A simple encryption method is being used to encrypt a small number (called the secret number). The method by which this encryption works is as follows: I. Choose a random seed number II. Calculate the key by multiplying the seed with the secret under modulus 7 II. Finally, multiply the key with the secret to get the encrypted secret Example: If our secret number was 45 Randomly choose seed = 6 key = secret x seed (mod 7) = 45 x 6 (mod 7) Encrypted Secret = key x secret = 45 x 4 = 180 %3D %3D Based on this encryption method, when choosing the random seed, show which number should not be used, because it would result in the Secret and the Encrypted Secret being the same.

1- A simple encryption method is being used to encrypt a small number (called the secret number). The method by which this encryption works is as follows: I. Choose a random seed number II. Calculate the key by multiplying the seed with the secret under modulus 7 III. Finally, multiply the key with the secret to get the encrypted secret Example: If our secret number was 45Randomly choose seed = 6 key = secret x seed (mod 7) = 45 x 6 (mod 7) = 4Encrypted Secret = key x secret = 45 x 4 = 180 Based on this encryption method, when randomly picking a seed number, show which number should not be picked, so that the Encrypted Secret we end up within the end is not the same as the original Secret Number we started with.
