Title:
LedMAC: More Efficient Variants of LightMAC
Authors: Yaobin Shen, Lei Wang, Dawu Gu
Abstract:LightMAC is a lightweight MAC designed by Luykx et al. and recently standardized by ISO/IEC. In this paper, we refine LightMAC and suggest two simple variants called LedMAC1 and LedMAC2. Compared to LightMAC, our first scheme LedMAC1 avoids unnecessary padding without sacrificing the security. Our second scheme LedMAC2 further reduces the number of keys from two to one, and achieves the same level security as that of LightMAC.
