Research And Application Of SSL Protocol On ZigBee Data Acquisition And Transmission System

The data acquisition and transmission is a necessary part for a industrial control system. With the development of science and technology, wireless sensor networks are used in some particular industrial environment .And synchronously people want to build a secure syetem to make their data private. In recent years, security in data acquisition and transmission is a hot research spot.This paper builds a framework of the secure data acquisition and transmission system with SSL protocol and OpenSSL software package, accodrding to current network security technology and developed wireless sensor networks project .In this paper, security data transmission tunnel including key technology ,WSN technology and function module is the key point. Data privacy, data integrity and reliable connection are provided in this system.Security data transmission tunnel with C/S structure provides security data transmission and data can be encrypted when acquired.For a actual control system, data security is important and necessary.This paper focuses on it.However, the system is not perfect because of other problem in application. To improve it, there is muchwork to do and that will be the new research directions.
