Since 1998 the GSM security has been academically broken but no real attack has ever been done until in 2008 when two engineers of Pico Computing (FPGA manufacture) revealed that they could break the GSM encryption in 30 seconds with 200’000$ hardware and precomputed rainbow tables. Since then the hardware was either available for rich people only or was confiscated by government agencies. So C...

Remote news reporting via fixed telephones suffers from a lack of mobility and sound quality limitations. Options for the design of a GSM/DECT dual-standard mobile terminal for broadcast news gathering are presented. Simulation results show that GSM HSCSD could carry MPEG encoded audio and occasional pictures. Computer simulations demonstrate that a mean of 3 GSM channels (aggregate of 28.8kb/s...

This paper investigates the influence of GSM speech coding on text independent speaker recognition performance. The three existing GSM speech coder standards were considered. The whole TIMIT database was passed through these coders, obtaining three transcoded databases. In a first experiment, it was found that the use of GSM coding degrades significantly the identification and verification perf...

In this paper, a new Global System of Mobile Communications (GSM) authentication protocol is proposed to improve some drawbacks of the current GSM authentication protocol for roaming users including: (a) communication overhead between VLR; (b) huge bandwidth consumption between VLR and HLR; (c) storage space overhead in VLR; (d) overloaded in HLR with authentication of mobile stations; and (e) ...

Original and modified variants of the Ghost Solid Method (GSM) are proposed for application to the boundary conditions at the solid-solid interface of isotropic elastic-plastic materials, in a Lagrangian framework. The methods are discussed for one dimensional as well as two dimensional settings with slip and no-slip conditions. It is shown, in the presence of the wave propagation through the s...

GSM-Railways (GSM-R) is a communication mobile network designed to fulfill specific communication needs of railways. GSM-R is being widely deployed across Europe and other countries around the world for providing railway voice and train control services (ETCS). Despite that, GSM-R already shows various shortcomings in terms of capacity and support for additional data services. This triggers the...

With the emergence of widely available hardware and software tools for GSM hacking, the security of cellular networks is threatened even by script kiddies. In this paper we present four different attacks in GSM networks, using commodity hardware as well as open source and freely available software tools. All attacks are performed using a common DVB-T TV tuner, which is used as a sniffer for the...

Crystals and other condensed matter systems described by density waves often exhibit dislocations. Here we show, considering the topology of ground state manifolds (GSMs) such systems, that dislocations in phase field always split into disclinations, disclinations themselves are constrained to sit at particular points GSM. Consequently, GSM forbids zero-energy dislocation glide, giving rise a P...
