摘要
Hummingbird加密算法因实现所需面积较小、功耗较低而适用于低成本射频识别标签的安全加密。为此采用SMIC 0.13μm工艺对Hummingbird算法进行硬件实现,通过降低时钟翻转频率和数据翻转频率减少动态功耗。仿真实验结果证明,Hummingbird算法可以满足电子标签对硬件开销、功耗及响应时间的实际应用要求。
Hummingbird algorithm needs small area for implementation and low power,so it is suitable for safety encryption of Radio Frequency Identification(RFID) tags.This paper uses SMIC 0.13 μm to implement Hummingbird algorithm.By reducing the unnecessary clock toggling and data toggling,it reduces dynamic power.Simulation experimental results prove that Hummingbird algorithm can meet the requirements of hardware cost,power consumption and response time.
