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.

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...

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).
