Abstract

Karakteristike pete generacije mobilnih mreža (5G) i zabrana korištenja opreme kineskih dobavljača u Australiji, Japanu, SAD-u i drugim zemljama bili su motivirajući faktori za proučavanje utjecaja dobavljača opreme na sigurnost 5G mreže i pisanje ovog rada. Opremu kineskih dobavljača sve veći broj zemalja smatra visokorizičnom pa je tako i u Europskoj Uniji preporuka izbjegavati njenu uporabu jer može ugroziti sigurnost 5G mreže. Utjecaj Kine na kineske tvrtke je značajan, zakonom je propisano osnivanje organizacije Komunističke partije i provođenje nadzora u tvrtkama te dostava zatraženih informacija. Huawei je najveći kineski dobavljač 5G opreme i iako se nastoji prilagoditi sigurnosnim zahtjevima zapadnih zemalja i mnogo ulaže u razvoj i sigurnost svoje opreme i usluga, podliježe kineskim zakonima i smatra se visokorizičnim. Cilj rada je opisati 5G tehnologiju, 5G sigurnosnu arhitekturu, vodeće dobavljače opreme s naglaskom na one visokorizične te mjere koje bi operatori trebali uzeti u obzir kod odabira dobavljača, s ciljem očuvanja povjerljivosti, cjelovitosti i dostupnosti podataka u prijenosu, obradi i pohrani. Ključne riječi: 5G, jezgrena mreža, radio pristupna mreža, virtualizacija, dijeljenje mrežnih resursa, ranjivosti, prijetnje, rizici, Kina, Toolbox, Huawei, Ericsson, Nokia

Abstract (english)

Fifth-generation mobile networks (5G) characteristics and the ban on the use of Chinese suppliers equipment in Australia, Japan, USA and other countries were motivating factors for studying the influence of equipment suppliers on 5G network security and writing this paper. An increasing number of countries considers Chinese suppliers equipment high-risk. EU recommends avoiding its use in its Member States as it can endanger 5G network security. The influence of China on Chinese companies is significant, the law prescribes the establishment of the Communist Party, carrying out supervision in companies and delivery of requested information. Huawei is China's largest 5G equipment supplier and although it strives to adapt to the security requirements of Western countries and invests heavily in the development and security of its equipment and services, it is subject to Chinese laws and is considered high-risk. The aim of the work is to describe 5G technology, 5G security architecture, leading equipment suppliers with an emphasis on high-risk ones and measures operators should take into account when choosing suppliers, with the aim of maintaining the confidentiality, integrity and availability of data while stored, processed and handled. Key words: 5G, core network, radio access network, virtualization, network slice, vulnerabilities, threats, risks, China, Toolbox, Huawei, Ericsson, Nokia
