Title:
Corrections to ‘‘Further Improving Efficiency of Higher-Order Masking Schemes by Decreasing Randomness Complexity’’
Authors: Shuang Qiu, Rui Zhang, Yongbin Zhou, Wei Cheng
Abstract:Provably secure masking schemes always require too many random generations, which signficantly increases the implementation cost. Recently in IEEE TRANSACTIONS ON INFORMATION FORENSICS AND SECURITY (TIFS) (DOI:10.1109/TIFS.2017.2713323), Zhang, Qiu, and Zhou improve the efficiency of the CPRR scheme by decreasing the random generations. Recently, Barthe et al. claim that security flaws exist in both proposals and provide the counter-examples. In this paper, we fix these security flaws by changing the addition order. In this way, the two proposals are corrected with no extra random generation.
