Certificate Authority Vendors
In the Wi-Fi CERTIFIED Passpoint® certification program, mobile devices use Online Sign-Up (OSU) to accomplish registration and credential provisioning to obtain secure network access. Each Service Provider network has an OSU Server, an AAA Server, and access to a certificate authority (CA). A CA is a collection of computer hardware, software, and the people who operate it. The CA is known by two attributes: its name and its public key. One of the requirements for a mobile device and the hotspot to trust each other is that the OSU Server shall hold a certificate signed by a Certificate Authority whose root certificate is issued by one of the CAs authorized by Wi-Fi Alliance, and that these trusted root CA certificates are installed on the mobile device. A CA performs four basic CA functions:
- Issues certificates (i.e., creates and signs them)
- Maintains certificate status information and issues Certificate Revocation Lists (CRLs)
- Publishes its current (unexpired) certificates and CRLs so users can obtain the information they need to implement security services
- Maintains archives of status information about the expired or revoked certificates it issued
Certificates are governed by the Hotspot 2.0 Online Sign-Up Certificate Policy Specification. An OSU server certificate should be obtained from any of the CAs authorized by Wi-Fi Alliance as listed below.
