CRYPTOGRAPHY
In One Time Pad (OTP) encryption, you could XOR the plaintext bits with the ciphertext bits to derive the key. However, the derived key is of no use as it is not used for encryption anymore in OTP. Now, consider a flawed OTP -like cipher: Assume an OTP -like encryption with a short key of 128 bits. This key is then used periodically to encrypt large volumes of data. Describe how an attack works that breaks this scheme?
