Though, thanks to NPKI(National Public Key Infrastructure), the Korean secure Internet transaction environment has been rapidly grown in the last decade, it also faces with several problems, which need to be solved in near future, mainly resulted from the lack of openness and compatability of the NPKI-based environment which is operating in a closed way. It is believed that those problems of the NPKI can be solved when it is implemented to be based on the SSL/TLS, an international standard for web-based secure Internet transactions. The transition to the SSL/TLS-based NPKI needs to be performed so that the advantages of current NPKI are well maintained. The purpose of this paper is to comparatively analyze the NPKI and the SSL/TLS so as to give basic idea of implementing the current NPKI to be based on the SSL/TLS. The analysis will show not only how the SSL/TLS-based NPKI can improve current NPKI but also how the advantages of current NPKI can be maintained by the SSL/TLS-based NPKI.
