In this paper, the authors show how implemented one time security encryption scheme is more lucid, effective. However it is more complex in nature of attacker view. The one-time pad encryption scheme itself is mathematically unbreakable. (See Claude Shannon's \"Communication Theory of Secrecy Systems\"). Therefore, the attacker will focus on breaking the key instead of the cipher text. Random key stream can be used to create lifetime supply of keys for one time pads. Here, they provided the practical approach that the people can use to set up their own one-time pad encryption. Permutation techniques can be used in conjunction with other technique includes substitution, encryption function etc. for effective performance.
