Wifi Certificate Android Here

| Field | Expectation | |-------|--------------| | | Select TLS, TTLS, or PEAP | | CA certificate | Dropdown of Wi-Fi installed CAs (not system CAs unless "Validate server" is on) | | User certificate | Dropdown of Wi-Fi installed client certs | | Domain (critical) | The SAN/CN of the RADIUS server (e.g., radius.example.com ). If mismatched, Android rejects even with valid CA. | | Identity (optional) | For EAP-TLS, often the certificate's SAN/CN or a string sent in EAP-Response/Identity. Can be left blank but may be required by RADIUS. | | Anonymous identity (outer identity) | Only for TTLS/PEAP. For TLS, irrelevant. |

1. Introduction: The Shift from PSK to PKI For years, Wi-Fi security meant Pre-Shared Keys (PSK) – a single password shared among all users. However, PSK is fundamentally broken for enterprise environments: it offers no user uniqueness, no revocation ability, and is vulnerable to offline dictionary attacks.
