Varnost mobilne telefonije

Varnost mobilne telefonije / Mobile phone security

There is no security on this earth; there is only opportunity.
— Douglas MacArthur

V letu 2012 smo Jaka Hudoklin, Matej Kovačič, Primož Bratanič in Klemen Rupnik izvedli varnostno analizo slovenskih GSM omrežij. Namen analize je bil opozoriti na varnostne ranljivosti v slovenskih GSM omrežjih in sicer zato, da se varnostne ranljivosti čim prej odpravijo, posledično pa se poveča stopnja varnosti in zasebnosti uporabnikov mobilne telefonije.

ENGLISH: Our group (Jaka Hudoklin, Matej Kovačič, Primož Bratanič and Klemen Rupnik) have performed a comprehensive security analysis of the Slovenian GSM networks in 2012. The purpose of analysis was to draw attention to security vulnerabilities in the Slovenian GSM networks and to push mobile carriers to fix them and consequently increase the level of security and privacy of mobile users.

On this website we have published several articles and lectures on mobilesecurity, some of them are also available in english language.
