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.
