A one-round symmetric-key block cipher Plaintext-ciphertext pairs Goal is to find the key Use the pairs to check whether your answer is correct

All Subkeys are chosen randomly (except Subkey3 and Subkey7) Subkey 3 and 7 are generated from Subkey 2 and 6 by performing bit-wise right shift by 2-bit, respectively

Subkeys 2--------------------------->Subkey 3 (16bits) 2bit right shift (16bits)

Subkeys 6--------------------------->Subkey 7 (16bits) 2bit right shift (16bits)

You are given four plaintext-ciphertext pairs

(0x6018 E590 FDA5 84A9, 0x3AC5 37CD 9CD1 724E)

(0x0A81 ECF1 281E DA5A, 0x192C 94BE C3CA 69ED)

(0x2E70 91D3 0AF3 45A0, 0x 0B2D A334 CD6F D8F7)

(0xF778 A320 1457 4AB1, 0x7BA5 5825 5367 2DF6)

Question: To find the eight Subkeys (solve it by Java or C programming,and show it)

PS: Comment to your source code Explain what functions, variables, etc., you use in your source code do Screen capture of the running program Explain what the captured images mean Answer List the values of eight Subkeys 3. Executable file: Project_1.exe, etc.
