摘　　要：轻量级(lightweight)加密算法是应用于资源有限环境下的一类加密算法.随着射频识别技术(Radio Frequency Identification,RFID)的高速发展,促进了轻量级加密算法向小面积和低功耗的趋势发展.本文在分析现有轻量级加密算法A2U2、PRINT CIPHER和PRSENT的基础上,根据其结构特点,分别在Xilinx Virtex-5 FPGA平台上和采用0.18μm CMOS工艺的ASIC平台上实现了A2U2、PRINT CIPHER和PRSENT的低功耗硬件实现方案.设计在Synopsys的Design Compiler上的实验结果表明,提出的低功耗方案工作在100KHz时,功耗均低于2μW,与已有设计相比,具有面积小和功耗低的优点.Lightweight encryption algorithm is a type of encryption algorithm used in the extremely resource limited environment. The trend of lightweight encryption algorithm is small area and low power with the rapid development of Radio Frequency Identification （ RFID）. Based on the analysis of A2U2, PRINTCIPHER and PRSENT lightweight encryption algorithms, this paper proposed low-pow-er A2U2, low-power PRINTCIPHER and low-power PRSENT hardware implementations on Xilinx Virtex-5 FPGA platform and 0.18p.m CMOS ASIC platform according to their structure feature. The experiment results in the Design Compiler of Synopsys show that the power consumption is limited to 2μW when working at 100 KHz. Have the advantage of small area and low power consumption when compared with the existing works.
