Status Survey of SSL/TLS Sites in 2018 After Pointing Out About "Search form" Issues

Abstract

We report status survey of SSL/TLS sites in 2018 after pointing out about "search form" issues. From 2014, several researchers were conducting fixed point observation to crawl SSL/TLS sites using. jp domain URL list extracted from Alexa Top Sites, and investigation on improvement of usage rate of SSL/TLS versions and Export-grade encryption algorithms. They also pointed out that on-line login sites belonging to the an association of Japanese banks were well-controlled in SSL/TLS server configurations and also contents management, however ordinary sites had "search form" issues. In this paper, we re-investigate the status of SSL/TLS sites including Japanese banks.
