6. The following questions are based on RSA Algorithm. a) Describe the format of the public and private keys of the RSA Algorithm (2 marks) b) List the value of the Euler function o(n) for n that is the product of two primes p and q? (2 marks) C) Is it safe to reveal the value of pin) corresponding to the public modulus of an RSA encryption scheme? Justify. (4 marks) d) If M is a message, and E = Encode(M) is a secure encoding of M as an integer in {0,....n-1), state the value of the public key encryption of M using RSA public key (ne) (3 marks) (CLO2UPLO2:C2)
