Explanation
X.509 is the standard format for digital certificates used in Public Key Infrastructure (PKI). PKI uses these certificates to authenticate users and devices by binding a public key to an identity through a Certificate Authority (CA). Kerberos uses tickets and symmetric key cryptography, not X.509 certificates. TACACS+ and RADIUS are AAA protocols that support various authentication methods but are not inherently certificate-based systems - PKI is specifically the framework that issues and manages X.509 certificates for authentication.
