What are the two important components of a public key infrastructure (PKI) used in network security? (Choose two.)
- digital certificates
- pre-shared key generation
- symmetric encryption algorithms
- intrusion prevention system
- certificate authority
| Explanation & Hint:
A public key infrastructure uses digital certificates and certificate authorities to manage asymmetric key distribution. PKI certificates are public information. The PKI certificate authority (CA) is a trusted third-party that issues the certificate. The CA has its own certificate (self-signed certificate) that contains the public key of the CA. |
