Episode 13 — PKI Foundations: Public Keys, Private Keys, and Trust (1.3)
This episode introduces public key infrastructure as a trust system that supports encryption, authentication, digital signatures, and secure communication. Public keys can be shared, while private keys must be protected because they prove identity, decrypt protected information, or create signatures. The exam expects students to understand that PKI depends on key pairs, certificates, certificate authorities, trust chains, and strong private key protection. In real environments, private key exposure can allow impersonation, decryption, or fraudulent signing, so key storage, access control, rotation, and revocation all become important security considerations.
