Abstract

In this paper a hardware implementation of ZUC stream cipher is presented. ZUC is a stream cipher that forms the heart of the 3GPP confidentiality algorithm 128-EEA3 and the 3GPP integrity algorithm 128-EIA3, offering reliable security services in Long Term Evolution networks (LTE). A detailed hardware implementation is presented in order to reach satisfactory performance results in LTE systems. The design was coded using VHDL language and for the hardware implementation, a XILINX Virtex-5 FPGA was used. Experimental results in terms of performance and hardware resources are presented.
