【摘要】：隨著無線網(wǎng)絡技術,通信技術,硬件設計技術和傳感器技術的大規(guī)模發(fā)展和更新,物聯(lián)網(wǎng)技術作為一種非常有實用前景的技術,也逐漸成為許多專家和學者研究的重點。無線體域網(wǎng)作為物聯(lián)網(wǎng)在個人體征信息監(jiān)測方面的一個重要分支,在當今中國人口趨于老齡化的時代,具有較為重要的研究意義和廣闊的應用前景。無線體域網(wǎng)技術在許多領域中都有應用,比如遠程醫(yī)療和監(jiān)護,體感游戲,跟蹤定位,智能家居系統(tǒng)等等。無線體域網(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,智能移動設備(如智能手機,PDA)和遠程信息中心以及各種可顯示信息的終端組成的網(wǎng)絡信息系統(tǒng)。在這些信息系統(tǒng)中,布置在人體表面或者周圍的傳感器主要負責收集相關的人體體征信息或者與人體相關的環(huán)境數(shù)據(jù)等,然后傳感器或者直接將這些信息存儲在本地系統(tǒng),或者通過無線局域網(wǎng)絡發(fā)送到本地基站或者智能移動設備,或者直接通過本地網(wǎng)關經過因特網(wǎng)或者其他的通信網(wǎng)絡發(fā)送到遠程信息處理服務系統(tǒng)。智能移動設備可以根據(jù)需要轉發(fā)信息給遠程信息系統(tǒng)。另外遠程信息服務系統(tǒng)可以存儲和處理收集到的信息,并實時將信息的處理結果推送到各種可顯示信息的終端上,比如智能移動終端,實時電子信息展示系統(tǒng)等。無線體域網(wǎng)系統(tǒng)是較為復雜的網(wǎng)絡應用系統(tǒng),牽涉到無線網(wǎng)絡通信技術,軟件設計技術,硬件技術等等。為了使無線體域網(wǎng)系統(tǒng)規(guī)范化和讓無線體域網(wǎng)的相關研究走向標準化,2011年12月,IEEE 802.15.6工作小組針對人體周邊配置無線傳感器組建人體局域網(wǎng)的標準制定完成,近幾年也出現(xiàn)了許多無線體域網(wǎng)方面的研究成果。另一方面,無線體域網(wǎng)系統(tǒng)是為用戶個人服務的,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,在開放的無線通訊網(wǎng)絡系統(tǒng)中,無線傳感器節(jié)點收集到的信息很容易被竊聽或者被惡意篡改。無線體域網(wǎng)系統(tǒng)中的收集信息的節(jié)點具有計算能力相對較低,存儲空間有限,能量受限的特點。而且,由于人體的姿勢會不斷發(fā)生變化,無線體域網(wǎng)中的節(jié)點的相對位置也經常會發(fā)生變化,導致無線體域網(wǎng)系統(tǒng)的結構也會頻繁發(fā)生變化,所以,目前有許多非常有效的安全技術在我們的因特網(wǎng)中得到應用,但是這些技術并非一定能應用于無線體域網(wǎng)中,而是需要針對無線體域網(wǎng)的結構和特點設計適用于無線體域網(wǎng)的安全方案。本文的內容首先是從無線體域網(wǎng)本身的結構進行分析,并總結了無線體域網(wǎng)中安全方面的研究成果,結合無線體域網(wǎng)的安全目標提出了一種基于隨機因子的安全方案。首先,對無線體域網(wǎng)的結構進行了分析,針對無線體域網(wǎng)的特點和結構分析了可能的攻擊方法和安全威脅,然后對于無線體域網(wǎng)中的各個階段分別總結目前的研究中出現(xiàn)的安全技術,從無線體域網(wǎng)的工作過程來看,主要分為無線體域網(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)存儲階段以及數(shù)據(jù)訪問階段并分別分析和比較相關的安全技術。然后,從保密性,完整性等角度出發(fā),并結合抗抵賴性等需要,參考IEEE 802.15.6標準,提出一種基于隨機干擾和雜湊函數(shù)的方案SASF(safety assurance start from),該方案分別考慮了從遠程信息系統(tǒng),智能移動設備,和無線傳感器節(jié)點開始互相認證身份的通信協(xié)議。接著建立了攻擊者模型,并結合有窮狀態(tài)自動機對方案的安全性進行了分析。接著結合arduino硬件以及溫度傳感器等進行了仿真實驗,模擬了所設計的安全方案并對實驗結果進行了分析。最后,總結全文,并展望了無線體域網(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.
