Let p=11, q=17, n = pq = 187. Your (awful) public RSA encryption
key is (e=107, n=187). (a) What is your private decryption key? (b)
You receive the encrypted message: 100 Decrypt the message. (In
other words, what was the original message, before it was
encrypted? Just give me a number, don’t convert it to letters).

For solving the problems, you are required to use the following
formalization of the RSA public-key cryptosystem.
In the RSA public-key cryptosystem,
each participants creates his public key and secret key according
to the following steps:
· Select two very large
prime number p and q. The number of bits needed to represent p and
q might be 1024.
· Compute
n = pq
(n) = (p – 1) (q – 1).
The formula for (n) is owing to...

Suppose the totient for a given public key (52,494,503;7) is
inadvertently released and is equal to 52,479,768. What are p and
q? What is the decryption exponent d? For extra credit what is the
plaintext message of the ciphertext C=15,114,578 encrypted with the
given public key?
Alice uses RSA to send a key to Bob for use in encryption of

Alice uses RSA to send a key to Bob for use in encryption of
future messages. The key is the word ”CINEMA” and the encoding from
letters to numbers is done using the ASCII: A = 65 ... Z = 90,
space = 99. The public parameters (n, e) = (9379, 11) are shared.
Encrypt Alice’s key word, using 2-letter blocks. Please show
work.

Let p = (8, 10, 3, 11, 4, 0, 5, 1, 6, 2, 7, 9) and let q = (2,
4, 9, 5, 10, 6, 11, 7, 0, 8, 1, 3) be tone rows. Verify that p =
Tk(R(I(q))) for some k, and find this value of k.
