What is the difference between a hash function and a redundancy function? The redundancy function must have the same domain and range The redundancy function is also a one-way function but it doesn't require a key Despite the redundancy function, a hash function is a one-way function They are the same with different applications > Question 18 Assuming that the "Enc" function of RSA algorithm is as follows: C-Me (mod N) Where "C" is the cipher, "M" is the message and "e" is the public key, If the cipher is "855", the private key is "2753", and N is 3233, what would be the message M? M-2753 855 (mod 3233) M-855 * 3233 (mod 2753) M-8552753 mod 3233) M-2753A 3233 (mod 855)
