If Alice sends Bob an encrypted message using RSA, which consequence directly follows from the properties of modular exponentiation?

A)The message is vulnerable to frequency analysis.
B)Bob can decrypt it with Alice's private key.
C)The ciphertext's length decreases after encryption.
D)Bob can decrypt it with his private key.

💡 Explanation

With RSA, Bob can decrypt the message using his private key because the decryption process relies on modular exponentiation, which is the inverse of the encryption operation. Therefore, Bob needs his private key, rather than Alice's or frequency analysis, to reverse the encryption process.
