Certified Information Privacy Technologist (CIPT) — Question 146

During a transport layer security (TLS) session, what happens immediately after the web browser creates a random PreMasterSecret?

Answer options

• A. The server decrypts the PremasterSecret.
• B. The web browser opens a TLS connection to the PremasterSecret.
• C. The web browser encrypts the PremasterSecret with the server's public key.
• D. The server and client use the same algorithm to convert the PremasterSecret into an encryption key.

Correct answer: C

Explanation

The correct answer is C because the web browser needs to encrypt the PreMasterSecret with the server's public key to ensure that only the server can decrypt it. Option A is incorrect as the server cannot decrypt the PreMasterSecret until it is encrypted by the browser. Options B and D are irrelevant to the immediate action taken after generating the PreMasterSecret.
