Tietoliikenneverkkojen tietoturvan, luottamusmekanismien ja yksityisyydensuojan tutkimusryhmä

Mitä: Turvallisuus ja luottamus ovat ensiarvoisen tärkeitä tulevaisuuden kriittisten verkkopalvelujen kannalta. Reunalaskenta, verkon viipalointi, verkkotoimintojen virtualisointi ja ohjelmiston määrittämä verkko ovat osa verkon softwarization-aaltoa, joka mahdollistaa pienemmän verkon kaistanleveyden data- ja ohjausliikenteelle, pienemmän viiveen ja suuremman skaalautuvuuden ja parantaa järjestelmätason ohjelmoitavuutta. Turvallisuus- ja luottamusmekanismit ovat tärkeämpiä kuin koskaan 5G: ssä ja 6G: ssä, koska koko yhteiskunnan kriittiset järjestelmät ovat riippuvaisia niistä.

Miksi: Kevyiden ja suorituskykyisten algoritmien suunnittelun on täytettävä 5G-järjestelmien erittäin alhaiset viivevaatimukset ja sen ulkopuolella. Uudet järjestelmäelementit 5G- ja sen ulkopuolella tuovat järjestelmään uusia uhkavektoreita, jotka on tunnustettava, ja niihin liittyviä riskejä lievennetään turvajärjestelmän suunnittelussa ja toteutuksessa. 5G- ja 5G-järjestelmien integrointi IoT- ja Industrual IoT -järjestelmiin, jotta mahdollistetaan uudet sovellusalueet, kuten älykäs liikenne, healtcare tekoälyn avulla jne., On valtava haaste teollisuudelle ja akatemialle sekä koko yhteiskunnalle.

Miten: Hajautettu prosessointi ja luottamuksen hallinta suurilla verkkolaitteiden ja toimintojen kollektiivilla, jotka voivat muuttaa niiden sijaintia ja toiminnallisuutta dynaamisesti, on vallitseva tutkimusongelma, joka vaatii uuden arkkitehtuurin suunnittelua, turvallisia avainten hallinnan ja resurssien kohdentamisalgoritmeja, niiden simulointia ja muodollista todentamista sekä testbed- ja todellista verkkotestausta ja prototyyppien tekemistä. Uusia turvallisuustekniikoita on tutkittava järjestelmällisesti, jotta voidaan selvittää niiden vahvuudet ja heikkoudet, haavoittuvuudet ja ratkaisut niiden parantamiseksi edelleen.
