The CILogon Certification Authorities provide certificates to users of the United States National Science Foundation cyberinfrastructure. The CAs provide the foundation for the CILogon Service. Identity providers in the InCommon Federation identify and authenticate certificate applicants. The CILogon Silver CA is based on the InCommon Silver Identity Assurance Profile. It has been accredited by The Americas Grid Policy Management Authority (TAGPMA), our regional member of the International Grid Trust Federation (IGTF). The CILogon Basic CA provides certificates to InCommon members that do not currently meet the InCommon Silver Profile. The CILogon OpenID CA provides certificates based on OpenID authentication.

Subscribers access the CAs at https://cilogon.org.

Links to CA certificates, CRLs, etc., are provided on the Downloads page.

  • CILogon OpenID CP/CPS V3
    We have updated Section 3.1 (Naming) of the CILogon OpenID CA Certificate Policy and Practice Statement (CP/CPS). Now certificate subjects include the subject's name, as provided by the OpenID Provider, rather than the OpenID Identifier URL. Also, the CILogon OpenID CA will now include email addresses in certificate subject alternative names.

  • CILogon Silver CA Accredited by IGTF
    Today's announcement of the IGTF 1.38 distribution marks the final step in the accreditation of the CILogon Silver CA by the International Grid Trust Federation (IGTF). This follows the approval in October of the CILogon Silver CA Policy by The Americas Grid Policy Management Authority (TAGPMA). The CILogon Silver CA relies on campus authentication that satisfies the InCommon Silver Identity Assurance Profile, so it will not be fully operational until the first InCommon campuses are accredited at the Silver level under the InCommon Identity Assurance program. To serve researchers from campuses that are not (yet) at the InCommon Silver level, CILogon also operates Basic and OpenID CAs at https://cilogon.org.
