The China Education and Research Computer Network Federated Authentication and Resource Sharing Infrastructure (CARSI) provides federal authentication and global academic information resource sharing services for universities and research institutions that have established unified identity authentication on campus networks. No VPN is required, and is not restricted by the authorization of the campus IP address. You can directly access authorized resources using a campus network account anywhere with the internet. Since the COVID-19 broke out in the spring of 2020, CARSI has effectively solved the pain point problem of academic resource access when teachers and students are at home, and gradually made a transition to comprehensively assisting the construction of campus informatization. The online resources cover various fields such as online teaching, industry data, scientific research support, intellectual property, news and information, innovation and entrepreneurship, tool software, and campus public services.Welcome more campus information resources to join CARSI.

CARSI services were initiated by Peking University Computing Center in 2006 and managed by China Education and Research Computer Network CERNET Network Center. Peking University Computing Center developed and provided technical support, while CERNET Corp. provided daily operations and user services. Based on the Shibboleth middleware technology led by Internet2, that supports the SAML protocol. This middleware is widely adopted by multiple national research and education networks NREN (National Research and Education Network) internationally. On May 24, 2019, CARSI Services officially became a full member of the international identity alliance organization eduGAIN. As of November 2024, eduGAIN has 5763 institutional (IdP) users, 3798 resource providers (SP), and 78 countries and regions as fully qualified member units. CARSI's joining eduGAIN not only makes it more standardized and convenient for Chinese universities to access global educational research resources, but also provides a basic platform for domestic resource providers that provide services to the education industry to go global.

As of November 2024, 811 universities and research institutes have joined CARSI, of which 679 have officially launched and 132 are currently undergoing testing, with over 10 million users. It is the second largest national and regional identity authentication alliance in eduGAIN, second only to the United Kingdom. We have gathered 278 products from nearly 130 resource providers, including Web of Science, Science Direct, ACS (American Chemical Society), CNKI, Wanfang, etc. We have access to over 440000 academic journals, 580000 multimedia resources such as videos and audiobooks, over 5.5 million e-books and textbooks, over 28.5 million dissertations, including over 2.1 billion patents and over 15.9 billion pieces of data, as well as basic information services such as digital certificates, municipal public transportation cards, Tencent Meeting, PDF editors, and operator 5G private networks.

CARSI will continue to play a role as a bridge and link, and we welcome more education resources to join.
