Current Status of Japanese Government PKI Systems

  • Conference paper

Part of the book series: Lecture Notes in Computer Science ((LNSC,volume 5057))

Abstract

In Japan, three government PKI systems are constructed as Bridge Model PKI, and they are also bridged with each other. Up to now, all of the three PKI systems have issued certificates mainly for digital signature on digital documents. Only recently, a concern to issue certificates for entity authentication has been raised. Not only “KeyUsage” but also “CertificatePolicies” and related extensions should be carefully used in Bridge Model. As a potential international issue, we have started to discuss on the migration of cryptography in PKI systems. Due to Bridge Model and vertically divided administration, difficulties in enforcing consistent policies thoroughly in these PKI systems is expected in Japan.
