Certified in Risk and Information Systems Control (CRISC) Practice Test

The Caesar Cipher technique is associated with shifting the characters of the alphabet. This classic encryption method involves replacing each letter in the plaintext with a letter found by moving a fixed number of places down or up the alphabet. For example, with a shift of three, 'A' would become 'D', 'B' would become 'E', and so on. This approach is straightforward and demonstrates the fundamental principles of substitution ciphers, making it an essential concept in the study of cryptography.

In contrast, the other options describe different aspects of cryptographic techniques. Using large prime numbers pertains to more advanced encryption methods like RSA, which are based on number theory rather than character shifting. The mention of symmetrical keys relates to encryption techniques that utilize the same key for both encryption and decryption, which is not specifically characteristic of the Caesar Cipher. Lastly, transforming text to binary refers to the digital representation of text, which is distinct from the substitution cipher mechanism employed in the Caesar method.
