Lately, the security in wireless network is always a really hot topic. With the popularity of wireless network in our daily life day after day, the issues of connection speed have evolved to emphasize on personal privacy and information security.
Due to the complication of membership in wireless network, it is hard to identify every member. We can reference to the security mechanism in wired network, and try to modify it to fit in wireless network. Of course, the wireless devices do not have such strong processing power and resources as personal computers or servers. So when we try to modify the security mechanism in wired network, we should think about the difference between wired and wireless devices.
In this paper, we use a special method to establish Ad Hoc network architecture, and SSL ( Security Sockets Layer ) security protocol. Because SSL has been widely implemented and is now the main standard for providing security e-commerce transactions over the Web. Besides, we use ECC ( Elliptic Curve Cryptosystems ) to replace traditional RSA. Though RSA is the most widely used public key cryptosystem today, the implementation of RSA requires expensive computation. Since battery/computing power and bandwidth are scarce in mobile and wireless systems, the use of a computationally intensive cryptosystem, such as RSA, is not a feasible choice in such environments. Then we can establish a security environment in Ad Hoc network.
We hope we can take a excellent balance between security and processing complexity. This paper goes toward the direction, and tries to move SSL to wireless networks. We believe that it is a method to give consideration to practical utility and ideal.
