Security has been one of the most important issues in wireless communication. Encryption of messages into cipher text is one of the techniques to provide security up to some extent but, it also causes another problem, i.e., how to safely and confidentially encrypt and deliver security keys so that hackers have to spend a very long time before they can decrypt the cipher text. In this paper, the authors' main aim is to devise a secure point-to-point encryption method for a wireless communication environment. Novel Diffie-Hellman-based Public Key Distribution System has been implemented, which adopts a stream cipher technique to encode plaintext with a pseudo random number sequence.
