Optimized and robust implementation of mobile networks confidentiality and integrity functions

In mobile networks, sensitive information is transmitted over the radio link between Base Station (BS) and Mobile (MS). Therefore, a security mechanism based on confidentiality integrity functions designed to protect anonymity of users’. More precisely, function was standardized by Third Generation Partnership Project (3GPP) users’ data control (signaling) data. However, both are same kernel algorithm. For example, used in Universal Telecommunications System (UMTS) network algorithm, namely KASUMI block cipher. this work, we proposed an optimized that combines one Running-Block-Cipher ensures functionalities as basic (UMTS F8 F9 functions). We architectural synthesis technique allows for achieving significant reduction area occupied hardware device. The architecture implemented Xilinx Virtex Field Programmable Gate Arrays (FPGA) technology. results after place-and-route comparison with previous works show good performance terms throughput, consumed energy, logic resources.
