Blockchain-based ARP defense scheme

Abstract

In order to improve the difficulty of maintaining the static binding method when defending against ARP attacks,a defense method was designed with the features of low cost of defense and easy maintenance by using the idea of a blockchain technology.The blockchain structure had been improved,and the transaction index table structure had been designed to identify attacks and update data in a timely manner to prevent subsequent attacks.The content of the transaction index table was updated after the IP address was changed normally to ensure the correctness of the query.Analysis and experiments show that the blockchain-based defense method has the following merits:high security,guaranteeing the data is not tampered with,low cost of maintenance,and effective prevention against ARP spoofing attacks.
