Proposal of new authentication method in Wi-Fi access using Bitcoin 2.0

Abstract

Recently, Wi-Fi hotspots are installed at several places. However most communications are not encrypted and the illegal can use it maliciously, therefore effective breakthrough are required. We propose a solution of these problems using a new method derived from Bitcoin. This method uses Blockchain and logs of user access are saved to it. The administrators can identify illegal person and collect user's statistics. Bitcoin address can be used as encryption keys for communications. The Blockchain also provides a platform of regional applications. Furthermore, systems can cooperate with others at different places.
