[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

Embodiment Construction
[0016] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.
[0017] In order to solve the technical problem that after the IPv6 address mentioned in the above-mentioned background technology is known, it is easy to cause other devices to access the corresponding products based on the IPv6 address, resulting in related products being disturbed by malicious access, the present invention provides a blockchain-based network Authenticated screening of visits to filter out visits that might interfere with related products.
[0018] Among them, for the clarity of description, the access attack pr...

The invention discloses an access attack protection method and system based on a blockchain domain name system, wherein the method includes: after the visited communication node receives the IP access connection request sent by the visiting communication node, querying the visited communication node in advance Set the communication security level. If it is known that authorization verification is required for the visiting communication node, the IP access connection request is parsed to obtain the visiting IPv6 address of the visiting communication node, and the locally stored blockchain account book is obtained and accessed according to the visiting IPv6 address. The user information of the visiting communication node corresponding to the IPv6 address, the visited communication node authenticates the visiting node according to the user information, and if the authentication passes, it is allowed to visit the corresponding visited node. Therefore, based on the blockchain network, the access verification of communication nodes is realized, and only nodes that pass the verification can access it, avoiding malicious interruption of communication nodes.
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...
