| Abstract(in English) | The issue of cryptocurrency exchanges gains prominent attention by the incidents that a large amount of NEM is leaked from CoinCheck, Inc, some currencies are leaked from Tech-Bureau, Inc. There are hundreds of exchanges in Japan and overseas as long as we know, and these are some suspicious exchanges. Thus, it is important to understand the actual conditions of exchanges from a viewpoint of user protection. We investigated and analyzed the security of exchange's Web server about TLS Certificates, Wallets at ISEC workshop in May 2018, and revealed undesirable exchanges for security. In this paper, we conducted a survey with increased target cryptocurrency and analysis content, and compare once with twice, and report the result. |
