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.
