Hi there. Please help me here!

1.Determine the truth value in the statement that Rabin cryptosystem is a variant of the Elgamal Cryptosystem.

2.Given that the ciphertext is (28,9), determine the plaintext to be transmitted. 45 is the random integer, p equals 107, e1 equals 2, d equals 67 according to the sender.

3.Calculate for the value of e2 in an Elgamal cryptosystem given that 31 represents the prime, d equals 10 and e1 represents the first primitive root of p.

4.Given the prime p equals 31 in an Elgamal cryptosystem, use 00- 25 for encoding and encrypt 'HELLO' as the message. Character 'O' will be represented by which character of C2.

5.Given the prime p equals 31 in an Elgamal cryptosystem, use 00- 25 for encoding and encrypt 'HELLO' as the message. Character 'L' will be represented by which character of C2.

6.Given the prime p equals 31, determine the plaintext character for C equals (27, 20) in Elgamal cryptosystem.

7.Determine the subset that sums to V which equals 302 given that you only have a set of weights {62, 93, 26, 52, 166, 48, 91, & 141}.

8.Describe the Cryptographic system that uses C1 = (e2^rx P) mod p and C1 = (e1^r) mod p at the side of the encryption.

9.Determine the cipher text for the value of the plaintext 10011 given the Knapsack {1 6 8 15 24}.

10.Determine the Cipher text given the Rabin cryptosystem where p equals 23 and q equals 7. Also, p is encrypted to 24 so as to find the ciphertext.
