For p = 11 and q = 19 and choose d=17. Apply RSA algorithm where Cipher message=80 and thus find the plain text.(a) 54(b) 43(c) 5(d) 24This question was addressed to me in an interview.This interesting question is from Knapsack/ Merkle in chapter Public Key Cryptography and RSA of Cryptograph & Network Security

Answer» RIGHT option is (C) 5

Explanation: N = pq = 11 × 19 = 209.

C=M^e mod n ;C=5^17 mod 209 ; C = 80 mod 209.
