Based On The Ssl Protocol, Data Collection And Transmission System Applications

The data acquisition and transmission of family metering device is an importmant part of intelligent plot. With the development of science and technology , economical level and inhabitant living standard, people urgently need to develop the way of data acquisition and transmission and establish the intellectualized and secure data processing syetem.As a result of the computer and the network technology rapid development, the network security question propose the stern challenge to the people, and it has become the current research hot spot.This paper builds the framework of the secure data acquisition and transmission system with SSL protocol and opening source code OpenSSL software package, accodrding to current network security technology and developed intelligent heat meter project .In this paper, security data transmission tunnel including key technology ,data structure and function module is key point. Data privacy ,data integrity and reliable connection are provided in this system.It mainly includes two parts of data acquisition and data transmission. Two methods of serial port and TM card used to gather data are introduced. The later way integrates TM card key technology and simple DES algorithm to encrypt important data. In the data transmission part security data transmission tunnel with C/S structure provides security data transmission between two ends.In this paper .system mainly framework , main function modules and basic data structure are established. The data acquisition way using TM card with simple DES algorithm and security data transmission tunnel are separately established too. However, the system is still at experimental stage. To improve it, there are lots of work to do and those will be the later research work directions.
