摘要:

快速泄露评估(FLA,fast leakage assessment)在2017年被提出,利用“计数”的思想极大地提升了计算效率。首先对快速泄露评估的性能进行分析,然后提出基于在线计数的方法对评估流程进行改进,并使用FPGA对该方法进行实现。根据实验结果对比,所提方法不仅可以减少评估中所需要占用的内存,而且能够缩短评估所用时间,使评估效率得到明显提升。

关键词: 泄露评估, 在线处理, 高效计算, 侧信道防护

Abstract:

Fast leakage assessment (FLA) was proposed in 2017, which made use of the idea of "counter" and significantly improves the computing efficiency.The performance of FLA was analyzed, an online-counting based method was proposed to improve the evaluation flow, and the method was also validated via FPGA implementation.According to the comparisons of experimental results, the proposed method could not only decrease the required memory but also lower the runtime of the evaluation flow.Hence it can improve the evaluation efficiency significantly.

Key words: leakage assessment, online processing, efficient computation, side-channel countermeasures
