The security analysis of e-voting in Japan

Abstract

To assess trustworthiness of e-voting practices in Japan, security of e-voting systems and their operational procedures are analyzed. All e-voting systems available on the market are covered in the analysis. Through the analysis we concluded that current e-voting security is heavily depending on protection by operational process rather than security features of the system and it is confirmed that the systems provide only limited security features and there is large room for technical improvement. Typical security issues are lack of protection mechanism of programs and data on tabulation machines. This vulnerability enables malicious poll worker or manufacturer to insert malicious code to generate arbitrary election results. © Springer-Verlag Berlin Heidelberg 2007.
