RSA public key cryptosystem, the private and public keys
In the RSA public key cryptosystem, the private and public keys are (e, n) and (d, n) respectively, where n = p*q and p and q are large primes. Besides, n is public and p and q are private. Let M be an integer such that 0 < M < n and f(n) = (p 1)(q1). Now consider the following equations. I. M’= Me mod n M = (M’)d mod n II. ed ≡ 1 mod n III. ed ≡ 1 mod f(n) IV. M’= Me mod f(n) M = (M’)d mod f(n) Which of the above equations correctly represent RSA cryptosystem? A I and II B I and III C II and IV D III and IV
