基于有限域上的逆映射构造出了一类新的、性能优良的轻量级加密次最优(suboptimal)SOPT-S盒,通过与PRESENT等算法中S盒密码学指标进行对比分析可知,SOPT-S盒密码学特性如差分均匀度、代数次数、雪崩效应优于PRESENT中S盒,其中代数次数达到n-1,雪崩概率为1/2,均达到最佳,同时非线性度与之相等;此外,硬件方面实现规模也与之相同(4×4),从而为轻量级加密算法中分组密码的非线性层设计提供了参考。
A new lightweight S boxes based on the inverse mapping in Galois field which called suboptimal-S boxes (SOPT-S boxes)with excellent performance in cryptology was constructed. It is shown that the SOPT-S boxes perform better in cryptographic properties such as differential uniformity
algebraic degree and avalanche effect than PRESENT
of which the algebraic degree achieves to n-1
avalanche effect to 1/2 and both of them achieve to the best
besides
it has an equivalent nonlinearity compared with PRESENT. In addition
the hardware overhead is also the same as the latter
so that it can provide a reference for the designing of nonlinear layer of lightweight cryptography algorithm.
