Abstract
Recently, various cryptanalysis methods related to Cube Attack have attracted a lot of interest. We designed a practical platform to perform such cryptanalysis attacks. We also developed a web-based application at \url{http://cube-attack.appspot.com/}, which is open to public for simple testing and verification. In this paper, we focus on linearity testing and try to verify the data provided in several papers. Some interesting results produced in our work indicate certain improper assumptions were made in these papers
