Is there Information on Payment Gateway Protocol in Korea e-commerce?

There's many ActiveX programs in Banking and E-Commerce in Korea. So, Almost program runs on IE and MS Windows.

There's some reason, in Korea They use their own spec of Certification and Own Encryption algorithm , named "SEED"

and other closed protocol as I know,

I want to implement that with No additional activeX or Plugin . wholey use Java or JavaScript in Browser side .

Please answer Any Information for implement it.

Thanks in advance.
