Based on the Research of WSN in Information Security Technology

With the advance of technology, people is more and more nervous to security threats posed by wireless sensor. Therefore, Based on security technology, this paper puts forward a suitable for the safety management unit used in wireless sensor network, And the provisions of its agreement, authentication methods and security processing methods, making wireless sensor networks can transmit user information in a secure environment, while simulation analysis the affect design module on date security transmission, when the wireless sensor networks have security management unit, it will a better, more reliable transmission environments.
