In this paper, the authors present a different way for implementation of one-time pad. The one-time pad are known as the mother of all encryption schemes, since it is known to be information-theoretically secure in contrast to other encryption schemes used in practice, which are at most computationally secure. Their proposed way will make encryption impossible to crack if used correctly. They are implementing one-time pad encryption technique using both block cipher and one-way hash. In this proposed method each bit or character from the plaintext is encrypted by a modular addition with a bit or character from a secret random key of the same length as the plaintext, resulting in a cipher text.
