摘要:

在Nassar等提出的循环移位S盒掩码方案(RSM)的基础上,提出了一种针对高级加密标准(AES)算法低熵掩码方案。该方案的核心思想是利用S盒共用思想降低面积复杂度,采用乱序技术提高系统安全性,并通过流水线技术提高系统的吞吐量。对于AES,所提方案可将其S盒的数量从16个降低为4个(不包括密钥扩展模块)。实验表明,与RSM相比,组合逻辑、时序逻辑和存储面积分别降低了69%、60%和80%,能够抵御基于偏移量CPA攻击,具有更高的安全性。

Abstract:

Based on the rotating S-box masking (RSM) proposed by Nassar et al,a low-entropy masking scheme for the advanced encryption standard (AES) was proposed.Reducing the area complexity by reusing the S-boxes,improving the hardware security by shuffling operation and improving the throughput by pipelining operation were the main idea of the proposed scheme.For the AES,the number of S-boxes could be reduced from 16 to 4 (key expansion module wasn’t included).Compared with the RSM,the combinational logic,the dedicated logic and the memory size are reduced to 69%,60% and 80% respectively.In addition,the theoretical analysis shows that the proposed scheme can resist offset based CPA attack,thus has higher security than the RSM.

Key words: rotating S-box masking, low-entropy masking scheme, S-box reusing, AES, pipeline
