Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If the received cipher text is C = 49, what is the corresponding plaintext (suppose (n, d) = (55, 3) is the private key of an RSA cryptosystem)?
A
4
B
5
C
3
D
6
E
2
Explanation: 

Detailed explanation-1: -Question 22 1 pts Suppose (n, d) = (55, 3) is the private key of an RSA cryptosystem: If the received ciphertext is C = 49 what is the corresponding plaintext? 3 4 10 14. So, the public key is $(n, e) = (55, 27)$.

Detailed explanation-2: -The correct answer is transposition ciphers.

Detailed explanation-3: -Asymmetric key algorithms or ciphers use a distinct key for encryption and decryption.
