What does PKI mean?

1. Password/Key Identification

2. Passive Key Identification

3. Public Key Infrastructure

4. Private Key Infrastructure

The correct answer is: Public Key Infrastructure

PKI stands for Public Key Infrastructure, which is a framework that enables secure communication over networks by using cryptography. It involves the management of digital certificates and public-private key pairs. PKI allows users to send secure data, authenticate identities, and ensure the integrity and confidentiality of communications. The core functions of PKI include the issuance, management, and revocation of digital certificates, which bind public keys to the identities of individuals or organizations. This system relies on trusted Certificate Authorities (CAs) that validate identities and issue certificates, thereby establishing a chain of trust. Understanding PKI is crucial for cybersecurity professionals as it underpins many technologies and protocols used for secure transactions, including SSL/TLS for secure web browsing and email encryption.
