【摘要】：隨著無(wú)線網(wǎng)絡(luò)技術(shù),通信技術(shù),硬件設(shè)計(jì)技術(shù)和傳感器技術(shù)的大規(guī)模發(fā)展和更新,物聯(lián)網(wǎng)技術(shù)作為一種非常有實(shí)用前景的技術(shù),也逐漸成為許多專家和學(xué)者研究的重點(diǎn)。無(wú)線體域網(wǎng)作為物聯(lián)網(wǎng)在個(gè)人體征信息監(jiān)測(cè)方面的一個(gè)重要分支,在當(dāng)今中國(guó)人口趨于老齡化的時(shí)代,具有較為重要的研究意義和廣闊的應(yīng)用前景。無(wú)線體域網(wǎng)技術(shù)在許多領(lǐng)域中都有應(yīng)用,比如遠(yuǎn)程醫(yī)療和監(jiān)護(hù),體感游戲,跟蹤定位,智能家居系統(tǒng)等等。無(wú)線體域網(wǎng),從人的角度看,是一種由布置于人的身體里或者表面的小型或者微型傳感器,智能移動(dòng)設(shè)備(如智能手機(jī),PDA)和遠(yuǎn)程信息中心以及各種可顯示信息的終端組成的網(wǎng)絡(luò)信息系統(tǒng)。在這些信息系統(tǒng)中,布置在人體表面或者周?chē)膫鞲衅髦饕?fù)責(zé)收集相關(guān)的人體體征信息或者與人體相關(guān)的環(huán)境數(shù)據(jù)等,然后傳感器或者直接將這些信息存儲(chǔ)在本地系統(tǒng),或者通過(guò)無(wú)線局域網(wǎng)絡(luò)發(fā)送到本地基站或者智能移動(dòng)設(shè)備,或者直接通過(guò)本地網(wǎng)關(guān)經(jīng)過(guò)因特網(wǎng)或者其他的通信網(wǎng)絡(luò)發(fā)送到遠(yuǎn)程信息處理服務(wù)系統(tǒng)。智能移動(dòng)設(shè)備可以根據(jù)需要轉(zhuǎn)發(fā)信息給遠(yuǎn)程信息系統(tǒng)。另外遠(yuǎn)程信息服務(wù)系統(tǒng)可以存儲(chǔ)和處理收集到的信息,并實(shí)時(shí)將信息的處理結(jié)果推送到各種可顯示信息的終端上,比如智能移動(dòng)終端,實(shí)時(shí)電子信息展示系統(tǒng)等。無(wú)線體域網(wǎng)系統(tǒng)是較為復(fù)雜的網(wǎng)絡(luò)應(yīng)用系統(tǒng),牽涉到無(wú)線網(wǎng)絡(luò)通信技術(shù),軟件設(shè)計(jì)技術(shù),硬件技術(shù)等等。為了使無(wú)線體域網(wǎng)系統(tǒng)規(guī)范化和讓無(wú)線體域網(wǎng)的相關(guān)研究走向標(biāo)準(zhǔn)化,2011年12月,IEEE 802.15.6工作小組針對(duì)人體周邊配置無(wú)線傳感器組建人體局域網(wǎng)的標(biāo)準(zhǔn)制定完成,近幾年也出現(xiàn)了許多無(wú)線體域網(wǎng)方面的研究成果。另一方面,無(wú)線體域網(wǎng)系統(tǒng)是為用戶個(gè)人服務(wù)的,所收集的信息主要是用戶的身體特征等,具有一定的私密性,在開(kāi)放的無(wú)線通訊網(wǎng)絡(luò)系統(tǒng)中,無(wú)線傳感器節(jié)點(diǎn)收集到的信息很容易被竊聽(tīng)或者被惡意篡改。無(wú)線體域網(wǎng)系統(tǒng)中的收集信息的節(jié)點(diǎn)具有計(jì)算能力相對(duì)較低,存儲(chǔ)空間有限,能量受限的特點(diǎn)。而且,由于人體的姿勢(shì)會(huì)不斷發(fā)生變化,無(wú)線體域網(wǎng)中的節(jié)點(diǎn)的相對(duì)位置也經(jīng)常會(huì)發(fā)生變化,導(dǎo)致無(wú)線體域網(wǎng)系統(tǒng)的結(jié)構(gòu)也會(huì)頻繁發(fā)生變化,所以,目前有許多非常有效的安全技術(shù)在我們的因特網(wǎng)中得到應(yīng)用,但是這些技術(shù)并非一定能應(yīng)用于無(wú)線體域網(wǎng)中,而是需要針對(duì)無(wú)線體域網(wǎng)的結(jié)構(gòu)和特點(diǎn)設(shè)計(jì)適用于無(wú)線體域網(wǎng)的安全方案。本文的內(nèi)容首先是從無(wú)線體域網(wǎng)本身的結(jié)構(gòu)進(jìn)行分析,并總結(jié)了無(wú)線體域網(wǎng)中安全方面的研究成果,結(jié)合無(wú)線體域網(wǎng)的安全目標(biāo)提出了一種基于隨機(jī)因子的安全方案。首先,對(duì)無(wú)線體域網(wǎng)的結(jié)構(gòu)進(jìn)行了分析,針對(duì)無(wú)線體域網(wǎng)的特點(diǎn)和結(jié)構(gòu)分析了可能的攻擊方法和安全威脅,然后對(duì)于無(wú)線體域網(wǎng)中的各個(gè)階段分別總結(jié)目前的研究中出現(xiàn)的安全技術(shù),從無(wú)線體域網(wǎng)的工作過(guò)程來(lái)看,主要分為無(wú)線體域網(wǎng)的數(shù)據(jù)收集階段,數(shù)據(jù)傳輸階段,數(shù)據(jù)聚集階段,數(shù)據(jù)存儲(chǔ)階段以及數(shù)據(jù)訪問(wèn)階段并分別分析和比較相關(guān)的安全技術(shù)。然后,從保密性,完整性等角度出發(fā),并結(jié)合抗抵賴性等需要,參考IEEE 802.15.6標(biāo)準(zhǔn),提出一種基于隨機(jī)干擾和雜湊函數(shù)的方案SASF(safety assurance start from),該方案分別考慮了從遠(yuǎn)程信息系統(tǒng),智能移動(dòng)設(shè)備,和無(wú)線傳感器節(jié)點(diǎn)開(kāi)始互相認(rèn)證身份的通信協(xié)議。接著建立了攻擊者模型,并結(jié)合有窮狀態(tài)自動(dòng)機(jī)對(duì)方案的安全性進(jìn)行了分析。接著結(jié)合arduino硬件以及溫度傳感器等進(jìn)行了仿真實(shí)驗(yàn),模擬了所設(shè)計(jì)的安全方案并對(duì)實(shí)驗(yàn)結(jié)果進(jìn)行了分析。最后,總結(jié)全文,并展望了無(wú)線體域網(wǎng)的發(fā)展前景。
[Abstract]:With the large-scale development and update of wireless network technology, communication technology, hardware design technology and sensor technology, the Internet of things, as a very useful and promising technology, has gradually become the focus of many experts and scholars. As an important branch of the personal physical information monitoring, wireless body area network (VSN) is an important branch of the Internet of things. In the age of aging population in China, it has more important research significance and broad application prospects. Wireless body domain network technology has been applied in many fields, such as telemedicine and monitoring, somatosensory games, tracking and positioning, intelligent home system and so on. Wireless body domain network, from a human point of view, is a kind of arrangement by people. A small or micro sensor in the body or surface, a network information system composed of intelligent mobile devices (such as smart phones, PDA) and remote information centers and all kinds of terminals that can display information. In these information systems, sensors arranged on or around the human body are mainly responsible for collecting relevant human physical information or information. The environment data related to the human body, and then the sensor or directly stored the information in the local system, or sent to the local base station or intelligent mobile device through the wireless local network, or sent directly through the local gateway through the Internet or other communication networks to the remote information processing service system. Intelligent mobile The equipment can forward the information to the remote information system according to the needs. In addition, the remote information service system can store and process the collected information, and push the processing results of the information to various terminals which can be displayed in real time, such as the intelligent mobile terminal, the real-time electronic information display system and so on. The wireless body domain network system is more complex. The network application system involves wireless network communication technology, software design technology, hardware technology and so on. In order to standardize the wireless body area network system and make the related research of wireless body domain network standardized, in December 2011, the IEEE 802.15.6 working group set up the standard for the establishment of the human body LAN with the wireless sensor surrounding the human body. In the past few years, there have been many research achievements in wireless body domain networks. On the other hand, the wireless body area network system is a personal service for the user. The information collected is mainly the user's physical characteristics, and has a certain privacy. In the open wireless communication network system, the information collected by the wireless sensor nodes is easy. Wiretapping or being tampered with maliciously. The nodes in the wireless body area network system have the characteristics of relatively low computing power, limited storage space and limited energy. Moreover, the relative position of the nodes in the wireless body domain network is often changed because of the constant change of the human body posture, which leads to the wireless body domain network system. The structure will also change frequently, so there are many very effective security technologies used in our Internet, but these technologies are not necessarily applied to the wireless body area network, but need to be designed for the structure and characteristics of the wireless body domain network to design a secure scheme for the non linear domain network. The content of this paper is first of all This paper analyzes the structure of WSN, and summarizes the research results of the security in WLAN. A security scheme based on random factors is proposed in combination with the security target of WSN. First, the structure of wireless body domain network is analyzed, and the possible attack is analyzed in view of the characteristics and structure of WSN. To attack the method and security threat, then summarize the security technology in the current research of the wireless body domain network. From the working process of the wireless body domain network, it is divided into the data collection stage, the data transmission stage, the data aggregation stage, the data storage stage and the data access stage. Do not analyze and compare the related security technologies. Then, from the perspective of privacy, integrity, and the need of anti repudiation, and referring to the IEEE 802.15.6 standard, a scheme SASF (safety assurance start from) based on random interference and hash function is proposed, which considers from remote information systems, intelligent mobile devices, and The wireless sensor nodes begin to authenticate the identity of the communication protocol. Then the attacker model is established, and the security of the scheme is analyzed with the finite state automata. Then the simulation experiments are carried out with the Arduino hardware and the temperature sensor, and the designed security scheme is simulated and the experimental results are analyzed. Finally, we summarize the full text and look forward to the prospect of wireless body area network.
