There are many researches and technical proposals on cryptographic like from fundamental authentication to e-chsh and e-voting to solve wide-range of real-life security problems. On the other hand such proposal are not widely deployed in our society. This paper investigates the status, design of cryptographic protocols and implementation in Estonia (note in 2011), where PKI and e-voting are widely used, then discuss how cryptographic protocol like e-voting can be deployed in Japan.
