Abstract(in Japanese) (See Japanese page)
Abstract(in English) Frameworks like SAML or Shibboleth have been developed so that various internet services can be used more sucurely and seamlessly. In these frameworks, however, a user must exchange one's attributes by immidiate value between one's identity provider and sevice providers. Without any extensions, they cannot directly communicate conditions about users' attributes that should be satisfied to authorize them. Consequently, there are cases where users must present detailed information that service providers don't actually require. In this paper, we discuss the issue. We focus on Shibboleth and propose an extension of the attribute exchange protocol of Shibboleth, that will solve the issue.
