ABSTRACT

The use of mobile phones became vital in our everyday life. This emergence has led many companies to allow new activities which were previously running strictly over the Internet to run over the mobile network such as the electronic payment. These circumstances make the security of mobile communication a priority to preserve the authentication, confidentiality and integrity of data sent between subscribers and mobile network. In this paper, we propose a dynamic key generation for the A5 GSM encryption algorithm to enforce the security and protect the transferred data. The improvement we made here is the generation and use of multiple encryption keys during a single phone communication, which makes it much harder for a cryptanalyst to eavesdrop on a phone conversation. Note that our algorithm can be implemented over any GSM generation GSM/3G/4G.
