What is the purpose of Public Key Infrastructure (PKI)?

• A. To manage server load and network traffic
• B. To manage digital certificates for secure communication
• C. To protect physical access to data centers
• D. To store sensitive information in a database

Answer: (B)

The purpose of Public Key Infrastructure (PKI) is to manage digital certificates for secure communication. PKI provides the necessary framework to create, manage, store, and revoke these certificates, which are essential for establishing the authenticity and integrity of communications over untrusted networks, such as the internet. By utilizing asymmetric cryptography, PKI enables secure data exchange, allowing users to verify each other’s identities through public and private key pairs. The digital certificates issued by PKI assure users that their communications are protected from impersonation and eavesdropping, thereby significantly enhancing security protocols like SSL/TLS used in web transactions and email communications. In this context, the other choices do not relate to the primary functions of PKI. Managing server load and network traffic relates to network management rather than certificate management. Protecting physical access to data centers focuses on physical security measures instead of digital identities and communications. Storing sensitive information in a database pertains to data storage and management practices, which are separate from the functions provided by PKI.
