Curriculum Vitae

David Rupp­recht re­cei­ved his B.​Eng. in Com­pu­ter Sci­ence and Tel­e­com­mu­ni­ca­ti­ons from the Uni­ver­si­ty of Ap­p­lied Sci­en­ces for Tel­e­com­mu­ni­ca­ti­ons Leip­zig, Ger­ma­ny, in 2012. He con­ti­nu­ed his mas­ter's de­gree in 2015 at the Ruhr-Uni­ver­si­ty Bo­chum, Ger­ma­ny where he also re­cei­ved his Ph.D. in 2020. His Ph.D. the­sis fo­cu­ses on se­cu­ring 4G and 5G net­works on the radio layer. Du­ring his re­se­arch ac­tivi­ties he has found se­ver­al im­ple­men­ta­ti­on and spe­ci­fi­ca­ti­on flaws in cur­rent and fu­ture mo­bi­le net­works. Each of these cases has led to tan­gi­b­le im­pro­ve­ments to the se­cu­ri­ty of the mo­bi­le in­dus­try, through up­dates to 3GPP stan­dards, test cases, net­work de­ploy­ments and in­dus­try good prac­tice do­cu­ments (GSMA).


My re­se­arch fo­cu­ses on mo­bi­le net­work se­cu­ri­ty, par­ti­cu­lar­ly on the LTE and 5G ac­cess net­work. Wi­t­hin this do­main, I con­cen­tra­te on spe­ci­fi­ca­ti­on, im­ple­men­ta­ti­on as well as con­fi­gu­ra­ti­on flaws. In my spare time, I cont­ri­bu­te to the srsL­TE pro­ject (https://​www.​srslte.​com/​).
