","subitem_description_language":"ja","subitem_description_type":"Abstract"},{"subitem_description":"In this paper, we discuss an institutional unified authentication and authorization infrastructure using Central Authentication Service (CAS) developed by Yale University and its extension to Central Authentication and Authorization Service (CAS^2). Since CAS server only treats authentication information, hence CAS provides a Single Sign On service in a more secure manner. Moreover CAS is implemented on typical standard Web technologies so that the required implementation cost is quite low. We also discuss security problems of CAS, and we improve CAS as CAS^2. Furthermore, we explain the deployment of CASified Nagoya University Portal and a Web-based course registration application at 2005 first semester and summarize our experiences with the discussion of further extensions in CAS^2.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10_identifier_60":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2237/10271"}]},"item_10_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"情報処理学会","subitem_publisher_language":"ja"}]},"item_10_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"ここに掲載した著作物の利用に関する注意 本著作物の著作権は（社）情報処理学会に帰属します。本著作物は著作権者である情報処理学会の許可のもとに掲載するものです。ご利用に当たっては「著作権法」ならびに「情報処理学会倫理綱領」に従うことをお願いいたします。 Notice for the use of this material The copyright of this material is retained by the Information Processing Society of Japan (IPSJ).
