Analysis of Mobile Application's Compliance with the General Data Protection Regulation (GDPR)
Mangset, Peder Lind (Master thesis, 2018)Users increasingly rely on their mobile applications to fulfill everyday activities. Processing of personal data through such tools poses a significant risk to the user's privacy and security. This stems mainly from the ... -
Attacking Mobile Privacy By Catching MSISDN Location
Ottesen, Christoffer Evjen (Master thesis, 2017)Today, we find wireless technology almost everywhere. Easily, we can communicate with people on the other side of the world using our mobile phones. By June 2017, the global number of unique mobile subscribers is over 5 ... -
Attacks on the Basic cMix Design: On the Necessity of Commitments and Randomized Partial Checking
Galteland, Herman; Mjølsnes, Stig Frode; Olimid, Ruxandra-Florentina (Journal article; Peer reviewed, 2017)The cMix scheme was proposed by Chaum et al. in 2016 as the first practical set of cryptographic protocols that offer sender-recipient unlinkability at scale. The claim was that the cMix is secure unless all nodes collude. ... -
Distributed Personal Password Repository using Secret Sharing
Løland Elle, Merete; Mjølsnes, Stig Frode; Olimid, Ruxandra-Florentina (Journal article; Peer reviewed, 2018)Secret sharing based systems can provide both data secrecy and recoverability simultaneously. This is achieved by a special cryptographical splitting of the data, where the parts, called shares, are distributed among a ... -
Easy 4G/LTE IMSI Catchers for Non-Programmers
Mjølsnes, Stig Frode; Olimid, Ruxandra-Florentina (Journal article; Peer reviewed, 2017)IMSI Catchers are tracking devices that break the privacy of the subscribers of mobile access networks, with disruptive effects to both the communication services and the trust and credibility of mobile network operators. ... -
Experimental Analysis of Subscribers' Privacy Exposure by LTE Paging
Sørseth, Christian; Zhou, Xianyu Shelley; Mjølsnes, Stig Frode; Olimid, Ruxandra-Florentina (Journal article; Peer reviewed, 2018)Over the last years, considerable attention has been given to the privacy of individuals in wireless environments. Although significantly improved over the previous generations of mobile networks, LTE still exposes ... -

Sørseth, Christian; Zhou, Shelley; Mjølsnes, Stig Frode; Olimid, Ruxandra-Florentina (Journal article; Peer reviewed, 2019)Over the last years, considerable attention has been given to the privacy of individuals in wireless environments. Although significantly improved over the previous generations of mobile networks, LTE still exposes ... -
Experimental Assessment of Private Information Disclosure in LTE Mobile Networks
Mjølsnes, Stig Frode; Olimid, Ruxandra-Florentina (Chapter, 2017)Open source software running on SDR (Software Defined Radio) devices now allow building a full-fledged mobile network at low cost. These novel tools open up for exciting possibilities to analyse and verify by experiments ... -
Identity management on blockchain – privacy and security aspects
Panait, Andreea Elena; Olimid, Ruxandra-Florentina; Stefanescu, Alin (Peer reviewed; Journal article, 2020)In the last years, identity management solutions on blockchain were proposed as a possible solution to digital identity management problems. However, they are still at an early stage, and further research needs to be done ... -
Introducing Mobile Network Security Experiments to Communication Technology Education
Mjølsnes, Stig Frode; Olimid, Ruxandra-Florentina (Journal article; Peer reviewed, 2017)We describe a new viable lab assignment that enhances the theoretical study of wireless network security in our master-level communication technology education with hands-on mobile access network experimentation for the ... -
Investigation of LTE Privacy Attacks by Exploiting the Paging Mechanism
Zhou, Shelley Xianyu (Master thesis, 2018)In mobile communication in general, and LTE in particular, security should be a main focus, also because of the vulnerabilities introduced by the radio link. Compared to GSM and UMTS, the LTE security has been improved. ... -
