Encryption of Voice in GSM Network Using RC4 Algorithm

Authors(2) :-Nuha Hussain Abd Alrazig, Faisal Mohammed Abdullah

Mobile telecommunications such as Global System for Mobile Communication ( GSM ) are now well established globally and users rely heavily on the convenient communications it provides. The level of security provided by GSM is superior to its predecessors and is more than adequate for the majority of users. However, some users in the areas of government, defense or business require more security over and above that provided by the GSM standards and by standard GSM equipment. In a GSM network, only the radio channels between the mobile station (MS) and the base transceiver station (BTS) are encrypted. This paper presents methodology for implementation of end-to-end security over the available GSM infrastructure by adding encryption algorithm (RC4 algorithm) to standard GSM. The communications between parties is encrypted in GSM environments and simulation is carried using MATLAB software as simulation tool the results show thatís the proposed method can be applied and without any modification to GSM standard and optimum result can be obtained.
