摘要: 隨著移動(dòng)通信世代的不斷演進(jìn),人類(lèi)社會(huì)從移動(dòng)互聯(lián)時(shí)代逐步邁向萬(wàn)物互聯(lián)時(shí)代,5G網(wǎng)絡(luò)將打破傳統(tǒng)移動(dòng)通信行業(yè)局限,顛覆和重塑社會(huì)發(fā)展模式,引領(lǐng)實(shí)現(xiàn)新一輪的信息革命。5G作為全新一代的移動(dòng)通信技術(shù)可為當(dāng)前物聯(lián)網(wǎng)、無(wú)人駕駛、工業(yè)互聯(lián)網(wǎng)等創(chuàng)新應(yīng)用提供基礎(chǔ)通信保障,滿(mǎn)足數(shù)據(jù)流量爆炸式增長(zhǎng)及其數(shù)以千億計(jì)的海量設(shè)備連接需求。5G安全是其全面推進(jìn)的不容忽視的核心支撐要素,首先分析研究了5G網(wǎng)絡(luò)面臨的安全風(fēng)險(xiǎn),明確了5G網(wǎng)絡(luò)安全需求,并提出了相應(yīng)的防護(hù)體系架構(gòu),對(duì)后續(xù)5G網(wǎng)絡(luò)安全技術(shù)發(fā)展有一定的借鑒意義。

Abstract: With the continuous evolution of the mobile communication generation, human society has gradually convert from the era of “Mobile Internet” to the era of “Internet of Everything”. 5G networks will break the limitations of the traditional mobile communication industry and reshape the social development model. 5G will realize a new round of information revolution. As a new generation of mobile communication technology, 5G could provide basic communication guarantee for current innovative applications, such as the Internet of Things, autonomous vehicles and industrial Internet, and meet the explosive growth of data traffic and massive device connections. Security is a core for the comprehensive promotion of 5G networks. This paper analyzes the security risks in 5G networks and clarifies its security requirements. Finally, it proposes the corresponding security architecture, which will provide reference for the subsequent development of 5G network security technology.
Key words : 5G networks;network security;security protection;security architecture

    移動(dòng)通信作為信息基礎(chǔ)設(shè)施已經(jīng)完全融入了人們生活中的方方面面,深刻改變了人類(lèi)的交互方式。移動(dòng)通信經(jīng)歷了五個(gè)世代的演進(jìn),不斷涌現(xiàn)出與時(shí)代相匹配的業(yè)務(wù)場(chǎng)景,驅(qū)動(dòng)實(shí)現(xiàn)信息技術(shù)革命性發(fā)展。

    第五代移動(dòng)通信系統(tǒng)(5G)將突破傳統(tǒng)信息交互局限,以人類(lèi)為核心,以服務(wù)為基礎(chǔ),以信息為紐帶,圍繞“信息隨心至,萬(wàn)物觸手及”的愿景構(gòu)建全方位的信息生態(tài)體系,賦能未來(lái)各個(gè)垂直行業(yè)[1-2]。5G網(wǎng)絡(luò)劃分為3種業(yè)務(wù)場(chǎng)景:增強(qiáng)移動(dòng)寬帶(Enhance Mobile Broadband,eMBB)、海量機(jī)器連接(Massive Machine Type Communication,mMTC)、超可靠低時(shí)延連接(Ultra Reliable & Low Latency Communication,uRLLC),上述3種業(yè)務(wù)場(chǎng)景通過(guò)差異化服務(wù)分別滿(mǎn)足移動(dòng)通信領(lǐng)域?qū)τ跇O高帶寬、海量物聯(lián)與時(shí)延敏感的需求[3-4]。eMBB是移動(dòng)寬帶業(yè)務(wù)場(chǎng)景的拓展,聚焦高清視頻、VR(虛擬現(xiàn)實(shí))、AR(增強(qiáng)現(xiàn)實(shí))等對(duì)移動(dòng)帶寬有極高要求的典型業(yè)務(wù)[5]。mMTC專(zhuān)注海量物聯(lián)場(chǎng)景,面向數(shù)以千億計(jì)的物聯(lián)網(wǎng)設(shè)備連接,可滿(mǎn)足智慧家居、智慧電網(wǎng)、智慧農(nóng)業(yè)等對(duì)于超大連接密度要求的業(yè)務(wù)[6]。uRLLC支持低時(shí)延與高可靠的場(chǎng)景需求,可為自動(dòng)駕駛、智慧工業(yè)等對(duì)時(shí)延極為敏感的業(yè)務(wù)提供基礎(chǔ)支撐[7]。5G引入了網(wǎng)絡(luò)切片、軟件定義網(wǎng)絡(luò)(Software Defined Network,SDN)、網(wǎng)絡(luò)功能虛擬化(Network Functions Virtualization,NFV)、移動(dòng)邊緣計(jì)算等,能夠以靈活部署、按需配置、軟硬件解耦的方式為eMBB、mMTC、uRLLC 3種業(yè)務(wù)場(chǎng)景提供差異化支持[8]。
