The Design And Research Of The Wireless Internet Access Terminal Based On The WAPI

With the development of network technology and the popularity of the Internet,Internet of Things has become a hot topic. The conception of Internet of Things haschanged people’s traditional means of access to information, the information networkinto a new phase. Exchange by information transmission terminal and thetransmission network will be a variety of physical objects, including securitymonitoring systems, intelligent tracking systems, corridor control system for a varietyof information management system of information between them made it to theintelligent management has taken a new step. Through all kinds of informationtransmission network to realize a efficient interconnected, through the cloud system torealize the resources sharing, to ensure the system in an stable operation，and by usinghighly strength of information security technology, provide an All-round securityservice for the system, and it covers various functions such as the real-timemonitoring, remote location, historical records, intelligent fault analysis and the limitalarm, processing feedback and so on, it completes a series of work to the contentwithin the network such as the object monitoring, managing, analysis, processing,keep the historical data.WAPI is a national standard that released in2003by our country. The wirelesslocal area network identification and confidential basis institutions, a new safetymechanism specified by the Broadband wireless IP standard working group, is animportant part of this standard. This is the only approved agreement at present in ourcountry in the WLAN field, it is for a new generation of security solutions that erectedby the IEEE802.11WEP Safety problems. WAPI uses public-key system of ellipticencryption algorithm and the private key system of block ciphers algorithm that arecommitted by the password administration committee office of the country, thealgorithms each are used in the digital certificate, WLAN equipment key agreementand transmission of the data encryption, by this way,we can achieve the equipmentidentification, linking identification, accessing control and customer information inthe wireless transmission state of the encryption protection.This paper based on project "the communication module based on WAPI".This paper designs a kind of information access terminal based on the concept of Internetof Things, information receiving and outputs. Article the following statement:1. This paper first introduces the research background, research purpose andmeaning.Wireless network with the flexibility of networking and high transfer rate,are discussed in detail including WLAN, Bluetooth technology, the purple peakstechnology mainstream technical background and characteristics, and elaborated themost important security of these wireless technologies problem, Finally the researchsituation at home and abroad.2. For wireless network security issues, the ISO has formulated the standard,China has also raised the safety standards of the WAPI with independent intellectualproperty rights. This detailed the WAPI standard certification system, theestablishment of the security association (including the infrastructure mode and adhoc network mode) and WAPI identification of infrastructure, Two-way authenticationprocess of the WAPI protocol is detailed. WAPI technology-based informationexchange mechanism, the introduction of WAPI Privacy Infrastructure, discussed thesafety performance of the communication process. This part focuses on the ECCalgorithm and ECDSA algorithm based on the WAPI technology.3. Introduces the design of the whole system, complete hardware diagram fromthe system hardware design, complete the ECC algorithms based on WAPI from thesystem software design. Algorithm is an important module of the WAPI; it mainlyincludes the elliptic curve encryption algorithm and the elliptic curve digital signaturealgorithm.4. Introduces the hardware part of the design and implementation. This designuses the GS1010developed by the company GainSpan. GS1010along with itsembedded software stack equipment design is a highly integrated and lowly powerconsumption of a wireless system chip, which contains802.11, media access control(MAC) and baseband processor, flash memory chip and SRAM is described, and asingle package application processor. It provides a highly scalable, reliable, andsecurity of the wireless link management, wireless sensor network, widely acceptedstandards of IEEE802.11infrastructure to meet the increasing demand. GS1010-baseddesign of a power supply module, download module, the keyboard input module,display module, serial module, USB module, sensor module and analyzed every partof the circuit process and the debugging process, finally completed system circuitdesign. Anti-jamming design was also added to the system during the design process,enhancing system stability and security.5. Mainly introduces the design of the software, first introduces the usage of akind of open source software Openssl, then completed an algorithm based on theWAPI according to the flow chart of the design of the software, and then validate theresults.On the full-text content summary, the application prospects of wireless technology are put forward.
