Construction and Research of Lightweight Cryptography SOPT-S Boxes Based on Inverse Mapping in Galois Field
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.
