Which of the following statements best explains how encryption works on the Internet?

The correct answer is A. Encryption encodes information using specific algorithms with a string of numbers known as a key.. Encryption is the process of transforming readable data (plaintext) into an unreadable format (ciphertext) using a mathematical algorithm and a cryptographic key - a string of numbers or characters. Only parties with the correct key can decrypt and read the original information.

Explanation

Encryption is the process of transforming readable data (plaintext) into an unreadable format (ciphertext) using a mathematical algorithm and a cryptographic key - a string of numbers or characters. Only parties with the correct key can decrypt and read the original information. Options B, C, and D describe authentication, access control, and transaction processing respectively, none of which accurately describe the core mechanism of encryption itself.
