OTP Encryption Enhancement Based on Logical Operations

Abstract

With continuous development of hacking technologies, it is necessary to provide users with a protected background that secures their resources against unlawful access by enforcing control mechanisms. To neutralize such these threats, the enhanced one time pad (OTP) technique has been introduced. Accordingly, to encrypt text, the key is combined with the message. The key length has to have a same length of the message. In this paper, a new method to enhance OTP data encryption using AND and XOR functions has been adopted. Firstly, message and original key are combined by logical AND operation, then the new text will be XORed with a key again to produce more complicated cipher.
