Certified Encryption Specialist (ECES) v3 — Question 4

In order to understand RSA, you must understand the key generation algorithm as well as the encryption and decryption algorithms. Which one of the following equations describes the encryption process for RSA?

Answer options

• A. P = Cd mod n
• B. Ce mod n
• C. y2 = x3+Ax+B
• D. Me mod n

Correct answer: D

Explanation

The correct option, D, represents the encryption process in RSA, where M is the plaintext message, e is the public exponent, and n is the modulus. Options A and B do not reflect the correct encryption formula for RSA, and option C is a mathematical equation unrelated to RSA encryption.
