5、能沒有計(jì)算機(jī)網(wǎng)絡(luò)，但是一般會有 網(wǎng)，因此通過 網(wǎng)可以與世界各地的人們聯(lián)系。不僅如此，我們通過調(diào)制與解調(diào)技術(shù)可以在 網(wǎng)上進(jìn)行數(shù)據(jù)、圖像的傳輸。 1946年，美國的AT&T公司開發(fā)設(shè)計(jì)出一種可以連接移動用戶和固定 用戶的無線 技術(shù)；基于這項(xiàng)技術(shù)，AT&T公司進(jìn)一步開發(fā)了稱之為安防移動 效勞〔MTS，Mobile Telephone Service〕安防移動通信系統(tǒng)，它的改良型I MTS系統(tǒng)在1969年開展成當(dāng)時(shí)唯一的遍布美國的樓宇對講移動通信網(wǎng)絡(luò)。1968年，AT&T公司的貝爾實(shí)驗(yàn)室創(chuàng)造了蜂窩技術(shù)，它能將樓宇對講移動通信網(wǎng)絡(luò)的覆蓋區(qū)域劃分成很多類似蜂窩的小區(qū)，相隔較遠(yuǎn)的小

6、區(qū)可以使用相同的無線電頻率。蜂窩技術(shù)的應(yīng)用極大地增加了移動通信網(wǎng)絡(luò)容量，并使小區(qū)的基站能采用低功率發(fā)射，防止高發(fā)射功率帶來的干擾問題。蜂窩技術(shù)的創(chuàng)造是移動通信史上的一個(gè)光芒里程碑，它的廣泛應(yīng)用標(biāo)志著樓宇對講移動通信進(jìn)入了蜂窩移動通信時(shí)代。 20世紀(jì)70年代末80年代初，第一代蜂窩樓宇對講移動通信網(wǎng)絡(luò)在日本、瑞典、英國、美國、德國和法國等那么多國家廣泛投入運(yùn)行。第一代蜂窩移動通信網(wǎng)絡(luò)基于模擬通信技術(shù)，采用的是頻分復(fù)用〔FDMA,Frequency Division Multiple Access〕模式，網(wǎng)絡(luò)的容量根本可以滿足移動通信用戶的需要。到了20世紀(jì)80年代末，由于模擬技術(shù)的第一代蜂窩移

7、動通信網(wǎng)絡(luò)已經(jīng)顯得過時(shí)，集成電路技術(shù)的進(jìn)步推動了數(shù)字通信技術(shù)在第二代安防蜂窩移動通信網(wǎng)絡(luò)中的應(yīng)用。如先進(jìn)的數(shù)字語音編碼技術(shù)在保證話音質(zhì)量的前提下可大大減少通信帶寬的需要提高了網(wǎng)絡(luò)頻段資源的利用率；過失控制技術(shù)增強(qiáng)了網(wǎng)絡(luò)的抗干擾能力―基站可以以低功率發(fā)射；數(shù)字加密技術(shù)可以保護(hù)數(shù)字化了的用戶語音、數(shù)據(jù)和網(wǎng)絡(luò)指令；身份證技術(shù)可以鑒別移動用戶的身份，有效防止身份假冒。所以第二代蜂窩移動通信網(wǎng)絡(luò)相比不僅性能優(yōu)良，而且平安。1990個(gè)，泛歐數(shù)字安防蜂窩移動通信網(wǎng)〔GSM，Global System for Mobile Communication〕率先在西歐各國開始運(yùn)行，讓歐洲擺脫了第一代蜂窩移動通信網(wǎng)絡(luò)

8、體制眾多互不相通的困境。GSM網(wǎng)絡(luò)在頻分復(fù)用〔FDMA〕的根底上又采用了時(shí)分多址〔FDMA〕，Time Division Multiple Access〕來增加網(wǎng)絡(luò)容量。其后，澳大利亞、中國和一些中東國家也陸續(xù)采用GSM網(wǎng)絡(luò)，使得GSM網(wǎng)絡(luò)成為世界上覆蓋范圍最大的移動通信網(wǎng)絡(luò)。 20世紀(jì)90個(gè)代末期隨著因特網(wǎng)與樓宇移動通信網(wǎng)的融合，低速率數(shù)據(jù)傳輸業(yè)務(wù)已經(jīng)無法滿足移動用戶的需求，對高速率數(shù)據(jù)傳輸業(yè)務(wù)的需求推動著移動通信網(wǎng)絡(luò)走向第三代。為此，國際電信聯(lián)盟ITU就倡導(dǎo)制定一個(gè)全球統(tǒng)一的第三代蜂窩樓宇移動通信網(wǎng)絡(luò)標(biāo)準(zhǔn)――未來公共陸地移動電信網(wǎng)絡(luò)。1998年10月由歐洲、中國、日本、韓國和美國的電信標(biāo)

9、準(zhǔn)組織聯(lián)合成立了第三代伙伴記方案〔3GPP 、the 3rd Generation Partnership Project〕組織，旨在制定一種以IS－95核心網(wǎng)絡(luò)為根底的第三代移動通信網(wǎng)絡(luò)標(biāo)準(zhǔn)CDMA2000。 第三代樓對講移動通信網(wǎng)絡(luò)在本世紀(jì)初開始投入使用，日本的DoCoMo公司于2001年10月1日率先運(yùn)營第三代移動通信網(wǎng)絡(luò)。以上我們簡單地回憶了樓宇對講移動通信的過去和開展現(xiàn)狀，在科學(xué)技術(shù)的進(jìn)步和人們對移動通信效勞需求的雙重推動下，樓宇對講移動通信網(wǎng)絡(luò)仍將繼續(xù)不斷地向前開展，更完美地實(shí)現(xiàn)廣闊樓宇對講移動通信用戶的通信效勞需求。 2 移動通信網(wǎng)絡(luò)的

10、不平安因素 無線電通信網(wǎng)絡(luò)中存在著各種不平安因素―如無線竊聽、身份假冒、篡改數(shù)據(jù)等等。樓宇對講移動通信網(wǎng)絡(luò)作為無線電通信網(wǎng)絡(luò)的一種類型同樣存在著這些不平安因素，由于樓宇對講移動通信網(wǎng)絡(luò)的特殊性，它還存在著其他類型的不平安因素。下面將從移動通信網(wǎng)絡(luò)的接口、網(wǎng)絡(luò)端和移動端三個(gè)局部分別分析其中的不平安因素，以及在安防移動通信網(wǎng)絡(luò)中的具體表現(xiàn)形成及其危害： 2.1 無線接口的不平安因素 在樓宇對講移動通信網(wǎng)絡(luò)中，移動站與固定網(wǎng)絡(luò)端之間的所有通信都是通過無線接口來傳輸?shù)?，但無線接口是開放的，作案者可通過無線接口竊聽信道而取得其中的傳輸信息，甚至可以修改、插入、刪除或重傳無線接口中的消息，到達(dá)假冒移

11、動用戶身份以欺騙網(wǎng)絡(luò)終端的目的。根據(jù)攻擊類型的不同，又可分為非授權(quán)訪部數(shù)據(jù)、非授權(quán)訪問網(wǎng)絡(luò)效勞、威脅數(shù)據(jù)完整性三種。 1．非授權(quán)訪問數(shù)據(jù)攻擊,非授權(quán)訪問數(shù)據(jù)類攻擊的主要目的在于獲取無線接口中傳輸?shù)挠脩魯?shù)據(jù)/或信令數(shù)據(jù)。其方法有如下幾種： 　 竊聽用戶數(shù)據(jù),獲取用戶信息內(nèi)容。 　 竊聽信令數(shù)據(jù),獲取網(wǎng)絡(luò)管理信息和其他有利于主動攻擊的信息。 　 無線跟蹤,獲取移動用戶的身份和位置信息，實(shí)現(xiàn)無線跟蹤。 　 被動傳輸分析,猜想用戶通信內(nèi)容和目的。 　 主動傳輸分析,獲取訪問信息。 2．非授權(quán)訪問網(wǎng)絡(luò)效勞攻擊 在非授權(quán)訪問網(wǎng)絡(luò)效勞類攻擊中，攻擊者通過假冒一個(gè)合法移動用戶身份來欺

12、騙網(wǎng)絡(luò)端，獲得授權(quán)訪問網(wǎng)絡(luò)效勞，并逃避付費(fèi)，而且由被假冒的移動用戶替攻擊者付費(fèi)。 3．威脅數(shù)據(jù)完整性攻擊 威脅數(shù)據(jù)完整性類攻擊的目標(biāo)是無線接口中的用戶數(shù)據(jù)流和信令數(shù)據(jù)流，攻擊者通過修改、插入、刪除或重傳這些數(shù)據(jù)流來實(shí)現(xiàn)欺騙數(shù)據(jù)接收方的目的，到達(dá)某種攻擊意圖。 2.2 網(wǎng)絡(luò)的不平安因素 在樓宇對講移動通信網(wǎng)絡(luò)中，網(wǎng)絡(luò)端的組成比擬復(fù)雜，它不僅包含許多功能單元，而且不同單元之間的通信媒體也不盡相同。所以安防移動通信網(wǎng)絡(luò)端同樣存在著一些不可無視的不平安因素――如無線竊聽、身份假冒、篡改數(shù)據(jù)和效勞后抵賴等等。按攻擊類型的不同，有如下四類： 1．非授權(quán)訪問數(shù)據(jù)攻擊 非授權(quán)訪問數(shù)據(jù)攻擊的主要

18、語音，防止被他人竊聽。 用戶身份保密性目的是用戶的真實(shí)身份，防止被無線跟蹤。 信令數(shù)據(jù)性目的是保護(hù)無線信道中傳送的信令數(shù)據(jù)，防止被他人竊聽。 用戶數(shù)據(jù)保密性目的是保護(hù)無線信道中傳羝的用戶數(shù)據(jù)，防止被他人竊聽。 認(rèn)證密碼保密性目的是保護(hù)SIM和AC只存儲的認(rèn)證密碼，防止被他人竊取或復(fù)制SIM。 2．認(rèn)證性平安技術(shù)業(yè)務(wù)可分為三類，它們的具體描述如下： 用戶身份認(rèn)證性目的是鑒別移動用戶身份。防止假冒用戶。 網(wǎng)絡(luò)身份認(rèn)證性目的是鑒別網(wǎng)絡(luò)身份，防止主動攻擊者假冒網(wǎng)絡(luò)進(jìn)行欺騙。 信令數(shù)據(jù)的完整性檢測目的是保護(hù)無線信道中傳送的信令信息完整性，防止被他人篡改。 3．應(yīng)用層平安技術(shù)業(yè)務(wù) 上述

19、兩類平安業(yè)務(wù)是在移動通信網(wǎng)絡(luò)的訪問層提供。隨著安防移動通信網(wǎng)絡(luò)類別培多和電子商貿(mào)開展，在應(yīng)用層增設(shè)了平安技術(shù)業(yè)務(wù)，它們的具體描述如下： 實(shí)體身份認(rèn)證,兩個(gè)應(yīng)用實(shí)體互相認(rèn)證對方的身份； 數(shù)據(jù)源認(rèn)證,接收方應(yīng)用實(shí)體認(rèn)證數(shù)據(jù)確實(shí)來自于發(fā)送方； 數(shù)據(jù)完整性認(rèn)證,接收方應(yīng)用實(shí)體確認(rèn)接收到的數(shù)據(jù)沒有被篡改； 數(shù)據(jù)保密性,保護(hù)兩應(yīng)用實(shí)體之間的數(shù)據(jù)通信，實(shí)現(xiàn)端到端保密性，防止流分析； 數(shù)據(jù)接收證明,送方應(yīng)用實(shí)體認(rèn)證可證明接收方確實(shí)收到了應(yīng)用數(shù)據(jù)。 3 移動 保護(hù) 移動 商為每部移動 分配一個(gè)全球唯一的國際移動設(shè)備號IMEI，每當(dāng)移動 訪問移動通信網(wǎng)

20、絡(luò)，它必須傳其IMEI給網(wǎng)絡(luò)端設(shè)備號登記處EIR；EIR檢查廬IMEI是否在喪失和失竊移動 的名單上，假設(shè)在那么EIR就傳一個(gè)信令將該移動 鎖起來，此時(shí)使用者自己不能開鎖，就不能繼續(xù)使用這個(gè)移動 ，這個(gè)方法在很大程度上防止了非法用戶撿來或偷來的移動 濫用網(wǎng)絡(luò)效勞，而由喪失移動 的合法用戶付費(fèi)，但是也有一些不法分子應(yīng)用高科技工具改變偷來的 的IMEI，從而通過名單檢查。為防止修改移動 的IMEI，移動 生產(chǎn)商通常將IMEI設(shè)置在一個(gè)保護(hù)的單元――具有物理防撬功能的只讀存儲器。 無線通信網(wǎng)絡(luò)中存在的不平安因素對網(wǎng)絡(luò)用戶和網(wǎng)絡(luò)經(jīng)營者經(jīng)濟(jì)利益構(gòu)成威脅，為保護(hù)他們的利益

21、，無線電通信網(wǎng)絡(luò)必須應(yīng)用上述相關(guān)技術(shù)的平安業(yè)務(wù)來消除不平安因素給網(wǎng)絡(luò)用戶帶來的威脅。隨著無線通信技術(shù)不斷開展，無線通信網(wǎng)絡(luò)的應(yīng)用不僅深入到國防軍事、科研教育、醫(yī)療衛(wèi)生等國民經(jīng)濟(jì)諸多領(lǐng)域，并已深入到千家萬戶的日常生活。無線通信網(wǎng)絡(luò)應(yīng)用越廣泛，它的平安性就越加重要。 外文參考文獻(xiàn)原文 THE SECURITY OF BULDING MOBILE COMMUNICATION TECHNOLOGY 1 The history of building mobile network Building communications network is a

(3) intimidatory data integrated attack Threatening the target that the data completeness kind attacks is consumer data stream in wireless interface and m

50、essage order data stream , the attacker deletes by modification , insertion, or weight biography realizes coming these data stream the purpose cheating a data of a receiving party's, reach some kind of attack intention. 2.2 insecure factor of network In building mobile communications network, the

51、 composition that the network holds is comparatively complicated, not only its contain many function elements , but also communication medium is also be unable completely identical between different element. Move the end communications network therefore defending against ampere same existence a few

52、assignable insecure factors eavesdroping if wireless , denying after dignity is counterfeit , tamper with a data and serve and so on. According to the diversity attacking a type's, have four resemble as follows. (1) disaccredit accessing data attack disaccredit accessing data attack to visit the c

53、onsumer data or message order data that the major objective lie in that the data attacks transfers between gaining a network holding an element, concrete method has as follows several kinds. Wiretapping users data:Gain consumer communicate by letter content. wiretapping believedata:Gain network ad

54、ministration information andinformation other beneficial to attacking on self's own initiative. wireless follow up the scent:Gain dignity and location information moving a consumer , realize wireless tracking. counterfeit communication recieve:Gain the consumer data , message order data and inform

55、ation other beneficial to attacking on self's own initiative. Visit the data that system stores illegally:Gain the data storing in system if the attestation of legal consumer parameter waits. (2) disaccredit accessing network service attack disaccredit accessing network service attack to visit th

56、e major objective that attacks being to visit a network but to evade pay a sum of money of , concrete manifestation having growing as follows almost: counterfeit legitimate，warrant gaining the visit network service. counterfeit service network，visit the network service. counterfeit adscription，ga

57、in the attestation parameter being able to palm off legal consumer dignity. abuse user authority – feast network service without any pay. abuse network service authority-Gain gain a profit of illegally. (3) Threaten entire attack of data building mobile communication the threat data completeness

58、 kind that communications network holds attacks those in including the wireless interface not only threatening data completeness kind attack , is a wireless interface because of the communication interface between BSS and MSC is also possible. And, fairly include wired communications network , concr

59、ete behaviour as follows: control user’s data,Gain the network service visiting right or disturb deliberately to communicate by letter. control persuasion data,Gain the network service visiting right or disturb deliberately to communicate by letter. counterfeit communication visitor, Gain the n

60、etwork service visiting right or disturb deliberately to communicate by letter. control download application,Disturb the regularwork of mobile terminal. control mobile terminal : Disturb the regularwork of mobile terminal. Control the data of the network stores in the element: Gain the network se

61、rvice visiting right disturbing communication deliberately. 2.3 insecure factor of miton the displacement moving communications network communications network holds building world correct talk is to be composed of station , moving a station is that it is preserving the individual information movin

62、g a consumer not only move a consumer visiting the communication implement mobile telecommunication networks,such as moving equipment international dignity number ,mobile consumer international dignity number , mobile consumer dignity attestation password and so on. Moving equipment international di

63、gnity number IMEI is a corresponding a legal consumer representing a cellular phone uniquely, but moving consumer international dignity number and the displacement consumer dignity attestation password also unique. as follows insecure since cellular phone has been brought about by cellular phone ea

64、sy to be lost or be stolen, from this in the daily life factor: Use the loss stealing or collecting the cellular phone coming on visiting the network service , being needless to pay , having been brought about economy by the consumer who loses cellular phone. The lawbreaker moves the consumer's in

65、ternational dignity number and moves the consumer dignity attestation secret key if reading out, the lawbreaker can copy a lot of cellular phone - engaged in illegal cellular phone business , give cellular phone consumer and network service business to have brought about upper loss of economy. The

66、 lawbreaker may change the number stealing or selecting cellular phone dignity coming , prevent from on this account being registered to wait a minute on the blacklist losing cellular phone. 2.4 The risk of attack The menace of the building mobile communication such as: Wireless eavesdrop , counterfeit attack , completeness infringe upon,business denies and moves telephone to attack wait a minute,concrete description as follows: Wireless eavesdrop,eavesdrop the consumer dignity number delive
