Assume you are constructing an RSA algorithm with p = 3 and q = 5
a) Find the number of relatively prime (with n) positive integers less than n: p(n) =?
b) Choose a proper public key: e =?
c) Calculate the corresponding private key: d =?
d) Write the expressions for encryption and decryption functions if plaintext block is denoted by x and
ciphertext block is denoted by y.
e) Write the expression for your digital signature if the message to be signed is m.
If m = 02 what is the numeric value for
f)
a. encrypted(m)
b. digitally signed (encrypted (m))
