GPRS安全体系结构的硬件实现研究

A Study on Hardware Implementation of the GPRS Security Architecture

金融业、保险业等特殊行业的高安全需求要求GPRS(GeneralPacketRadioServices)必须提供认证、数据完整性和数据机密性等安全服务。本文设计了一种GPRS安全体系结构。该体系结构使用A3、A8和GEA3算法分别实现上述安全服务。为验证该体系结构的正确性,采用VHDL硬件编程语言在Xilinx公司V400E-FG676型FPGA芯片上实现了关键算法模块,并且给出了硬件综合结果。

Some certain industries, such as finance and insurance, may require high level of security, so the GPRS should cover the authentication, data confidentiality and integrity. This paper designs a GPRS security architecture that consists of the A3 algorithm, A8 algorithm and GEA3 algorithm, which can meet these required security services. In order to verify the functional correctness of this architecture, we use the VHDL to implement these key algorithm units on XILINX V400E-FG676 FPGA device. Finally, we show the synthesis results of those proposed algorithms in details.
