Secure Mobile Communication Using Low Bit-rate Coding Method

摘要：

Mobile telecommunications such as GSM are now well established globally and users rely heavily on convenient communications it provides. The level of security provided by GSM is superior to its predecessors and is more than adequate for majority of users. However some users in the area of government, defense or business require additional security over and above that provided by standard GSM equipment. But the GSM speech service is secure up to the point where speech enters the core network. In order to have an end-to-end security, speech must be encrypted before it enters the GSM network. This paper presents the feasible methodology for implementation of end-to-end security over available GSM infrastructure.
