...
