Abstract

 

Recently, wireless communication has been popularly used in our everyday life. However, its security

is a crucial work since messages are broadcasted via wireless channels through which hackers

can intercept the massages and then know the contents of the messages. That is why security has

been one of the most important issues in wireless communication studies. Encrypting messages to

ciphertext is one of the methods to solve this problem. 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 ciphertext. In this paper, we proposed an authentication approach,

called the secure point-to-point encryption method (SePem for short), which integrates RSA,

Diffie-Hellman PKDS and a stream cipher technique to provide users with a highly secure point-to-point

wireless network without requiring a CA. According to the security analysis of this study,

the SePem can efficiently and securely protect a wireless environment. Our simulation results show that

the performance of this method can meet users¡¯ communication needs.
