Research And Implementation Of Secure Access Platform Of Data Collection Terminal Based On Commercial Password

With the development of smart grid, data collection terminals,eg wireless meter reading, automatic voltage acquisition, have been widely used. Secure and reliable transmission of data becomes an urgent problem. There are two problems secure access platform traditional data acquisition terminal. One is that data communication uses the RSA encryption algorithm, the other is both sides in the communication use VPN technology to establish a virtual connection. First, RSA key system can not satisfy the security requirements with the enhancement of computing power. Second, using VPN technology will need to install a client. PC, android phone, iphone can meet this, but data collection terminal can not, it is Embedded Systems. Apart form this, the large number of data collection terminals take high concurrency. Then, Secure Access Platform will be under great pressure, and must use efficient 10 model.The main work of this article is the design and implementation of the voltage acquisition system. The system is a Secure Access Platform based on data collection terminal and uses SM2, SM3 algorithm. The objectives of our study are to:(1)Introduce the SM2 algorithm and implementation. National Bureau announced SM2 algorithm,but not show the source code. We need to implement the algorithm.(2)Research SM3 hash algorithm. Proposed secure communication protocol between Security Access Platform and data collection terminal.The protocol is based on SM2 and SM3. Data collection terminal can communicate with Security Access Plateform in this protocol.(3)Rearch IOCP and epoll. Rearch IOCP in Windows and epoll in Linux for high concurrency, and summarize the advantages and disadvantages of each model(4) Introduce and implement voltage acquisition system. Design and implement Secure Access Platform of collection voltage terminals in windows system. Achieve secure and reliable voltage data transmission...
